Method Details

createFieldHandler

public abstract GeneralizedFieldHandler createFieldHandler(Class type)

Returns an array of the supported Class types for this FieldHandlerFactory. The array may be empty, but must not be null.
Returns:
an array of supported Class types.

isSupportedType

public abstract boolean isSupportedType(Class type)
Returns true if the given Class type is supported by this FieldHandlerFactory. If the type is supported, a call to #createFieldHandler will return a valid FieldHandler. If the type is not supported, a call to createFieldHandler may return null or throw a MappingException.
Parameters:
type - the Class type to determine support for.
Returns:
true if the given Class type is supported.
