FieldHandlerFriend

public FieldHandlerFriend()

Method Detail

getFieldDescriptor

protected abstract FieldDescriptor getFieldDescriptor()

Returns the FieldDescriptor for the field that this handler is responsible for, or null if no FieldDescriptor has been set. This method is useful for implementations of the FieldHandler interface that wish to obtain information about the field in order to make the FieldHandler more generic and reusable, or simply for validation purposes.

Returns:

the FieldDescriptor, or null if none exists.

setFieldDescriptor

public abstract void setFieldDescriptor(FieldDescriptor fieldDesc)

Sets the FieldDescriptor that this FieldHander is responsibile for. By setting the FieldDescriptor, it allows the implementation of the FieldHandler methods to obtain information about the field itself. This allows a particular implementation to become more generic and reusable.

Parameters:

fieldDesc - the FieldDescriptor to set

checkValidity

public abstract void checkValidity(Object object)
                            throws ValidityException,
                                   IllegalStateException

Deprecated. No longer supported

Specified by:

checkValidity in interface FieldHandler<T>

Throws:
