Class IntervalFilter

java.lang.Object
  org.jcreme.filters.IntervalFilter

All Implemented Interfaces:

java.lang.Cloneable, Filter, java.io.Serializable

Direct Known Subclasses:

DateIntervalFilter, DoubleIntervalFilter

public class IntervalFilter

extends java.lang.Object

implements Filter, java.io.Serializable, java.lang.Cloneable

This filter enables to perform an AND between two OrderFilters. Therefore it models an interval of values. This class should be overriden to provide a stronger typing. No accessor methods are provided here so that the implementing classes can provide a typed method.

lowerFilter - the lower filter for the interval.

upperFilter - the upper filter for the interval.

Method Detail

setLowerFilter

protected void setLowerFilter(OrderFilter filter)

Parameters:

filter - a filter to restrict the current interval.

getLowerFilterInternal

protected OrderFilter getLowerFilterInternal()

Returns:

the lower filter of the interval.

setUpperFilter

protected void setUpperFilter(OrderFilter filter)

Parameters:

filter - a filter to restrict the current interval.

getUpperFilterInternal

protected OrderFilter getUpperFilterInternal()

Returns:

the upper filter of the interval.

accept

public boolean accept(java.lang.Object obj)

This is the actual filtering method.

Specified by:

accept in interface Filter

Parameters:

obj - the Object to filter.

Returns:

true if the given object satisfies all the conditions of the filter.

clone

public java.lang.Object clone()

Description copied from interface: Filter

This forces override of the Object class clone method. it makes a deep copy so a change in a subfilter does not affect the cloned version.
