Filters of filters

There are another set of filters that receive as parameter one or several filters and act on them. The list of composed filters in the current GAMOS version is the following:

• GmORFilter: returns true if one of the filters returns true

• GmXORFilter: returns true if one and only one of the filters returns true

• GmANDFilter: returns true if every filter returns true

• GmParentFilter: apply a filter to the parent track instead of the current track

• GmHistoryFilter: returns true if all the filters in one of the previous steps, or the beginning of track, have returned true (i.e. it does not check again the current step if it was accepted in a previous one or begin of track)

• GmHistoryAllFilter: returns true if all the filters in all previous steps, and the beginning of track have returned true (i.e. it does not check again the current step if it was rejected in a previous one or begin of track)

• GmHistoryOrAncestorsFilter: behaves similarly as the GmHistoryFilter but also returns true if the condition is fulfilled by any step or track of the ancestors of the current track

• GmHistoryAncestorsAllFilter: behaves similarly as the GmHistoryAllFilter but also returns false if the condition is not fulfilled by any step or track of the ancestors of the current track

• GmAncestorsFilter: behaves similarly as the GmHistoryOrAncestorsFilter but it does not check if a previous step has passed the filter

• GmOnAllSecondariesFilter: makes the list of filters act of the secondary tracks created in the step, or in the whole track; returns true if all secondary tracks created accept all the filters.

• GmOn1SecondaryFilter: makes the list of filters act of the secondary tracks created in the step, or in the whole track; returns true if any of the secondary tracks created accept all the filters.

• GmOnSecondaryFilter: this filter is designed to work with GmSecondaryTrackData users. The filter will be applied not the current step or track but to the secondary tracks created.

• GmInverseFilter: returns the opposite that the filter it receives as only parameter
