Class SafeSortedMap.ViewMap

java.lang.Object
java.util.AbstractMap
com.tangosol.util.SafeSortedMap.ViewMap

All Implemented Interfaces:

java.util.Map, java.util.SortedMap

Enclosing class:

SafeSortedMap

protected class SafeSortedMap.ViewMap

extends java.util.AbstractMap

implements java.util.SortedMap

ViewMap provides a SortedMap view over a subset of the SafeSortedMap. A ViewMap may have an inclusive lower and/or an exclusive upper bound.

For example, a ViewMap defined on an SafeSortedMap of Integer keys with lower bound 3 and upper bound 7 would contain any keys in the underlying SafeSortedMap in the range [3, 7).

Nested Class Summary

protected class	SafeSortedMap.ViewMap.EntryIterator An Iterator over the Entries backed by this ViewMap.
protected class	SafeSortedMap.ViewMap.EntrySet A Set of Entries backed by this ViewMap.
