All Known Implementing Classes:
DocumentImpl, DocumentWrapper, DocumentWrapper, StrippedDocument, TextFragmentValue, TinyDocumentImpl

public interface DocumentInfo
extends NodeInfo

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

This class is used not only for the root of a document, but also for the root of a result tree fragment, which is not constrained to contain a single top-level element.

Method Detail

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


getNamePool

public NamePool getNamePool()
Get the name pool used for the names in this document

Specified by:
getNamePool in interface NodeInfo
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
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

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 java.lang.String[] getUnparsedEntity(java.lang.String name)
Get the unparsed entity with a given name

Parameters:
name - the name of the entity
Returns:
if the entity exists, return an array of two Strings, the first holding the system ID of the entity, the second holding the public ID if there is one, or null if not. If the entity does not exist, return null.
