Method Detail

addConstraint

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

Adds a constraint for a class.

checkConstaints

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

validateTree

public <T,X_WALKER extends Exception> void validateTree(T root,
                                                        ITreeWalker<T,X_WALKER> walker)
                  throws ConstraintViolationException,
                         X_WALKER extends 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 Exception

validateTree

public <T,X extends Exception,X_WALKER extends Exception> void validateTree(T root,
                                                                            ITreeWalker<T,X_WALKER> walker,
                                                                            IExceptionHandler<ConstraintViolationException,X> handler)
                  throws X extends Exception,
                         X_WALKER extends Exception

Validates all nodes of a tree.

Parameters:

root - the root of the tree.

walker - the walker used to navigate the tree.

handler - the exception handler used for dealing with constraint violations.

Throws:

X - if the constraint violation handler throws it.

X_WALKER - if the walker throws an exception.

X extends Exception

validateMesh

public <T,X_WALKER extends Exception> void validateMesh(T start,
                                                        IMeshWalker<T,X_WALKER> walker)
                  throws ConstraintViolationException,
                         X_WALKER extends Exception

Validates all reachable elements of a mesh. The first violation found is propagated to the top using a ConstraintViolationException.

Parameters:

start - the start element of the mesh.

walker - the walker used to navigate the mesh.

Throws:

ConstraintViolationException - if a constraint violation was found.

X_WALKER - if the walker throws an exception.

X_WALKER extends Exception

validateMesh

public <T,X extends Exception,X_WALKER extends Exception> void validateMesh(T start,
                                                                            IMeshWalker<T,X_WALKER> walker,
                                                                            IExceptionHandler<ConstraintViolationException,X> handler)
                  throws X extends Exception,
                         X_WALKER extends Exception

Validates all reachable elements of a mesh.

Parameters:

start - the start element of the mesh.

walker - the walker used to navigate the mesh.

handler - the exception handler used for dealing with constraint violations.

Throws:

X - if the constraint violation handler throws it.

X_WALKER - if the walker throws an exception.
