Method Detail

displayableConstraint

public static java.util.List<F.Tuple<java.lang.String,java.util.List<java.lang.Object>>> displayableConstraint(java.util.Set<javax.validation.metadata.ConstraintDescriptor<?>> constraints)

Converts a set of constraints to human-readable values. Does not guarantee the order of the returned constraints.

displayableConstraint

public static java.util.List<F.Tuple<java.lang.String,java.util.List<java.lang.Object>>> displayableConstraint(java.util.Set<javax.validation.metadata.ConstraintDescriptor<?>> constraints,
                                                                                                               java.lang.annotation.Annotation[] orderedAnnotations)

Converts a set of constraints to human-readable values in guaranteed order. Only constraints that have an annotation that intersect with the orderedAnnotations parameter will be considered. The order of the returned constraints corresponds to the order of the orderedAnnotations parameter.

displayableConstraint

public static F.Tuple<java.lang.String,java.util.List<java.lang.Object>> displayableConstraint(javax.validation.metadata.ConstraintDescriptor<?> constraint)

Converts a constraint to a human-readable value.

required

public static Constraints.Validator<java.lang.Object> required()

Constructs a 'required' validator.

min

public static Constraints.Validator<java.lang.Number> min(long value)

Constructs a 'min' validator.

max

public static Constraints.Validator<java.lang.Number> max(long value)

Constructs a 'max' validator.

minLength

public static Constraints.Validator<java.lang.String> minLength(long value)

Constructs a 'minLength' validator.

maxLength

public static Constraints.Validator<java.lang.String> maxLength(long value)

Constructs a 'maxLength' validator.

email

public static Constraints.Validator<java.lang.String> email()

Constructs a 'email' validator.

pattern

public static Constraints.Validator<java.lang.String> pattern(java.lang.String regex)
