All Implemented Interfaces:

Serializable

public class DynamicFixedValuesParameterDefinition

Method Detail

allowZeroFixedValues

protected boolean allowZeroFixedValues()

Returns true meaning this class allows the parameter definition's allowed values to be empty. This is because this class allows that list of allowed values to be modified dynamically at runtime. You could therefore instantiate this parameter definition with zero allowed values and later on add to that list (in the case when the allowed values aren't known until after this object has been instantiated).

Overrides:

allowZeroFixedValues in class FixedValuesParameterDefinition

Returns:

this method implementation always returns false

See Also:

FixedValuesParameterDefinition.allowZeroFixedValues()

setAllowedValues

public void setAllowedValues(List<Object> newAllowedValues)
                      throws IllegalArgumentException

This class allows the parameter definition's fixed values to be changed at runtime via this method (unlike its parent class).

Overrides:

setAllowedValues in class FixedValuesParameterDefinition

Parameters:

newAllowedValues - the new list of allowed values

Throws:

IllegalArgumentException - if failed to convert the values to the parameter definition's type or allowedValues was null or empty and this parameter definition object does not accept that (see FixedValuesParameterDefinition.allowZeroFixedValues()).

FixedValuesParameterDefinition.setAllowedValues(List)
