public class MemoryCleanUp
extends Operator

Cleans up unused memory resources. Might be very useful in combination with the MaterializeDataInMemory operator after large preprocessing trees using lot of views or data copies. Internally, this operator simply invokes a garbage collection from the underlying Java programming language.
