## net.sf.saxon.tree.util
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
