Field Detail

### config

### baseURI

    protected java.lang.String baseURI

### documentNumber

    protected int documentNumber

Constructor Detail

### DocumentWrapper

    public DocumentWrapper(org.w3c.dom.Document doc,
                           java.lang.String baseURI,
                           Configuration config)

Method Detail

### wrap

    public NodeWrapper wrap(org.w3c.dom.Node node)

  Create a wrapper for a node in this document

  Parameters:
    `node` - the DOM node to be wrapped. This must be a node within the document wrapped by this DocumentWrapper

### setConfiguration

    public void setConfiguration(Configuration config)

  Set the Configuration that contains this document

  Specified by:
    `setConfiguration` in interface `DocumentInfo`
  Parameters:
    `config` - The configuration to be used

### getConfiguration

    public Configuration getConfiguration()

  Get the configuration previously set using setConfiguration

  Specified by:
    `getConfiguration` in interface `DocumentInfo`

### getNamePool

    public NamePool getNamePool()

  Get the name pool used for the names in this document

  Specified by:
    `getNamePool` in interface `DocumentInfo`
  Overrides:
    `getNamePool` in class `NodeWrapper`
  Returns:
    the name pool in which all the names used in this document are registered

### getDocumentNumber

    public int getDocumentNumber()

  Get the unique document number

  Specified by:
    `getDocumentNumber` in interface `DocumentInfo`
  Overrides:
    `getDocumentNumber` in class `NodeWrapper`
  Returns:
    the unique number identifying this document within the name pool

### selectID

    public NodeInfo selectID(java.lang.String id)

  Get the element with a given ID, if any

  Specified by:
    `selectID` in interface `DocumentInfo`
  Parameters:
    `id` - the required ID value
  Returns:
    a NodeInfo representing the element with the given ID, or null if there is no such element. This implementation does not necessarily conform to the rule that if an invalid document contains two elements with the same ID, the one that comes last should be returned.

### isSameNodeInfo

    public boolean isSameNodeInfo(NodeInfo other)

  Determine whether this is the same node as another node.
  Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

  Specified by:
    `isSameNodeInfo` in interface `NodeInfo`
  Overrides:
    `isSameNodeInfo` in class `NodeWrapper`
  Parameters:
    `other` - the node to be compared with this node
  Returns:
    true if this Node object and the supplied Node object represent the same node in the tree.

### getUnparsedEntity

    public java.lang.String[] getUnparsedEntity(java.lang.String name)

  Get the unparsed entity with a given name

  Specified by:
    `getUnparsedEntity` in interface `DocumentInfo`
  Parameters:
    `name` - the name of the entity
  Returns:
    null: JDOM does not provide access to unparsed entities
