public List<LocationVariable> getHeapContext()

Specified by:

getHeapContext in interface IBuiltInRuleApp

Overrides:

getHeapContext in class AbstractBuiltInRuleApp

replacePos

public BlockContractBuiltInRuleApp replacePos(PosInOccurrence newOccurrence)

Specified by:

replacePos in interface IBuiltInRuleApp

Specified by:

complete

public boolean complete()

Description copied from class: AbstractBuiltInRuleApp

returns true if all variables are instantiated

Specified by:

complete in interface RuleApp

Overrides:

complete in class AbstractBuiltInRuleApp

Returns:

true if all variables are instantiated

isSufficientlyComplete

public boolean isSufficientlyComplete()

Description copied from interface: IBuiltInRuleApp

returns true if tryToInstantiate may be able to complete the app

Specified by:

isSufficientlyComplete in interface IBuiltInRuleApp

Overrides:

isSufficientlyComplete in class AbstractBuiltInRuleApp

Returns:

tryToInstantiate

public BlockContractBuiltInRuleApp tryToInstantiate(Goal goal)

Description copied from interface: IBuiltInRuleApp

Tries to complete the rule application from the available information. Attention: Do neither add GUI code to the rules nor use this method directly Instead ask the implementation of the UserInterfaceControl to complete a built-in rule. Returns a complete app only if there is exactly one contract. If you want a complete app for combined contracts, use forceInstantiate instead. For an example implementation see e.g. UseOperationContractRule or UseDependencyContractRule.

Specified by:

tryToInstantiate in interface IBuiltInRuleApp

Specified by:

tryToInstantiate in class AbstractBuiltInRuleApp
