java.lang.Object

com.luciad.lucy.util.TLcyModelObjectFilter

All Implemented Interfaces:

ILcdChangeSource, ILcdDynamicFilter, ILcdFilter, Serializable, Predicate

public class TLcyModelObjectFilter
extends Object
implements ILcdDynamicFilter

An implementation of ILcdFilter that is able to filter out specific objects of an ILcdIntegerIndexed. The set of accepted objects can be changed using changeFilter(Object, boolean) or changeFilterAllObjects(boolean).

This filter is used by default by the table view. Setting such a filter on your layer will allow the TableView to directly adjust your filter.

Since:

11.0

Constructor Detail

TLcyModelObjectFilter

public TLcyModelObjectFilter(ILcdIntegerIndexedModel aModel)

Create a new filter

Parameters:

aModel - The model of aLayer. Must be an ILcdIntegerIndexedModel

Method Detail

addChangeListener

public void addChangeListener(ILcdChangeListener aChangeListener)

Adds the given ILcdChangeListener. This listener is informed whenever this ILcdFilter has changed. That is, when the accept method returns a different value for at least one of the objects of the associated ILcdIntegerIndexedModel.

Specified by:

addChangeListener in interface ILcdChangeSource

Parameters:

aChangeListener - The listener to add.

See Also:

ILcdChangeSource.removeChangeListener(ILcdChangeListener), ALcdWeakChangeListener

removeChangeListener

public void removeChangeListener(ILcdChangeListener aChangeListener)

Removes the given ILcdChangeListener

Specified by:

removeChangeListener in interface ILcdChangeSource

Parameters:

aChangeListener - The listener to remove.

fireChangeEvent

protected void fireChangeEvent(TLcdChangeEvent aEvent)

Fires the given TLcdChangeEvent to all listeners.

Parameters:

aEvent - The event to fire.

getModel

public ILcdIntegerIndexedModel getModel()

Returns the associated ILcdIntegerIndexedModel for which this ILcdFilter works.

Returns:

the associated ILcdIntegerIndexedModel for which this ILcdFilter works.

setModel

public void setModel(ILcdIntegerIndexedModel aModel)

Sets the ILcdIntegerIndexedModel for which this ILcdFilter works.

Parameters:

aModel - The model for which this filter will work.

changeFilter

public void changeFilter(Object aObject,
                         boolean aAccept)

Sets whether or not an object should be accepted (e.g., visible) by this ILcdFilter.

Parameters:

aObject - The object of which to change the accepted state, must be an element of the associated ILcdIntegerIndexedModel.

aAccept - true if the object should be accepted, false otherwise.

See Also:

changeFilter(java.util.List, boolean)

changeFilter

public void changeFilter(List<Object> aObjectList,
                         boolean aAccept)

Sets whether or not an object/multiple objects should be accepted (e.g., visible) by this ILcdFilter

Parameters:

aObjectList - A List of objects of which to change the accepted state. Every Object in the list must be an element of the associated ILcdIntegerIndexedModel.

aAccept - true if each of the Objects in aObjectList must be accepted, false otherwise

See Also:

changeFilter(Object, boolean)

changeFilterAllObjects

public void changeFilterAllObjects(boolean aAccept)

Changes the accepted state (e.g., the visibility) of all the objects in the ILcdModel.

Parameters:

aAccept - true if all model objects should be accepted, false otherwise.

accept

public boolean accept(Object aObject)

Description copied from interface: ILcdFilter

Tests if a given object passes the filter or not. The actual test condition is specified by the implementation of this interface.

Specified by:

accept in interface ILcdFilter

Parameters:

aObject - the object to be tested by the filter.

Returns:

true if the object passes the filter, false otherwise.

getNumberOfAcceptedObjects

public int getNumberOfAcceptedObjects()

Returns the number of domain objects that are accepted by this filter.

Returns:

The number of accepted domain objects. Is always between 0 and getModel().size().
