Record Class Throwing<T>

java.lang.Object
java.lang.Record
com.winterhavenmc.library.messagebuilder.validation.Throwing<T>
Type Parameters:
T - the type of the value being validated
All Implemented Interfaces:
Validator<T>
public record Throwing<T>(Supplier<ValidationException> exceptionSupplier) extends Record implements Validator<T>
A Validator implementation that throws a ValidationException when a value fails validation.

The exception is supplied via a Supplier, allowing lazy instantiation and support for dynamic message construction.

The exception's stack trace is reset via Throwable.fillInStackTrace() to ensure that the reported call site accurately reflects the point of failure, rather than the supplier's origin.

Typical usage:

 validate(value, Predicate, Validator.throwing(ErrorMessageKey, Parameter));
