Description copied from class: BinaryTacletAppFeature

Compute whether the result of the feature is zero (true) or infinity (false)

Specified by:

filter in class BinaryTacletAppFeature

Parameters:

app - the TacletApp

pos - position where app is to be applied

goal - the goal on which app is to be applied

Returns:

true iff the the result of the feature is supposed to be zero.
