Interface Summary

Constraint

A function object that tests one argument and returns a single boolean result.

Class Summary

AbstractBinaryConstraint
AbstractConstraint
AbstractTypeResolvablePropertyConstraint
And	A "and" compound constraint (aka conjunction).
ClosureResultConstraint	Tests the result returned from evaluating a closure closure.
ComparisonBinaryPredicate	Abstract helper superclass for binary predicates involved in comparison operations.
CompoundConstraint	Abstract base class for unary constraints which compose other constraints.
ConstraintsAccessor	A convenience constraints factory accessor for easy subclassing.
EqualTo	Constraint that tests object equality (not identity.)
GreaterThan	Predicate that tests if one comparable object is greater than another.
GreaterThanEqualTo	Predicate that tests if one comparable object is greater than or equal to another.
IfTrue
InGroup	A constraint that tests if an argument is one of a group.
LessThan	Predicate that tests if one comparable object is less than another.
LessThanEqualTo	Predicate that tests if one comparable object is less than or equal to another.
Like	A like constraint, supporting "starts with%", "%ends with", and "%contains%".
Like.LikeType
LogicalOperator	Type-safe enums for various conditional or logical operators.
MethodInvokingConstraint	A adapter that can adapt a method on an object that accepts a single argument and returns a boolean result a UnaryPredicate.
Not	"Nots" another unary constraint (the inverse) by using composition.
Operator
Or	A "or" compound constraint (aka disjunction).
ParameterizedBinaryConstraint	A unary constraint adapting a binary constraint that uses a parameterized constant value as the second argument when testing.
Range	A range whose edges are defined by a minimum Comparable and a maximum Comparable.
RegexpConstraint	A constraint based on a regular expression pattern.
RelationalOperator	Type-safe enum class for supported binary operators.
Required	Validates a required property.
StringLengthConstraint	Constraint to validate an object's string length.
TypeResolvableConstraint	Convenient abstract super class for predicates whose type's are resolvable, useful for mapping the type to a i18n message in a message source.
WildcardConstraint	Always returns true; a wildcard match
XOr	A "xor" compound constraint (aka exclusive disjunction).
