## Member Typedef Documentation

typedef XERCES_CPP_NAMESPACE_QUALIFIER DOM_Text XercesTextBridge::DOM_TextType

## Constructor & Destructor Documentation

XercesTextBridge::XercesTextBridge ( | const DOM_TextType & theXercesText,
| const XercesBridgeNavigator & theNavigator )

XercesTextBridge::~XercesTextBridge ( | )`[virtual]`

## Member Function Documentation

XalanNode * XercesTextBridge::appendChild ( | XalanNode * newChild )`[virtual]`

  | Adds the node `newChild` to the end of the list of children of this node. If the `newChild` is already in the tree, it is first removed. Parameters:
  newChild | The node to add.If it is a `DocumentFragment` object, the entire contents of the document fragment are moved into the child list of this node
Returns: The node added. Reimplemented from XalanText.

void XercesTextBridge::appendData ( | const XalanDOMString & arg )`[virtual]`

  | Append the string to the end of the character data of the node. Upon success, `data` provides access to the concatenation of `data` and the `DOMString` specified. Parameters:
  arg | The `DOMString` to append.
  Exceptions:
  DOMException | NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
Reimplemented from XalanText.

XercesTextBridge * XercesTextBridge::cloneNode ( | bool deep ) const`[virtual]`

  | Returns a duplicate of this node. This function serves as a generic copy constructor for nodes. The duplicate node has no parent ( `parentNode` returns `null`.). Cloning an `Element` copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child `Text` node. Cloning any other type of node simply returns a copy of this node. Parameters:
  deep | If `true`, recursively clone the subtree under the specified node; if `false`, clone only the node itself (and its attributes, if it is an `Element`).
Returns: The duplicate node. Reimplemented from XalanText.

void XercesTextBridge::deleteData ( | unsigned int offset,
| unsigned int count )`[virtual]`

  | Remove a range of characters from the node. Upon success, `data` and `length` reflect the change. Parameters:
  offset | The offset from which to remove characters.
  count | The number of characters to delete. If the sum of `offset` and `count` exceeds `length` then all characters from `offset` to the end of the data are deleted.
  Exceptions:
  DOMException | INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in `data`, or if the specified `count` is negative. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
Reimplemented from XalanText.

const XalanNamedNodeMap * XercesTextBridge::getAttributes ( | ) const`[virtual]`

| Gets a `NamedNodeMap` containing the attributes of this node (if it is an `Element`) or `null` otherwise. Reimplemented from XalanText.

const XalanNodeList * XercesTextBridge::getChildNodes ( | ) const`[virtual]`

| Gets a `NodeList` that contains all children of this node. If there are no children, this is a `NodeList` containing no nodes. The content of the returned `NodeList` is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the `NodeList` accessors; it is not a static snapshot of the content of the node. This is true for every `NodeList`, including the ones returned by the `getElementsByTagName` method. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getData ( | ) const`[virtual]`

  | Returns the character data of the node that implements this interface. The DOM implementation may not put arbitrary limits on the amount of data that may be stored in a `CharacterData` node. However, implementation limits may mean that the entirety of a node's data may not fit into a single `DOMString`. In such cases, the user may call `substringData` to retrieve the data in appropriately sized pieces. Exceptions:
  DOMException | NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
  DOMException | DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a `DOMString` variable on the implementation platform.
Reimplemented from XalanText.

XalanNode * XercesTextBridge::getFirstChild ( | ) const`[virtual]`

| Gets the first child of this node. If there is no such node, this returns `null`. Reimplemented from XalanText.

IndexType XercesTextBridge::getIndex ( | ) const`[virtual]`

| Get the node's index. Valid only if the owner document reports that the document is node-order indexed. Returns: The index value, or 0 if the node is not indexed. Reimplemented from XalanText.

XalanNode * XercesTextBridge::getLastChild ( | ) const`[virtual]`

| Gets the last child of this node. If there is no such node, this returns `null`. Reimplemented from XalanText.

unsigned int XercesTextBridge::getLength ( | ) const`[virtual]`

| Returns the number of characters that are available through `data` and the `substringData` method below. This may have the value zero, i.e., `CharacterData` nodes may be empty. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getLocalName ( | ) const`[virtual]`

| Returns the local part of the qualified name of this node. For nodes created with a DOM Level 1 method, such as `createElement` from the `DOM_Document` interface, it is null. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getNamespaceURI ( | ) const`[virtual]`

| Get the namespace URI of this node, or `null` if it is unspecified. This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time. For nodes of any type other than `ELEMENT_NODE` and `ATTRIBUTE_NODE` and nodes created with a DOM Level 1 method, such as `createElement` from the `Document` interface, this is always `null`. Reimplemented from XalanText.

XalanNode * XercesTextBridge::getNextSibling ( | ) const`[virtual]`

| Gets the node immediately following this node. If there is no such node, this returns `null`. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getNodeName ( | ) const`[virtual]`

| Gets the name of this node. Reimplemented from XalanText.

NodeType XercesTextBridge::getNodeType ( | ) const`[virtual]`

| An enum value representing the type of the underlying object. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getNodeValue ( | ) const`[virtual]`

| Gets the value of this node, depending on its type. Reimplemented from XalanText.

XalanDocument * XercesTextBridge::getOwnerDocument ( | ) const`[virtual]`

| Gets the `DOM_Document` object associated with this node. This is also the `DOM_Document` object used to create new nodes. When this node is a `DOM_Document` or a `DOM_DocumentType` which is not used with any `DOM_Document` yet, this is `null`. Reimplemented from XalanText.

XalanNode * XercesTextBridge::getParentNode ( | ) const`[virtual]`

| Gets the parent of this node. All nodes, except `Document`, `DocumentFragment`, and `Attr` may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, a `null` DOM_Node is returned. Reimplemented from XalanText.

const XalanDOMString & XercesTextBridge::getPrefix ( | ) const`[virtual]`

| Get the namespace prefix of this node, or `null` if it is unspecified. Reimplemented from XalanText.

XalanNode * XercesTextBridge::getPreviousSibling ( | ) const`[virtual]`

| Gets the node immediately preceding this node. If there is no such node, this returns `null`. Reimplemented from XalanText.

DOM_TextType XercesTextBridge::getXercesNode ( | ) const

| Get the Xerces node this instance represent. Returns: The Xerces node

bool XercesTextBridge::hasChildNodes ( | ) const`[virtual]`

| This is a convenience method to allow easy determination of whether a node has any children. Returns: `true` if the node has any children, `false` if the node has no children. Reimplemented from XalanText.

XalanNode * XercesTextBridge::insertBefore ( | XalanNode * newChild,
| XalanNode * refChild )`[virtual]`

  | Inserts the node `newChild` before the existing child node `refChild`. If `refChild` is `null`, insert `newChild` at the end of the list of children. If `newChild` is a `DocumentFragment` object, all of its children are inserted, in the same order, before `refChild`. If the `newChild` is already in the tree, it is first removed. Note that a `DOM_Node` that has never been assigned to refer to an actual node is == null. Parameters:
  newChild | The node to insert.
  refChild | The reference node, i.e., the node before which the new node must be inserted.
Returns: The node being inserted. Reimplemented from XalanText.

void XercesTextBridge::insertData ( | unsigned int offset,
| const XalanDOMString & arg )`[virtual]`

  | Insert a string at the specified character offset. Parameters:
  offset | The character offset at which to insert.
  arg | The `DOMString` to insert.
  Exceptions:
  DOMException | INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in `data`. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
Reimplemented from XalanText.

bool XercesTextBridge::isIgnorableWhitespace ( | ) const`[virtual]`

| Determine whether the text node instance is composed entirely of XML whitespace. Returns: true if the node is all XML whitespace, false if not Reimplemented from XalanText.

bool XercesTextBridge::isIndexed ( | ) const`[virtual]`

| Determine if the document is node-order indexed. Returns: true if the document is indexed, otherwise false. Reimplemented from XalanText.

bool XercesTextBridge::isSupported ( | const XalanDOMString & feature,
| const XalanDOMString & version ) const`[virtual]`

  | Tests whether the DOM implementation implements a specific feature and that feature is supported by this node. Parameters:
  feature | The string of the feature to test. This is the same name as what can be passed to the method `hasFeature` on `DOMImplementation`.
  version | This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return `true`.
Returns: Returns `true` if the specified feature is supported on this node, `false` otherwise. Reimplemented from XalanText.

void XercesTextBridge::normalize ( | )`[virtual]`

| Puts all `DOM_Text` nodes in the full depth of the sub-tree underneath this `DOM_Node`, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates `DOM_Text` nodes, i.e., there are no adjacent `DOM_Text` nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used. Note: In cases where the document contains `DOM_CDATASections`, the normalize operation alone may not be sufficient, since XPointers do not differentiate between `DOM_Text` nodes and `DOM_CDATASection` nodes. Reimplemented from XalanText.

XalanNode * XercesTextBridge::removeChild ( | XalanNode * oldChild )`[virtual]`

  | Removes the child node indicated by `oldChild` from the list of children, and returns it. Parameters:
  oldChild | The node being removed.
Returns: The node removed. Reimplemented from XalanText.

XalanNode * XercesTextBridge::replaceChild ( | XalanNode * newChild,
| XalanNode * oldChild )`[virtual]`

  | Replaces the child node `oldChild` with `newChild` in the list of children, and returns the `oldChild` node. If `newChild` is a `DOM_DocumentFragment` object, `oldChild` is replaced by all of the `DOM_DocumentFragment` children, which are inserted in the same order. If the `newChild` is already in the tree, it is first removed. Parameters:
  newChild | The new node to put in the child list.
  oldChild | The node being replaced in the list.
Returns: The node replaced. Reimplemented from XalanText.

void XercesTextBridge::replaceData ( | unsigned int offset,
| unsigned int count,
| const XalanDOMString & arg )`[virtual]`

  | Replace the characters starting at the specified character offset with the specified string. Parameters:
  offset | The offset from which to start replacing.
  count | The number of characters to replace. If the sum of `offset` and `count` exceeds `length` , then all characters to the end of the data are replaced (i.e., the effect is the same as a `remove` method call with the same range, followed by an `append` method invocation).
  arg | The `DOMString` with which the range must be replaced.
  Exceptions:
  DOMException | INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in `data`, or if the specified `count` is negative. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
Reimplemented from XalanText.

void XercesTextBridge::setNodeValue ( | const XalanDOMString & nodeValue )`[virtual]`

| Sets the value of the node. Any node which can have a nodeValue ( See also: getNodeValue) will also accept requests to set it to a string. The exact response to this varies from node to node -- Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value. For most types of Node, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only. Reimplemented from XalanText.

void XercesTextBridge::setPrefix ( | const XalanDOMString & prefix )`[virtual]`

  | Set the namespace prefix of this node. Note that setting this attribute, when permitted, changes the `nodeName` attribute, which holds the qualified name, as well as the `tagName` and `name` attributes of the `DOM_Element` and `DOM_Attr` interfaces, when applicable. Note also that changing the prefix of an attribute, that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the `namespaceURI` and `localName` do not change. Parameters:
  prefix | The prefix of this node.
  Exceptions:
  DOMException | INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. NAMESPACE_ERR: Raised if the specified `prefix` is malformed, if the specified prefix is "xml" and the `namespaceURI` of this node is different from "http://www.w3.org/XML/1998/namespace", if specified prefix is "xmlns" and the `namespaceURI` is neither `null` nor an empty string, or if the `localName` is `null`.
Reimplemented from XalanText.

XalanText * XercesTextBridge::splitText ( | unsigned int offset )`[virtual]`

  | Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings. This node then only contains all the content up to the `offset` point. And a new node of the same nodeType, which is inserted as the next sibling of this node, contains all the content at and after the `offset` point. When the `offset` is equal to the lenght of this node, the new node has no data. Parameters:
  offset | The offset at which to split, starting from 0.
  Returns: The new `Text` node. Exceptions:
  DOMException | INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in `data`. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
Reimplemented from XalanText.

XalanDOMString XercesTextBridge::substringData ( | unsigned int offset,
| unsigned int count ) const`[virtual]`

  | Extracts a range of data from the node. Parameters:
  offset | Start offset of substring to extract.
  count | The number of characters to extract.
  Returns: The specified substring. If the sum of `offset` and `count` exceeds the `length`, then all characters to the end of the data are returned. Exceptions:
  DOMException | INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in `data`, or if the specified `count` is negative. DOMSTRING_SIZE_ERR: Raised if the specified range of text does not fit into a `DOMString`.
