Constructor Detail

RuleApplicationImpl

public RuleApplicationImpl(Engine engine)

Default constructor.

Parameters:

engine - Engine to be used.

RuleApplicationImpl

public RuleApplicationImpl(Engine engine,
                           EGraph graph,
                           Rule rule,
                           Assignment partialMatch)

Default constructor.

Parameters:

engine - Engine to be used.

graph - Object graph to be transformed.

rule - Rule to be applied.

partialMatch - Partial match or assignment.

Method Detail

execute

public boolean execute(ApplicationMonitor monitor)

Description copied from interface: UnitApplication

Execute this unit application.

Specified by:

execute in interface UnitApplication

Parameters:

monitor - The application monitor or null.

Returns:

true if the unit was successfully applied.

undo

public boolean undo(ApplicationMonitor monitor)

Description copied from interface: UnitApplication

Undo this unit application. This restores the original model as it was before calling #execute().

Specified by:

undo in interface UnitApplication

Parameters:

monitor - The application monitor or null.

Returns:

true if the unit was successfully undone.

redo

public boolean redo(ApplicationMonitor monitor)

Description copied from interface: UnitApplication

Redo this unit application. This method can be invoked after #undo() has been invoked. The effect is that the unit is executed again.

Specified by:

redo in interface UnitApplication

Parameters:

monitor - The application monitor or null.

Returns:

true if the unit was successfully redone.

getRule

public Rule getRule()

Description copied from interface: RuleApplication

Get the rule to be applied.

Specified by:

getRule in interface RuleApplication

Returns:

The rule to be applied.

setRule

public void setRule(Rule rule)

Description copied from interface: RuleApplication

Set the rule to be applied.

Specified by:

setRule in interface RuleApplication

Parameters:

rule - The rule to be applied.

setUnit

public void setUnit(Unit unit)

Description copied from interface: UnitApplication

Set the unit to be applied.

Specified by:

setUnit in interface UnitApplication

Overrides:

setUnit in class AbstractApplicationImpl

Parameters:

unit - The transformation unit.

getAssignment

public Assignment getAssignment()

Description copied from interface: UnitApplication

Get the parameter assignment to be used.

Specified by:

getAssignment in interface UnitApplication

Returns:

The parameter assignment.

setAssignment

public void setAssignment(Assignment assignment)

Description copied from interface: UnitApplication

Set the parameter assignment to be used.

Specified by:

setAssignment in interface UnitApplication

Parameters:

assignment - The parameter assignment.

getResultParameterValue

public Object getResultParameterValue(String paramName)

Description copied from interface: UnitApplication

Get the value assigned to a parameter. This is a convenience method to directly access the result assignment of this unit. This is possible only if the unit is set and the unit is applied.

Specified by:

getResultParameterValue in interface UnitApplication

Parameters:

paramName - The name of the parameter.

Returns:

The assigned result value or null.

setParameterValue

public void setParameterValue(String paramName,
                              Object value)

Description copied from interface: UnitApplication

Set the assigned value for a parameter. This is a convenience method to directly access the assignment of this unit. This is possible only if the unit is set.

Specified by:

setParameterValue in interface UnitApplication

Parameters:

paramName - The name of the parameter.

value - The value to be assigned with the parameter.

getPartialMatch

public Match getPartialMatch()

Description copied from interface: RuleApplication

Get the partial match to be used.

Specified by:

getPartialMatch in interface RuleApplication

Returns:

The partial match.

setPartialMatch

public void setPartialMatch(Match partialMatch)

Description copied from interface: RuleApplication

Set the partial match to be used.

Specified by:

setPartialMatch in interface RuleApplication

Parameters:

Specified by:

getCompleteMatch in interface RuleApplication

Returns:

The complete match.

setCompleteMatch

public void setCompleteMatch(Match completeMatch)

Description copied from interface: RuleApplication

Set the complete match to be used. If it is set to null, the complete match will be derived from the partial match.

Specified by:

setCompleteMatch in interface RuleApplication

Parameters:

completeMatch - The complete match (can be null).

getResultMatch

public Match getResultMatch()

Description copied from interface: RuleApplication

Get the match for the result of the transformation (after the unit has been applied).

Specified by:

getResultMatch in interface RuleApplication

Returns:

The match for the result.

getResultAssignment

public Assignment getResultAssignment()

Description copied from interface: UnitApplication

Get the parameter assignment for the result.

Specified by:

getResultAssignment in interface UnitApplication
