Class BijectiveNsMap

java.lang.Object

com.ctc.wstx.util.BijectiveNsMap

public final class BijectiveNsMap
extends Object

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.

Currently only used by stream writers, but could be more generally useful too.

Method Detail

createEmpty

public static BijectiveNsMap createEmpty()

createChild

public BijectiveNsMap createChild()

findUriByPrefix

public String findUriByPrefix(String prefix)

findPrefixByUri

public String findPrefixByUri(String uri)

getPrefixesBoundToUri

public List<String> getPrefixesBoundToUri(String uri,
                                 List<String> l)

size

public int size()

localSize

public int localSize()

addMapping

public String addMapping(String prefix,
                String uri)

Method to add a new prefix-to-URI mapping for the current scope. Note that it should NOT be used for the default namespace declaration

Parameters:

prefix - Prefix to bind

uri - URI to bind to the prefix

Returns:

If the prefix was already bound, the URI it was bound to: null if it's a new binding for the current scope.

addGeneratedMapping

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.

toString

public String toString()

Overrides:

toString in class Object
