Class WellDefinednessMacro

java.lang.Object

de.uka.ilkd.key.macros.AbstractProofMacro

de.uka.ilkd.key.macros.StrategyProofMacro

de.uka.ilkd.key.macros.WellDefinednessMacro

All Implemented Interfaces:

ProofMacro

public class WellDefinednessMacro
extends StrategyProofMacro

This macro resolves the well-definedness transformer, i.e. it applies exactly all applicable rules to resolve the operators WD and wd (which are formula/term transformers). These rules all have the prefix defined in WD_PREFIX. The macro is only applicable for proof obligations created in #WellDefinednessPO and the Well-Definedness branches in #WhileInvariantRule and #BlockContractRule.

getName

public String getName()

Description copied from interface: ProofMacro

Gets the name of this macro. Used as menu entry

Returns:

a non-null constant string

getCategory

public String getCategory()

Description copied from interface: ProofMacro

Gets the category of this macro. Used as name of the menu under which the macro is sorted. Return null if no submenu is to be created.

Returns:

a constant string, or null

getDescription

createStrategy

protected Strategy createStrategy(Proof proof,

Specified by:

createStrategy in class StrategyProofMacro

canApplyTo

public boolean canApplyTo(Proof proof,
                          ImmutableList<Goal> goals,
                          PosInOccurrence posInOcc)

Description copied from class: StrategyProofMacro

Can this macro be applied on the given goals? This method should not make any changes but check if the macro can be applied or not on the given goals. This method may be called from within the GUI thread and be compatible with that fact. This macro can always be applied (does not change anything perhaps) TODO make this only applicable if it has an impact.

Specified by:

canApplyTo in interface ProofMacro

Overrides:

canApplyTo in class StrategyProofMacro

Parameters:

proof - the current Proof (not null)

goals - the goals (not null)

posInOcc - the position in occurrence (may be null)

Returns:

true, if the macro is allowed to be applied
