java.lang.Object org.eclipse.ocl.LazyExtentMap<CLS,E>
public abstract class LazyExtentMap<CLS,E>
A self-populating map that lazily creates the extent of a class when asked for it.
Note that this implementation violates the contract of the
Map
API as follows:
Map.entrySet()
method does not return entries
for any keys that have not already been queried via the
Map.get(java.lang.Object)
methodMap.keySet()
and Map.values()
methods also are not complete
See the Environment
class for a description of the
generic type parameters of this class.
