boolean	apply(Collection<EquivalentFragmentSet> fragmentSets, GraknTx tx) Apply the optimisation to the given EquivalentFragmentSets using the given GraknTx.

Method Detail

apply

boolean apply(Collection<EquivalentFragmentSet> fragmentSets,
              GraknTx tx)

Apply the optimisation to the given EquivalentFragmentSets using the given GraknTx.

The strategy may modify the collection. If it does, it will return true, otherwise it will return false.

Parameters:

fragmentSets - a mutable collection of EquivalentFragmentSets

tx - the GraknTx that these EquivalentFragmentSets are going to operate against

Returns:

whether fragmentSets was modified
