CLbtTriggerFilterComposite Class Reference

class CLbtTriggerFilterComposite : public CLbtTriggerFilterBase

Class representing a composite filter. This class is used to combine multiple filters.

All filters combined in this class will be applied when listing triggers. Currently only ECompositionTypeAnd is supported to be the composition type. In this case, only those triggers that fulfill the criteria specified by all the filters will be retrieved.
