java.lang.Object net.sf.saxon.om.DocumentPool
public final class DocumentPool
An object representing the collection of documents handled during a single transformation.
The function of allocating document numbers is performed by the DocumentNumberAllocator in the Configuration, 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.
