Type Parameters:

T - the type of the input argument to the filter

E - the type of the value to use for comparison

All Implemented Interfaces:

ExternalizableLite, PortableObject, Filter<T>, EntryFilter<Object,T>, IndexAwareFilter<Object,T>, QueryRecorderFilter<T>, Serializable

public class GreaterEqualsFilter<T,E extends Comparable<? super E>>
extends GreaterFilter<T,E>
implements IndexAwareFilter<Object,T>

Filter which compares the result of a method invocation with a value for "Greater or Equal" condition. In a case when either result of a method invocation or a value to compare are equal to null, the evaluate test yields false. This approach is equivalent to the way the NULL values are handled by SQL.
