Class 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.

      • 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
