Interface NamespaceContext

All Known Implementing Classes:

NamespaceSupport

@Deprecated(since="2021-03-05")
public interface NamespaceContext

Deprecated.

Please avoid using this package and use standard XML APIs.

Represents an interface to query namespace information.

The prefix and namespace must be identical references for equal strings, thus each string should be internalized (@see String.intern()) or added to the SymbolTable

Field Detail

XML_URI

static final String XML_URI

Deprecated.

The XML Namespace ("http://www.w3.org/XML/1998/namespace"). This is the Namespace URI that is automatically mapped to the "xml" prefix.

XMLNS_URI

static final String XMLNS_URI

Deprecated.

XML Information Set REC all namespace attributes (including those named xmlns, whose [prefix] property has no value) have a namespace URI of http://www.w3.org/2000/xmlns/

Method Detail

pushContext

void pushContext()

Deprecated.

Start a new Namespace context.

A new context should be pushed at the beginning of each XML element: the new context will automatically inherit the declarations of its parent context, but it will also keep track of which declarations were made within this context.

See Also:

popContext()

popContext

void popContext()

Deprecated.

Revert to the previous Namespace context.

The context should be popped at the end of each XML element. After popping the context, all Namespace prefix mappings that were previously in force are restored.

Users must not attempt to declare additional Namespace prefixes after popping a context, unless you push another context first.

See Also:

pushContext()

declarePrefix

boolean declarePrefix(String prefix,
                      String uri)

Deprecated.

Declare a Namespace prefix.

This method declares a prefix in the current Namespace context; the prefix will remain in force until this context is popped, unless it is shadowed in a descendant context.

Note that to declare a default Namespace, use the empty string. The prefixes "xml" and "xmlns" can't be rebound.

Note that you must not declare a prefix after you've pushed and popped another Namespace.

Parameters:

prefix - The prefix to declare, or null for the empty string.

uri - The Namespace URI to associate with the prefix.

Returns:

true if the prefix was legal, false otherwise

See Also:

getURI(java.lang.String), getDeclaredPrefixAt(int)

getURI

String getURI(String prefix)

Deprecated.

Look up a prefix and get the currently-mapped Namespace URI.

This method looks up the prefix in the current context. If no mapping is found, this methods will continue lookup in the parent context(s). Use the empty string ("") for the default Namespace.

Parameters:

prefix - The prefix to look up.

Returns:

The associated Namespace URI, or null if the prefix is undeclared in this context.

getPrefix

String getPrefix(String uri)

Deprecated.

Look up a namespace URI and get one of the mapped prefix.

This method looks up the namespace URI in the current context. If more than one prefix is currently mapped to the same URI, this method will make an arbitrary selection If no mapping is found, this methods will continue lookup in the parent context(s).

Parameters:

uri - The namespace URI to look up.

Returns:

One of the associated prefixes, or null if the uri does not map to any prefix.

See Also:

getPrefix(java.lang.String)

getDeclaredPrefixCount

int getDeclaredPrefixCount()

Deprecated.

Return a count of locally declared prefixes, including the default prefix if bound.

getDeclaredPrefixAt

String getDeclaredPrefixAt(int index)

Deprecated.

Returns the prefix at the specified index in the current context.

getAllPrefixes

Enumeration getAllPrefixes()

Deprecated.

Return an enumeration of all prefixes whose declarations are active in the current context. This includes declarations from parent contexts that have not been overridden.

Returns:

Enumeration

reset

void reset()

Deprecated.

Reset this Namespace support object for reuse.

It is necessary to invoke this method before reusing the Namespace support object for a new session.

Note that implementations of this method need to ensure that the declaration of the prefixes "xmlns" and "xml" are available.
