                java.lang.String prefix)

getPrefix

public java.lang.String getPrefix(java.lang.String namespace)

getNamespace

public java.lang.String getNamespace(java.lang.String prefix)

public boolean containsNamespace(java.lang.String namespace)

containsPrefix

public boolean containsPrefix(java.lang.String prefix)

appendNamespaces

public void appendNamespaces(java.lang.StringBuilder buf)

append xmlns:XX="..." namespace bindings for each item to buf

Parameters:

buf - buffer to append to

putAll

public void putAll(NamespaceBindings namespaceBindings)

isEmpty

public boolean isEmpty()

generatePrefix

public static java.lang.String generatePrefix(NamespaceBindings... namespaces)

generate a new prefix, unique among namespaces bindings

Parameters:

namespaces - namespaces bindings not to override

Returns:

new prefix

composeName

public static java.lang.String composeName(java.lang.String localname,
                                           java.lang.String ns,
                                           NamespaceBindings namespaces,
                                           NamespaceBindings namespacesToInsert,
                                           boolean emptyPrefixIsOK)

create a qualified name from localname, ns and given namespaces bindings. If no namespace, returns localname directly. Otherwise, pre:localname is returned, where pre is taken from namespacesToInsert then if not found from namespaces, then is generated to be unique among namespaces and namespacesToInsert (always of the form nsNUMBER).

Parameters:

localname - local name

ns - namespace localname is in

namespaces - already declared namespaces

namespacesToInsert - new namespaces (IN/OUT: a new binding may be added)

emptyPrefixIsOK - is empty prefix OK for non null namespace ? (false for attributes

Returns:

the qualified name
