validateParameters

public <T> Set<ConstraintViolation<T>> validateParameters(Class<T> clazz,
                                                          Method method,
                                                          Object[] parameters,
                                                          Class<?>... groupArray)

Validate each parameter value based on the constraints described on the parameters of method. enhancement: method-level-validation not yet completly implemented

 example:
 
 public @NotNull String saveItem(@Valid @NotNull Item item, @Max(23) BigDecimal
 
 

spec: The constraints declarations evaluated are the constraints hosted on the parameters of the method or constructor. If @Valid is placed on a parameter, constraints declared on the object itself are considered.

Specified by:

validateParameters in interface MethodValidator

Parameters:

clazz - class hosting the method

method - the method whose parameters are currectly validated

parameters - the parameter values passed to the method for invocation

groupArray - groups targeted for validation

Returns:

set of constraint violations

Throws:

IllegalArgumentException - enhancement: if the method does not belong to T or if the Object[] does not match the method signature

validateParameter

public <T> Set<ConstraintViolation<T>> validateParameter(Class<T> clazz,
                                                         Method method,
                                                         Object parameter,
                                                         int parameterIndex,
                                                         Class<?>... groupArray)

Validate the parameter value based on the constraints described on the parameterIndex-th parameter of method.

Specified by:

validateParameter in interface MethodValidator

Parameters:

clazz - class hosting the method

method - the method whose parameters are currectly validated

parameter - the parameter value passed to the parameterIndex-t parameter of method

parameterIndex - parameter index of the parameter validated in method

groupArray - groups targeted for validation

Returns:

set of constraint violations

validateParameters

public <T> Set<ConstraintViolation<T>> validateParameters(Class<T> clazz,

                                                         int parameterIndex,
                                                         Class<?>... groupArray)

Validate the parameter value based on the constraints described on the parameterIndex-th parameter of constructor.

Specified by:

validateParameter in interface MethodValidator

Parameters:

clazz - class hosting the constructor

constructor - the method whose parameters are correctly validated

parameter - the parameter value passed to the parameterIndex-th parameter of constructor

parameterIndex - parameter index of the parameter validated in constructor

groupArray - groups targeted for validation

Returns:

set of constraint violations

validateReturnedValue

public <T> Set<ConstraintViolation<T>> validateReturnedValue(Class<T> clazz,
