Class QNameMap<V>

public final class QNameMap<V> extends Object

Map keyed by QName. This specialized map allows a look up operation without constructing a new QName instance, for a performance reason. This Map assumes that both namespace URI and local name are String#intern() interned.

Since: JAXB 2.0

get

public V get(String nsUri, String localPart)
Returns the value to which the specified keys are mapped in this QNameMap, or null if the map contains no mapping for this key.

Parameters: nsUri the namespaceUri key whose associated value is to be returned. localPart the localPart key whose associated value is to be returned.

Returns: the value to which this map maps the specified set of keya, or null if the map contains no mapping for this set of keys.
