applyReplacewith

protected abstract void applyReplacewith(TacletGoalTemplate gt,
                                         TermLabelState termLabelState,

                                         Services services)

applies the replacewith-expression of taclet goal descriptions

Parameters:

gt - the TacletGoalTemplate used to get the taclet's replacewith-expression

termLabelState - The TermLabelState of the current rule application.

currentSequent - the SequentChangeInfo which is the current (intermediate) result of applying the taclet

posOfFind - the PosInOccurrence belonging to the find expression

matchCond - the MatchConditions with all required instantiations

goal - the Goal on which the taclet is applied

ruleApp - the TacletApp describing the current ongoing taclet application

services - the Services encapsulating all Java model information

applyAdd

protected abstract void applyAdd(Sequent add,
                                 TermLabelState termLabelState,
                                 SequentChangeInfo currentSequent,
                                 PosInOccurrence posOfFind,
                                 MatchConditions matchCond,
                                 Goal goal,
                                 RuleApp ruleApp,
                                 Services services)

applies the add-expressions of taclet goal descriptions

Parameters:

add - the Sequent with the uninstantiated SequentFormula's to be added to the goal's sequent

termLabelState - The TermLabelState of the current rule application.

currentSequent - the SequentChangeInfo which is the current (intermediate) result of applying the taclet

posOfFind - the PosInOccurrence providing the position information where the match took place (it will be tried to add the new formulas close to that position)

matchCond - the MatchConditions with all required instantiations

ruleApp - the TacletApp describing the current ongoing taclet application

services - the Services encapsulating all Java model information

apply

public final ImmutableList<Goal> apply(Goal goal,
                                       Services services,
                                       RuleApp ruleApp)

the rule is applied on the given goal using the information of rule application.

Specified by:

apply in interface RuleExecutor

Specified by:

apply in class TacletExecutor<TacletKind extends FindTaclet>

Parameters:

goal - the goal that the rule application should refer to.

services - the Services encapsulating all java information

ruleApp - the taclet application that is executed.

Returns:

List of the goals created by the rule which have to be proved. If this is a close-goal-taclet ( this.closeGoal () ), the first goal of the return list is the goal that should be closed (with the constraint this taclet is applied under).
