Methods

Modifier and Type	Method and Description
ConditionalBranch	clone() There is not reason to clone this object since it is stateless.
boolean	equals(Object obj)
ConditionalBranch	getElseBranch()
EvalCondition	getEvalCondition()
Map<String,Declaration>	getInnerDeclarations() It is not possible to declare any new variables, so always return an Empty Map
NamedConsequence	getNamedConsequence()
List<RuleConditionElement>	getNestedElements() It is not possible to nest elements inside a conditional branch, so always return an empty list.
Map<String,Declaration>	getOuterDeclarations() It is not possible to declare and export any variables, so always return an empty map
int	hashCode()
boolean	invokesConsequence(String consequenceName)
boolean	isPatternScopeDelimiter() Returns true in case this RuleConditionElement delimits a pattern visibility scope.
void	readExternal(ObjectInput in)
Declaration	resolveDeclaration(String identifier) Not possible to resolve any declaration, so always return null.

Method Detail

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

clone

public ConditionalBranch clone()

There is not reason to clone this object since it is stateless. So a clone() call will return the instance itself.

Specified by:

clone in interface RuleConditionElement

Specified by:

clone in class ConditionalElement

Returns:

getInnerDeclarations

public Map<String,Declaration> getInnerDeclarations()

It is not possible to declare any new variables, so always return an Empty Map

Specified by:

getInnerDeclarations in interface RuleConditionElement

Returns:

getNestedElements

public List<RuleConditionElement> getNestedElements()

It is not possible to nest elements inside a conditional branch, so always return an empty list.

Specified by:

getNestedElements in interface RuleConditionElement

Returns:

getOuterDeclarations

public Map<String,Declaration> getOuterDeclarations()

It is not possible to declare and export any variables, so always return an empty map

Specified by:

getOuterDeclarations in interface RuleConditionElement

Returns:

resolveDeclaration

public Declaration resolveDeclaration(String identifier)

Not possible to resolve any declaration, so always return null.

Specified by:

resolveDeclaration in interface RuleConditionElement

Returns:

invokesConsequence

public boolean invokesConsequence(String consequenceName)

Specified by:

invokesConsequence in interface NamedConsequenceInvoker

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

isPatternScopeDelimiter

public boolean isPatternScopeDelimiter()

Description copied from interface: RuleConditionElement

Returns true in case this RuleConditionElement delimits a pattern visibility scope. For instance, AND CE is not a scope delimiter, while NOT CE is a scope delimiter

Specified by:

isPatternScopeDelimiter in interface RuleConditionElement

Returns:

getEvalCondition

public EvalCondition getEvalCondition()

getNamedConsequence

public NamedConsequence getNamedConsequence()

getElseBranch

public ConditionalBranch getElseBranch()
