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
.
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:
- The object is not
null
.
- The classes of this and the other object are equal.
- 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.
