Constructor Detail

MapProxy

public MapProxy(B base)

Constructs a new proxy of the specified object.

Parameters:

base - the underlying object.

Throws:

NullPointerException - if the specified object is null.

Method Detail

equals

public boolean equals(Object o)

Description copied from class: ObjectProxy

Indicates whether some other object is "equal to" this one. This implementation checks three conditions:

1. The object is not null.
2. The classes of this and the other object are equal.
3. The base objects are equal.

Specified by:

equals in interface Map<K,V>

Overrides:

equals in class ObjectProxy<B extends Map<K,V>>

Parameters:

o - the reference object with which to compare

Returns:

true if this object equals the specified object.

size

public int size()

Specified by:

size in interface Map<K,V>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K,V>

containsKey

             V value)

Specified by:
