Method Detail

initialize

public void initialize(Size parameters)

Description copied from interface: ConstraintValidator

Initializes the validator in preparation for ConstraintValidator.isValid(Object, ConstraintValidatorContext) calls. The constraint annotation for a given constraint declaration is passed.

This method is guaranteed to be called before any use of this instance for validation.

The default implementation is a no-op.

Specified by:

initialize in interface ConstraintValidator<Size,Map>

Parameters:

parameters - annotation instance for a given constraint declaration

isValid

public boolean isValid(Map map,
                       ConstraintValidatorContext constraintValidatorContext)

Checks the number of entries in a map.

Specified by:

isValid in interface ConstraintValidator<Size,Map>

Parameters:

map - The map to validate.

constraintValidatorContext - context in which the constraint is evaluated.

Returns:

Returns true if the map is null or the number of entries in map is between the specified min and max values (inclusive), false otherwise.
