Enumeration FilterItemInterfaceSignal

The FilterItemInterfaceSignal lists all the signals that may be sent by the abstract FilterItemInterface.

These signals are emitted by the abstract FilterItemInterface when it is modified.

There is no way to know when the abstract FilterItemInterface is ready : the abstract FilterItemInterface is contained inside a WorkingSetInterface that notifies when it is ready. As such, there is no way to get the part instances or geometric instances that are included in such a FilterItemInterface.

The FilterItemInterface may fire the following signals :

• FilterOperatorChanged : the GroupOperator of the FilterItemInterface (FilterItemInterface.setFilterOperator) has changed.
• FilterInvertedChanged : the inverted status of the FilterItemInterface (FilterItemInterface.setInverted) has been changed.
• FilterEnabledChanged : the enabled state of the FilterItemInterface (FilterItemInterface.setEnabled) has been changed.
• FilterDataChanged : the specific data of the filter that inherits FilterItemInterface has been changed (e.g. FilterItemInterface.fromJSON, FilterAABBInterface.setAABB, FilterAttributeInterface.setAttributeName, etc ...).
• FilterChanged : the abstract FilterItemInterface has changed, other signals may be sent before (e.g. FilterOperatorChanged), in this case the FilterChanged signal is always the last to be sent.

{
    // output a fancy message when filter changes
    console.log('filter has changed');
    // and remove the listener
    lFilter.removeEventListenerById(lCallbackId);
});
