Class DocumentWrapper

Implemented Interfaces:
DocumentInfo, NodeInfo, Source

public class DocumentWrapper
extends NodeWrapper
implements DocumentInfo

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

This class should have been named Root; it 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.

Constructor Details

DocumentWrapper

public DocumentWrapper(Document doc,
                       String baseURI)

Method Details

getKeyIndex

public Hashtable getKeyIndex(KeyManager keyManager,
                             int fingerprint)
Get the index for a given key
Specified by:
getKeyIndex in interface DocumentInfo
Parameters:
fingerprint - The fingerprint of the name of the key (unique with the key manager)
Returns:
The index, if one has been built, in the form of a Hashtable that maps the key value to a list of nodes having that key value. If no index has been built, returns null.

getNamePool

public NamePool getNamePool()
Get the name pool used for the names in this document
Specified by:
getNamePool in interface DocumentInfo

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: JDOM does not provide access to unparsed entities

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:
null: JDOM does not provide any information about attribute types.

setKeyIndex

public void setKeyIndex(KeyManager keyManager,
                        int fingerprint,
                        Hashtable index)
Set the index for a given key
Specified by:
setKeyIndex in interface DocumentInfo
Parameters:
fingerprint - The fingerprint of the name of the key (unique with the key manager)
index - the index, in the form of a Hashtable that maps the key value to a list of nodes having that key value

setNamePool

public void setNamePool(NamePool pool)
Set the name pool used for all names in this document
Specified by:
setNamePool in interface DocumentInfo
