Modifier and Type	Method	Description
OperatorType	getComparisonOperator()
Set<Parameter>	getDependentParameters()	Return the set of parameters which are required in order to evaluate the match criteria.
ParameterInstanceRef	getlValueRef()
Object	getrValueRef()
boolean	isMet(CriteriaEvaluator evaluator)	Return true if the condition matches
void	resolveValueType()	Called when the type of the parameter used for comparison is known, so we have to find the value from stringValue that we can compare to it

Method Detail

resolveValueType

public void resolveValueType()

Called when the type of the parameter used for comparison is known, so we have to find the value from stringValue that we can compare to it

isMet

public boolean isMet(CriteriaEvaluator evaluator)

Description copied from interface: MatchCriteria

Return true if the condition matches

Specified by:

isMet in interface MatchCriteria

Returns:

getDependentParameters

public Set<Parameter> getDependentParameters()

Description copied from interface: MatchCriteria

Return the set of parameters which are required in order to evaluate the match criteria. If no parameter is required, return an empty set.

Specified by:

getDependentParameters in interface MatchCriteria

Returns:

toExpressionString

public String toExpressionString()

Specified by:

toExpressionString in interface MatchCriteria

toString

public String toString()

Overrides:

toString in class Object

getlValueRef

public ParameterInstanceRef getlValueRef()

getrValueRef

public Object getrValueRef()

Returns:

right value reference - could be itself an ParameterInstanceRef

getComparisonOperator

public OperatorType getComparisonOperator()
