Class SafeSortedMap.ViewMap

java.lang.Object

java.util.AbstractMap

com.tangosol.util.SafeSortedMap.ViewMap

All Implemented Interfaces:

Map, SortedMap

Enclosing class:

SafeSortedMap

protected class SafeSortedMap.ViewMap
extends AbstractMap
implements 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).
