Interface ThrowableSupplier<T,​E extends java.lang.Throwable>

  • Type Parameters:
    T - The type this supplier is supposed to return.
    E - The type of exception this Supplier is expected to throw.
    All Superinterfaces:
    java.util.function.Supplier<T>
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @FunctionalInterface
    public interface ThrowableSupplier<T,​E extends java.lang.Throwable>
    extends java.util.function.Supplier<T>
    Simple hack to add checked error support to a Suppliers. It is mainly used in conjunction with Utilities.supplierHandling(ThrowableSupplier, Consumer) to achieve error handling within a Supplier.
