transformCheckedWithExn

public final <Y extends Exception> T transformCheckedWithExn(E input,
                                                             Class<Y> exnClass)
                                throws Y extends Exception

Execute this transformer, making sure that an exception of type exnClass is thrown.

Type Parameters:

Y - type of exception to throw.

Parameters:

input - the input.

exnClass - class exception to throw.

Returns:

the result of this transformer.

Throws:

Y - if transformChecked(Object) throws an exception, it will be wrapped (if necessary) in an exception of class exnClass.

Y extends Exception

transformCheckedWithExn

public final <Y extends Exception,Z extends Exception,A extends Exception> T transformCheckedWithExn(E input,
                                                                                                     boolean wrapRT,

                                throws Y extends Exception,
                                       Z extends Exception,
                                       A extends Exception

Execute this transformer, wrapping exceptions thrown by transformChecked(Object) into one of the passed exception classes.

Type Parameters:

Y - type of exception to throw.

Z - second type of exception to throw.

A - third type of exception to throw.

Parameters:

input - the input.

wrapRT - true so that even RuntimeException are wrapped into Y, false if this method should throw them as they are.

exnClass - class exception to throw.

exnClass2 - class exception to throw, can be null.

exnClass3 - class exception to throw, can be null.

Returns:

the result of this transformer.

Throws:

Y - if transformChecked(Object) throws an exception, it will be wrapped (if necessary) in an exception of class exnClass.

Z - if transformChecked(Object) throws an exception of class Z.

A - if transformChecked(Object) throws an exception of class A.

Y extends Exception

transformChecked

public abstract T transformChecked(E input)
                            throws X extends Exception

Specified by:

transformChecked in interface ITransformerExn<E,T,X extends Exception>

Throws:
