Class Not

    java.lang.Object
      cascading.operation.BaseOperation
          cascading.operation.filter.Not

All Implemented Interfaces:
  DeclaresResults, Filter, Operation, Traceable, Serializable

    public class Not

extends BaseOperation
implements Filter

Class Not is a `Filter` class that will logically 'not' (negation) the results of the constructor provided Filter instance.

Logically, if `Filter.isRemove(cascading.flow.FlowProcess, cascading.operation.FilterCall)` returns `true` for the given instance, this filter will return the opposite, `false`.
