Class DiagnosticNamePool

java.lang.Object
  net.sf.saxon.om.NamePool
      net.sf.saxon.tree.util.DiagnosticNamePool

All Implemented Interfaces:

Serializable

public class DiagnosticNamePool
extends NamePool

This class provides a diagnostic wrapper for the real NamePool. There are no formal interfaces to exploit it, but it can be patched into a system by use of setNamePool() on the Configuration, and its effect is to trace entry to selected methods, notably those that are synchronized, for diagnostic analysis.

Method Detail

allocateNamespaceCode

public int allocateNamespaceCode(String prefix,
                                 String uri)

Description copied from class: NamePool

Allocate the namespace code for a namespace prefix/URI pair. Create it if not already present

Overrides:

allocateNamespaceCode in class NamePool

Parameters:

prefix - the namespace prefix

uri - the namespace URI

Returns:

an integer code identifying the namespace. The namespace code identifies both the prefix and the URI.

allocateCodeForURI

public short allocateCodeForURI(String uri)

Description copied from class: NamePool

Allocate the uri code for a given URI; create one if not found

Overrides:

allocateCodeForURI in class NamePool

Parameters:

uri - The namespace URI. Supply "" or null for the "null namespace"

Returns:

an integer code that uniquely identifies this URI within the namepool.

allocate

public int allocate(String prefix,
                    String uri,
                    String localName)

Description copied from class: NamePool

Allocate a name from the pool, or a new Name if there is not a matching one there

Overrides:

allocate in class NamePool

Parameters:

prefix - the namespace prefix. Use "" for the null prefix, representing the absent namespace

uri - the namespace URI. Use "" or null for the non-namespace.

localName - the local part of the name

Returns:

an integer (the "namecode") identifying the name within the namepool. The Name itself may be retrieved using the getName(int) method
