Uses of Projection in com.hazelcast.client.proxy

Methods in com.hazelcast.client.proxy with parameters of type Projection

Modifier and Type	Method and Description
<R> Iterator<R>	ClientMapProxy.iterator(int fetchSize, int partitionId, Projection<Map.Entry<K,V>,R> projection, Predicate<K,V> predicate) Returns an iterator for iterating the result of the projection on entries in the partitionId which satisfy the predicate.
