                                      boolean isNegated,
                                      List<String> parameters)

Method Detail

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")

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
