Class EntrySetMap

java.lang.Object
java.util.AbstractMap
com.tangosol.util.EntrySetMap

All Implemented Interfaces:

java.util.Map

public class EntrySetMap

extends java.util.AbstractMap

A trivial Map implementation that is based on a specified set of entries. This implementation does not support inserts or updates. Additionally, since almost every operation is implemented by iterating over the underlying entry set, this class is meant to be used only for iterations or small sets of data.

Since:

entrySet

public java.util.Set entrySet()

Description copied from class: java.util.AbstractMap

Returns a set view of the mappings contained in this map. Each element in this set is a Map.Entry. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. (If the map is modified while an iteration over the set is in progress, the results of the iteration are undefined.) The set supports element removal, which removes the corresponding entry from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
