public final Class BijectiveNsMap

extends Object
Class Inheritance
Imports
java.util.*, javax.xml.XMLConstants, javax.xml.namespace.NamespaceContext
Helper class that implements "bijective map" (Map that allows use of values as keys and vice versa, bidirectional access), and is specifically used for storing namespace binding information. One thing worth noting is that Strings stored are NOT assumed to have been unified (interned) -- if they were, different implementation would be more optimal.

Field Summary

Modifier and TypeField and Description
pack-priv String[]
_nsStrings

Array that contains { prefix, ns-uri } pairs, up to (but not including) index _scopeEnd.

pack-priv int
_scopeEnd

pack-priv final int
_scopeStart

pack-priv static final int
DEFAULT_ARRAY_SIZE

Let's plan for having up to 14 explicit namespace declarations (2 defaults, for 'xml' and 'xmlns', are pre-populated)

Method Summary

Modifier and TypeMethod and Description
public String
addGeneratedMapping(String prefixBase, NamespaceContext ctxt, String uri, int[] seqArr)

Method used to add a dynamic binding, and return the prefix used to bind the specified namespace URI.

public String

Returns:

If the prefix was already bound, the URI it was bound to: null if it's a new binding for the current scope.
addMapping(String
Prefix to bind
prefix, String
URI to bind to the prefix
uri)

Method to add a new prefix-to-URI mapping for the current scope.
