Class Validator

java.lang.Object

dev.relism.flash.ext.jackson.Validator

public final class Validator
extends Object

The compiled constraints of one type. Built once per class and reused for every request.

verify(java.lang.Object) allocates nothing when a value passes: the loop walks an array (no iterator), reads fields through exact-signature MethodHandles (no boxing, no argument array), and compares against operands resolved at compile time. The violation list and the exception are constructed only once something actually fails.

Method Summary

Modifier and Type	Method	Description
static <T> T	check(T value)	Verifies a value against its own type's constraints.
boolean	isEmpty()	True when the type declares no constraints at all — verify(java.lang.Object) is then a no-op.
static Validator	of(Class<?> type)	The constraints of type, compiled the first time it is seen and reused after.
void	verify(Object target)	Verifies every constraint on target.

Method Details

of

public static Validator of(Class<?> type)

The constraints of type, compiled the first time it is seen and reused after.

check

public static <T> T check(T value)

Verifies a value against its own type's constraints.

Returns:

value, so it can be used inline

Throws:

ValidationException - 422, listing every failure

isEmpty

public boolean isEmpty()

True when the type declares no constraints at all — verify(java.lang.Object) is then a no-op.

verify

public void verify(Object target)

Verifies every constraint on target.

Throws:

ValidationException - with all failures, never just the first
