Method Details

parameterChanged

public void parameterChanged(String parameterName)

Description copied from interface: ParameterListener

Called, when a parameter has changed. The listener could only react if the parameter name is relevant. Or the listener can just read all parameters again.

Specified by:

parameterChanged in interface ParameterListener

Parameters:

parameterName - the name of the parameter that has changed

getValue

public VALUETYPE getValue(PARAMTYPE p)

Description copied from interface: SwtParameterValueProcessor

Return the value for Parameter p

Specified by:

getValue in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>

setValue

public boolean setValue(PARAMTYPE p,
 VALUETYPE value)

Description copied from interface: SwtParameterValueProcessor

New value for Parameter p. Handle things like storing value.

Specified by:

setValue in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>

Returns:

Whether the value changed from stored value. Returning true will trigger change listeners, and typically refresh UI controls

isDefaultValue

public boolean isDefaultValue(PARAMTYPE p)

Description copied from interface: SwtParameterValueProcessor

Whether the Parameter is currently set to the default value. This may be used to enable ui related to reseting value

Specified by:

isDefaultValue in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>

getDefaultValue

public VALUETYPE getDefaultValue(PARAMTYPE p)

Description copied from interface: SwtParameterValueProcessor

Return the default value.
This may be used to enable ui related to reseting value, or to show the default value to the user

Specified by:

getDefaultValue in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>

resetToDefault

public boolean resetToDefault(PARAMTYPE p)

Description copied from interface: SwtParameterValueProcessor

Reset key to default value

Specified by:

resetToDefault in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>

Returns:

Whether the value was reset. Returning true will trigger change listeners, and typically refresh UI controls

dispose

public void dispose(PARAMTYPE p)

Description copied from interface: SwtParameterValueProcessor

Clean up after yourself, yo

Specified by:

dispose in interface SwtParameterValueProcessor<PARAMTYPE extends SwtParameter<VALUETYPE>, VALUETYPE>
