VariableCondition	The instantiations of a schemavariable can be restricted on rule scope by attaching conditions on these variables.

Class Summary

Class	Description
AbstractBuiltInRuleApp
AbstractContractRuleApp
AntecTaclet	An AntecTaclet represents a taclet whose find part has to match a top level formula in the antecedent of the sequent.
BlockContractBuiltInRuleApp
BlockContractRule
BlockContractRule.ConditionsAndClausesBuilder
BlockContractRule.GoalsConfigurator
BlockContractRule.Instantiation
BlockContractRule.Instantiator
BlockContractRule.UpdatesBuilder
BlockContractRule.ValidityProgramConstructor
BlockContractRule.VariablesCreatorAndRegistrar
BoundUniquenessChecker	The bound uniqueness checker ensures that schemavariables can be bound at most once in the \find and \assumes part of a taclet.
ContractRuleApp	Represents an application of a contract rule.
DefaultBuiltInRuleApp	this class represents an application of a built in rule application
FindTaclet	An abstract class to represent Taclets with a find part.
IfFormulaInstDirect	Instantiation of an if-formula that has to be proven by an explicit if-goal
IfFormulaInstSeq	Instantiation of an if-formula that is a formula of an existing sequent.
IfFormulaInstSeq.Cache
IfMatchResult
LoopInvariantBuiltInRuleApp	The built in rule app for the loop invariant rule.
MatchConditions	Simple container class containing the information resulting from a Taclet.match-call
NewDependingOn	Deprecated
NewVarcond	variable condition used if a new variable is introduced
NoFindTaclet	Used to implement a Taclet that has no find part.
NoPosTacletApp	A no position taclet application has no position information yet.
NotFreeIn
OneStepSimplifier
OneStepSimplifier.Instantiation
OneStepSimplifier.Protocol
OneStepSimplifier.TermReplacementKey	Instances of this class are used in the Map of OneStepSimplifier#replaceKnown(TermServices, SequentFormula, Map, List, Protocol) to forece the same behavior as in Taclet rules where names of logical variables and TermLabels are ignored.
OneStepSimplifierRuleApp
PosTacletApp	A position taclet application object, contains already the information to which term/formula of the sequent the taclet is attached.
QueryExpand	The QueryExpand rule allows to apply contracts or to symbolically execute a query expression in the logic.
RewriteTaclet	A RewriteTaclet represents a taclet, whose find can be matched against any term in the sequent no matter where it occurs.
RuleKey	Provides a unique key for taclets based on a taclet's name and its taclet options.
RuleSet
SuccTaclet	A SuccTaclet represents a taclet whose find part has to match a top level formula in the succedent of the sequent.
SVNameCorrespondenceCollector	This visitor is used to collect information about schema variable pairs occurring within the same substitution operator within a taclet.
SyntacticalReplaceVisitor
Taclet	Taclets are the DL-extension of schematic theory specific rules.
Taclet.TacletLabelHint	Instances of this class are used as hints to maintain TermLabels.
TacletApp	A TacletApp object contains information required for a concrete application.
TacletApplPart
TacletAttributes
TacletPrefix
TacletSchemaVariableCollector	Collects all schemavariables occurring in the \find, \assumes part or goal description of a taclet.
TacletVariableSVCollector	This class is used to collect all appearing SchemaVariables that are bound in a Taclet.
Trigger
UninstantiatedNoPosTacletApp	A subclass of NoPosTacletApp for the special case of a taclet app without any instantiations.
UseDependencyContractApp
UseDependencyContractRule
UseOperationContractRule	Implements the rule which inserts operation contracts for a method call.
UseOperationContractRule.AnonUpdateData
UseOperationContractRule.Instantiation
VariableConditionAdapter	The variable condition adapter can be used by variable conditions which can either fail or be successful, but which do not create a constraint.
WhileInvariantRule
WhileInvariantRule.AnonUpdateData
WhileInvariantRule.InfFlowData
WhileInvariantRule.Instantiation

Enum Summary

Enum	Description
Taclet.TacletLabelHint.TacletOperation	Defines the possible operations a Taclet performs.
TacletAnnotation	KeY parser can add annotations to taclets during parsing.

Package de.uka.ilkd.key.rule Description

This package contains classes for implementing rules. Most rules are taclet rules, represented by Taclet. The package includes the representation of applications of taclets (TacletApp) and the builders of taclets (de.uka.ilkd.key.rule.TacletBuilder). Besides taclets, there are built-in rules implemented directly in Java.
