A namespace manager than can provide namespaces for prefixes. Note that the empty string always points to the default namespace if there is a default namespace.

Method Summary

boolean	containsPrefixMapping(java.lang.String prefix) Determines if this manager knows about a given namespace prefix and it contains a (non-null) mapping for the prefix.
java.lang.String	getDefaultNamespace() Gets the default namespace.
java.lang.String	getNamespace(java.lang.String prefix) Gets the namespace that is bound to a particular prefix.
java.util.Map<java.lang.String,java.lang.String>	getNamespaceMap() Gets a map that maps prefixes to namespaces.
java.net.URI	getURI(java.lang.String curi) Gets the URI for a given CURI.

Method Detail

getDefaultNamespace

java.lang.String getDefaultNamespace()

Gets the default namespace.

Returns:

The default namespace, or null if there is no default namespace.

containsPrefixMapping

boolean containsPrefixMapping(java.lang.String prefix)

Determines if this manager knows about a given namespace prefix and it contains a (non-null) mapping for the prefix.

Parameters:

prefix - The prefix to be tested for.

Returns:

true if the manager knows about this prefix and there is a non-null mapping for this prefix.

getNamespace

java.lang.String getNamespace(java.lang.String prefix)

Gets the namespace that is bound to a particular prefix. Note that specifying the empty string corresponds to requesting the default namespace and will return the same result as a call to the getDefaultNamespace() method.

Parameters:

prefix - The namespace prefix. A string that represents a namespace prefix of the namespace to be retrieved. Note that specifying the empty string is the same as asking for the default namespace (see the getDefaultNamespace() method).

Returns:

The namespace, or null if there is no namespace bound to this prefix, or the prefix doesn't exist.

getNamespaceMap

java.util.Map<java.lang.String,java.lang.String> getNamespaceMap()

Gets a map that maps prefixes to namespaces.

Returns:

The map of prefixes to namespaces. Note that modifying the contents of this map will not change the prefix - namespace mappings

getURI

java.net.URI getURI(java.lang.String curi)

Gets the URI for a given CURI. The CURI must have a namespace prefix that is registered with this namespace manager, or a runtime exception will be thrown.

Parameters:

curi - The CURI

Returns:

The full URI.
