Class NamespaceDeltaMap

java.lang.Object

net.sf.saxon.om.NamespaceMap

net.sf.saxon.om.NamespaceDeltaMap

All Implemented Interfaces:

java.lang.Iterable<NamespaceBinding>, NamespaceBindingSet, NamespaceResolver

public class NamespaceDeltaMap
extends NamespaceMap
implements NamespaceBindingSet, NamespaceResolver

Holds a set of namespace bindings as a simple immutable map from prefixes to URIs.

A NamespaceMap never physically contains a binding for the XML namespace, but some interfaces behave as if it did.

The map may or may not contain a binding for the default namespace, represented by the prefix "" (zero-length string)

The map must not contain any namespace undeclarations: that is, the namespace will never be "" (zero-length string)

Method Detail

emptyMap

public static NamespaceDeltaMap emptyMap()

Get a namespace map containing no namespace bindings

Returns:

an empty namespace map

newInstance

protected NamespaceMap newInstance()

Overrides:

newInstance in class NamespaceMap

allowsNamespaceUndeclarations

public boolean allowsNamespaceUndeclarations()

Overrides:

allowsNamespaceUndeclarations in class NamespaceMap

put

public NamespaceDeltaMap put(java.lang.String prefix,
                             java.lang.String uri)

Description copied from class: NamespaceMap

Add a new entry to the map, or replace an existing entry. An attempt to add a binding of the "xml" prefix to the XML namespace is silently ignored.

Overrides:

put in class NamespaceMap

Parameters:

prefix - the prefix whose entry is to be added or replaced. May be zero-length to represent the default namespace

uri - the URI to be associated with this prefix; if zero-length, any existing mapping for the prefix is removed.

Returns:

a new map containing the added or replaced entry (or this map, unchanged, if the prefix-uri mapping was already present in the old map).

remove

public NamespaceDeltaMap remove(java.lang.String prefix)

Description copied from class: NamespaceMap

Remove an entry from the map

Overrides:

remove in class NamespaceMap

Parameters:

prefix - the entry to be removed from the map

Returns:

a new map in which the relevant entry has been removed, or this map (unchanged) if the requested entry was not present
