Type Parameters:

T - the type of the input argument to the filter

E - the type of value to use for comparison

All Implemented Interfaces:

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

public class LessEqualsFilter<T,E extends Comparable<? super E>>
extends LessFilter<T,E>
implements IndexAwareFilter<Object,T>

Filter which compares the result of a method invocation with a value for "Less or Equals" 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.

extractor - the ValueExtractor to use by this filter

value - the object to compare the result with

LessEqualsFilter

public LessEqualsFilter(String sMethod,
                        E value)

Construct a LessEqualsFilter for testing "Less or Equals" condition.
