String |
checkContext(int i)
This method is used to restore the namespace state
after an element is created.
|
void |
endPrefixMapping(String pPrefix)
Removes the declaration of the prefix, which has been defined
last.
|
String |
getAttributePrefix(String pURI)
Returns a non-empty prefix currently mapped to the given
URL or null, if there is no such mapping.
|
int |
getContext()
Returns the current number of assigned prefixes.
|
String |
getNamespaceURI(String pPrefix)
Given a prefix, returns the URI to which the prefix is
currently mapped or null, if there is no such mapping.
|
String |
getPrefix(String pURI)
Returns a prefix currently mapped to the given URI or
null, if there is no such mapping.
|
List |
getPrefixes()
Returns a list of all prefixes, which are currently declared,
in the order of declaration.
|
Iterator |
getPrefixes(String pURI)
Returns a collection to all prefixes bound to the given
namespace URI.
|
boolean |
isPrefixDeclared(String pPrefix)
Returns whether a given prefix is currently declared.
|
void |
reset()
Resets the NamespaceSupport's state.
|
void |
startPrefixMapping(String pPrefix,
String pURI)
Declares a new prefix.

- The prefix is null.IllegalStateException
- The prefix is not the prefix, which
has been defined last. In other words, the calls to
startPrefixMapping(String, String)
, and
endPrefixMapping(String)
aren't in LIFO order.public String getNamespaceURI(String pPrefix)

The return value is used as a saveable state. After
invoking
ContentHandler.endElement(String, String, String)
,
the state is restored by calling checkContext(int)
