Class Orphan

    java.lang.Object
      net.sf.saxon.om.Orphan

All Implemented Interfaces:
  Item, NodeInfo, javax.xml.transform.Source, ValueRepresentation

public final class Orphan
extends java.lang.Object
implements NodeInfo

A node (implementing the NodeInfo interface) representing an attribute, text node, comment, processing instruction, or namespace that has no parent (and of course no children). Exceptionally it is also used (during whitespace stripping) to represent a standalone element.

  Specified by:
    `getStringValueCS` in interface `Item`

### getNameCode

    public int getNameCode()

  Get name code. The name code is a coded form of the node name: two nodes with the same name code have the same namespace URI, the same local name, and the same prefix.

  Specified by:
    `getFingerprint` in interface `NodeInfo`
  Returns:
    an integer fingerprint; two nodes with the same fingerprint have the same expanded QName

### getLocalPart

    public java.lang.String getLocalPart()

  Get the local part of the name of this node. This is the name after the ":" if any.

  Specified by:
    `getLocalPart` in interface `NodeInfo`
  Returns:
    the local part of the name. For an unnamed node, returns "".

### getURI

    public java.lang.String getURI()

  Specified by:
    `getPrefix` in interface `NodeInfo`
  Returns:
    The prefix of the name of the node.

### getDisplayName

    public java.lang.String getDisplayName()

    The display name of this node. For a node with no name, return an empty string.

### getParent

    public NodeInfo getParent()

  Get the NodeInfo object representing the parent of this node

  Specified by:
    `getParent` in interface `NodeInfo`
  Returns:
    null - an Orphan has no parent.

    public DocumentInfo getDocumentRoot()

  Get the root (document) node

  Specified by:
    `getDocumentRoot` in interface `NodeInfo`
  Returns:
    the DocumentInfo representing the containing document, or null if the node is not part of a document. Always null for an Orphan node.

### hasChildNodes

    public boolean hasChildNodes()

  Determine whether the node has any children.
  Note: the result is equivalent to
  getEnumeration(Axis.CHILD, AnyNodeTest.getInstance()).hasNext()

  Specified by:
    `hasChildNodes` in interface `NodeInfo`
  Returns:
    True if the node has one or more children

### generateId

    public java.lang.String generateId()

  Get a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

  Specified by:
    `generateId` in interface `NodeInfo`
  Returns:
    a string that uniquely identifies this node, within this document. The calling code prepends information to make the result unique across all documents.

### getDocumentNumber

    public int getDocumentNumber()

  Get the document number of the document containing this node. For a free-standing orphan node, just return the hashcode.

  Specified by:
    `getDocumentNumber` in interface `NodeInfo`

### copy

    public void copy(Receiver out,
                     int whichNamespaces,
                     boolean copyAnnotations,
                     int locationId)
              throws XPathException

  Copy this node to a given outputter (deep copy)

  Specified by:
    `copy` in interface `NodeInfo`
  Parameters:
    `out` - the Receiver to which the node should be copied
    `whichNamespaces` - in the case of an element, controls which namespace nodes should be copied. Values are `NodeInfo.NO_NAMESPACES`, `NodeInfo.LOCAL_NAMESPACES`, `NodeInfo.ALL_NAMESPACES`
    `copyAnnotations` - indicates whether the type annotations of element and attribute nodes should be copied
    `locationId` - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be a LocationCopier
  Throws:
    `XPathException`

### sendNamespaceDeclarations

    public void sendNamespaceDeclarations(Receiver out,
                                          boolean includeAncestors)

  Output all namespace nodes associated with this element. Does nothing if the node is not an element.

  Specified by:
    `sendNamespaceDeclarations` in interface `NodeInfo`
  Parameters:
    `out` - The relevant outputter
    `includeAncestors` - True if namespaces declared on ancestor elements must

### getDeclaredNamespaces

    public int[] getDeclaredNamespaces(int[] buffer)

  Get all namespace undeclarations and undeclarations defined on this element.

  Specified by:
    `getDeclaredNamespaces` in interface `NodeInfo`
  Parameters:
    `buffer` - If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
  Returns:
    An array of integers representing the namespace declarations and undeclarations present on this element. For a node other than an element, return null. Otherwise, the returned array is a sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The top half word of each namespace code represents the prefix, the bottom half represents the URI. If the bottom half is zero, then this is a namespace undeclaration rather than a declaration. The XML namespace is never included in the list. If the supplied array is larger than required, then the first unused entry will be set to -1.

    For a node other than an element, the method returns null.
