Constructor Details

EvaluatorBasedRestrictionDescr

public EvaluatorBasedRestrictionDescr()

Creates a new EvaluatorBasedRestriction

EvaluatorBasedRestrictionDescr

public EvaluatorBasedRestrictionDescr(String evaluator,
 boolean isNegated,
 String parameterText)

Creates a new EvaluatorBasedRestriction

Parameters:

evaluator - the evaluator ID to be used in this restriction

isNegated - true if the evaluator is boolean negated

parameterText - the parameter text, in case there is any. null otherwise.

EvaluatorBasedRestrictionDescr

public EvaluatorBasedRestrictionDescr(String evaluator,
 boolean isNegated,
 List<String> parameters)

Creates a new EvaluatorBasedRestriction

Parameters:

evaluator - the evaluator ID to be used in this restriction

isNegated - true if the evaluator is boolean negated

parameters - the list of parameters texts, in case there is any. null otherwise.

Method Details

getEvaluator

public String getEvaluator()

Returns the evaluator ID for this restriction

Returns:

isNegated

public boolean isNegated()

Returns true if this evaluator is boolean negated. Example: "contains" is boolean negated if you want to check the elements that are not contained ("not contains")

Overrides:

isNegated in class BaseDescr

Returns:

the negated

getParameterText

public String getParameterText()

In case there is any parameter text, this method returns it. Returns null otherwise. A parameter text is evaluator parameters like "after[1,10]". In the previous example, the parameter text will be "1,10".

Returns:

the parameterText

getParameters

public List<String> getParameters()

setParameters

public void setParameters(List<String> parameters)

setEvaluator

public void setEvaluator(String evaluator)

Sets the evaluator ID for this restriction

setNegated

public void setNegated(boolean negated)

Sets if this evaluator is negated. Example: "contains" is boolean negated if you want to check the elements that are not contained ("not contains")

Parameters:

negated - the negated

toString

public String toString()

Overrides:

toString in class Object
