                                                                                  Double fieldValue,

                                                                           throws FieldHandlingException

Specified by:

handle in interface TypeHandler<Double,FieldUpdateEvent<Double>,ReflectionFormBuilder,DoublePanel>

Parameters:

type - the Type to be handled

fieldValue - the value of the field or the nested generic property

fieldName - the name of the field (the same for nested generics)

declaringClass - the class declaring the field

updateListener - an FieldUpdateListener to notify on updates

reflectionFormBuilder - a ReflectionFormBuilder used for recursion

Returns:

a Pair of the handling result and the generating ComponentResettable. The latter reference can be used to easily keep track of the actual generating handler in a long line of delegations of handlers which avoids ClassCastExceptions at runtime as long as ComponentResettables implemented correctly

Throws:

FieldHandlingException - wraps all exceptions occuring during read or write access to fields

reset

public void reset(DoublePanel component)

Specified by:

reset in interface ComponentHandler<DoublePanel>
