  +--oracle.cabo.share.util.NamespaceMap

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

BindableNamespaceMap

public class NamespaceMap

extends java.lang.Object

implements java.lang.Cloneable

Implements a map between a namespace+key and a value. This unsynchronized class is optimized for a small number of namespaces.

Constructor Summary

NamespaceMap()
Creates a NamespaceMap, using a default size for the number of values per namespace.

NamespaceMap(int defaultSize)
Creates a NamespaceMap.

Method Summary

void	clear() clears all bindings for all namespaces.
void	clear(java.lang.String namespace) clears all keys from a namespace.
java.lang.Object	clone() Returns a clone of the NamespaceMap
java.lang.Object	get(java.lang.String namespace, java.lang.Object key) Returns the stored object.
java.util.Enumeration	getKeysEnumeration(java.lang.String namespace) Returns an Enumeration over all of the keys for a particular namespace.
java.util.Enumeration	getNamespaceEnumeration() Returns an Enumeration over all the namespaces added to the map.
java.util.Enumeration	getValueEnumeration() Returns an Enumeration over all the values added to the map.
java.util.Enumeration	getValueEnumeration(java.lang.String namespace) Returns an Enumeration over all of the values for a particular namespace.
void	put(java.lang.String namespace, java.lang.Object key, java.lang.Object value) associates a value with a namespace and a key

NamespaceMap

public NamespaceMap(int defaultSize)

Creates a NamespaceMap.

Parameters:

defaultSize - the default size of each per-namespace storage.

Method Detail

put

public void put(java.lang.String namespace,
                java.lang.Object key,
                java.lang.Object value)

associates a value with a namespace and a key

Parameters:

namespace - namespace of the value

key - the key to associate the value with

value - the value to associate with the key.

get

                            java.lang.Object key)

Returns the stored object.

Parameters:

namespace - the namespace to search.

key - the key to search the namespace for.

Returns:

null if such a namespace/key does not exist. else returns the associated value.

remove

public java.lang.Object remove(java.lang.String namespace,
                               java.lang.Object key)

Parameters:

namespace - the namespace to search.

key - the key to search the namespace for.

Returns:

the associated value, or null if the namespace/key does not exist.
