Class DocumentPool

  +--net.sf.saxon.om.DocumentPool

public final class DocumentPool
extends java.lang.Object

An object representing the collection of documents handled during a single transformation.

From Saxon 7.2, the function of allocating document numbers is performed by the NamePool, not by the DocumentPool. This has a number of effects: in particular it allows operations involving multiple documents (such as generateId() and document()) to occur in a free-standing XPath environment.

                java.lang.String name)
Add a document to the pool

Parameters:

Get the document with a given name

Returns:
the DocumentInfo with the given name if it exists, or null if it is not found.
