Class LazyUnionMap<K,V>

java.lang.Object

com.android.ide.common.util.LazyUnionMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

public class LazyUnionMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>

Read-only map that delegates read operations to two disjoint maps.

The set of keys of both maps needs to be disjoint. This class is meant to "join" two disjoint maps in a single object, not to implement an overlay.
