Method Detail

addConstraint

public <T> void addConstraint(java.lang.Class<? extends T> clazz,
                              ILocalConstraint<T> constraint)

Adds a constraint for a class.

checkConstaints

public void checkConstaints(java.lang.Object o)
                     throws ConstraintViolationException

Checks all constraints to the given object which are applicable to it.

Throws:

ConstraintViolationException - if any constraint is violated

checkConstaints

public <X extends java.lang.Exception> void checkConstaints(java.lang.Object o,
                                                            IExceptionHandler<ConstraintViolationException,X> handler)
                                                     throws X extends java.lang.Exception

Checks all constraints to the given object which are applicable to it. If a constraint is violated, the thrown exception is handled by the given provider.

Throws:

X extends java.lang.Exception

validateTree

public <T,X_WALKER extends java.lang.Exception> void validateTree(T root,
                                                                  ITreeWalker<T,X_WALKER> walker)

                                                                  X_WALKER extends java.lang.Exception

Validates all nodes of a tree. The first violation found is propagated to the top using a ConstraintViolationException.

Parameters:

root - the root of the tree.

walker - the walker used to navigate the tree.

Throws:

ConstraintViolationException - if a constraint violation was found.

X_WALKER - if the walker throws an exception.

X_WALKER extends java.lang.Exception

validateTree

public <T,X extends java.lang.Exception,X_WALKER extends java.lang.Exception> void validateTree(T root,
                                                                                                ITreeWalker<T,X_WALKER> walker,

                                                                                         throws X extends java.lang.Exception,
                                                                                                X_WALKER extends java.lang.Exception

Validates all nodes of a tree.

Parameters:
