Constructor Detail

MatchImpl

public MatchImpl(Rule rule)

Default constructor.

Parameters:

rule - Rule to be matched.

MatchImpl

public MatchImpl(Rule rule,
                 boolean isResultMatch)

Constructor.

Parameters:

rule - The rule that this match is used for.

isResultMatch - Determines whether this is a result match.

MatchImpl

public MatchImpl(Assignment assignment,
                 boolean isResultMatch)

Constructor.

Parameters:

assignment - The assignment or match to be copied.

isResultMatch - Determines whether this is a result match.

Method Detail

setUnit

protected void setUnit(Unit unit)

Overrides:

setUnit in class AssignmentImpl

getRule

public Rule getRule()

Description copied from interface: Match

Get the rule that this match is used for.

Specified by:

getRule in interface Match

Returns:

The rule.

getNodeTarget

public EObject getNodeTarget(Node node)

Description copied from interface: Match

Get the match target for a node.

Specified by:

getNodeTarget in interface Match

Parameters:

node - The node.

Returns:

The matched target object.

setNodeTarget

public void setNodeTarget(Node node,
                          EObject target)

Description copied from interface: Match

Set the match target for a node.

Specified by:

setNodeTarget in interface Match

Parameters:

node - The node.

target - The match target.

setParameterValue

public void setParameterValue(Parameter param,
                              Object value)

Description copied from interface: Assignment

Set the assigned value for a parameter.

Specified by:

setParameterValue in interface Assignment

Overrides:

setParameterValue in class AssignmentImpl

Parameters:

param - The parameter.

value - The value to be assigned with the parameter.

getNodeTargets

public List<EObject> getNodeTargets()

Description copied from interface: Match

Get all node targets of this match.

Specified by:

getNodeTargets in interface Match

Specified by:

overlapsWith in interface Match

Parameters:

match - A second match to check against.

Description copied from interface: Match

Checks whether this match is complete, whether the typing of the matched objects is correct with respect to the node types, and whether all edges are present.

Specified by:

isValid in interface Match

Returns:

true if the match is valid.

Overrides:

equals in class AssignmentImpl

toString

public String toString()

Overrides:

toString in class AssignmentImpl

toStringWithIndent

protected String toStringWithIndent(String indent)

Overrides:

toStringWithIndent in class AssignmentImpl
