Class NamespaceContextImpl

java.lang.Object

net.sf.saxon.pull.NamespaceContextImpl

All Implemented Interfaces:

javax.xml.namespace.NamespaceContext, NamespaceResolver

public class NamespaceContextImpl
extends java.lang.Object
implements javax.xml.namespace.NamespaceContext, NamespaceResolver

This class bridges between the JAXP 1.3 NamespaceContext interface and Saxon's equivalent NamespaceResolver interface. It allows any implementation of the Saxon NamespaceResolver to be wrapped as a JAXP NamespaceContext.

NamespaceContextImpl

public NamespaceContextImpl(NamespaceResolver resolver)

Constructor: wrap a Saxon NamespaceResolver as a JAXP NamespaceContext

Parameters:

resolver - the Saxon NamespaceResolver

Method Detail

getURIForPrefix

public java.lang.String getURIForPrefix(java.lang.String prefix,
                                        boolean useDefault)

Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.

Specified by:

getURIForPrefix in interface NamespaceResolver

Parameters:

prefix - the namespace prefix

useDefault - true if the default namespace is to be used when the prefix is ""

Returns:

the uri for the namespace, or null if the prefix is not in scope

iteratePrefixes

public java.util.Iterator<java.lang.String> iteratePrefixes()

Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate

Specified by:

iteratePrefixes in interface NamespaceResolver

Returns:

an iterator over all the prefixes for which a namespace binding exists, including the zero-length string to represent the null/absent prefix if it is bound

getNamespaceURI

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

Implement the JAXP getNamespaceURI() method in terms of the Saxon-specific methods

Specified by:

getNamespaceURI in interface javax.xml.namespace.NamespaceContext

Parameters:

prefix - a namespace prefix

Returns:

the corresponding URI, if the prefix is bound, or "" otherwise

getPrefix

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

Get the prefix bound to a particular namespace URI, if there is one, or null if not (JAXP method)

Specified by:

getPrefix in interface javax.xml.namespace.NamespaceContext

Parameters:

uri - the namespace URI

Returns:

the prefix bound to the URI if there is one, or null if not

getPrefixes

public java.util.Iterator<java.lang.String> getPrefixes(java.lang.String uri)

Get all the prefixes mapped to a given namespace URI (JAXP method)

Specified by:

getPrefixes in interface javax.xml.namespace.NamespaceContext

Parameters:

uri - the namespace URI

Returns:

an iterator over all the prefixes bound to this namespace URI
