    public class DocumentWrapper

extends NodeWrapper
implements DocumentInfo

The root node of an XPath tree. (Or equivalently, the tree itself).

This class is used not only for a document, but also for the root of a document-less tree fragment.

Constructor Detail

### DocumentWrapper

    public DocumentWrapper(Node root,
                           String baseURI,
                           Configuration config)

  Create a Saxon wrapper for a XOM root node

  Parameters:
    `root` - The XOM root node
    `baseURI` - The base URI for all the nodes in the tree
    `config` - The configuration which defines the name pool used for all names in this tree

Method Detail

### wrap

    public NodeInfo wrap(Node node)

  Wrap a node in the XOM document.

  Parameters:
    `node` - The node to be wrapped. This must be a node in the same document (the system does not check for this).
  Returns:
    the wrapping NodeInfo object

### setConfiguration

    public void setConfiguration(Configuration config)

  Set the configuration, which defines the name pool used for all names in this document. This is always called after a new document has been created. The implementation must register the name pool with the document, so that it can be retrieved using getNamePool(). It must also call NamePool.allocateDocumentNumber(), and return the relevant document number when getDocumentNumber() is subsequently called.

  Parameters:
    `config` - The configuration to be used

### getConfiguration

    public Configuration getConfiguration()

  Get the configuration previously set using setConfiguration

  Specified by:
    `getConfiguration` in interface `NodeInfo`
  Overrides:
    `getConfiguration` in class `NodeWrapper`
  Returns:
    the Configuration

### getNamePool

    public NamePool getNamePool()

  Get the name pool used for the names in this document

  Specified by:
    `getNamePool` in interface `NodeInfo`
  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 for this document (the number is unique for all documents within a NamePool)

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

### selectID

    public NodeInfo selectID(String id)

  Get the element with a given ID, if any

  Specified by:
    `selectID` in interface `DocumentInfo`
  Parameters:
    `id` - the required ID value
  Returns:
    the element with the given ID, or null if there is no such ID present (or if the parser has not notified attributes as being of type ID).

### getUnparsedEntity

    public String[] getUnparsedEntity(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: XOM does not provide access to unparsed entities
