com.icl.saxon.om.DocumentPool
public final class DocumentPool
extends java.lang.Object
An object representing the collection of documents handled during
a single transformation
add
public int add(DocumentInfo doc,
String name)
Add a document to the pool, and allocate a document number
doc
- The DocumentInfo for the document in questionname
- The name of the document. May be null, in the case of
the principal source document or a result tree fragment. Used for
the URI of a document loaded using the document() function.
- the document number, unique within this document pool
find
public DocumentInfo find(String name)
Get the document with a given name
- the DocumentInfo with the given name if it exists,
or null if it is not found.
getDocumentNumber
public int getDocumentNumber(DocumentInfo doc)
Get the document number of a document that is already in the pool.
If the document is not already in the pool, it is added, and a document
number is allocated. (This can happen when a Java application has built
the document independently of the Controller. In this case, it is still
necessary that all documents use the same NamePool, but we don't actually
check this).
- the document number
getNumberOfDocuments
public int getNumberOfDocuments()
Get the number of documents in the pool
