initialize in interface ConstraintValidator<Size,Object[]>

Parameters:

parameters - annotation instance for a given constraint declaration

isValid

public boolean isValid(Object[] array,
                       ConstraintValidatorContext constraintValidatorContext)

Checks the number of entries in an array.

Specified by:

isValid in interface ConstraintValidator<Size,Object[]>

Parameters:

array - The array to validate.

constraintValidatorContext - context in which the constraint is evaluated.

Returns:
