Class ExcludeFilter

Object

ExcludeFilter

All Implemented Interfaces:

Serializable, Filter

public final class ExcludeFilter
extends Object
implements Filter, Serializable

Indicating "filter all", evaluates to false. This is a placeholder filter intended to be used in data structuring definition.

• EXCLUDE or Filter ==> Filter
• EXCLUDE and Filter ==> EXCLUDE
• EXCLUDE ==> INCLUDE

The above does imply that the AND opperator can short circuit on encountering ALL.
