Interface Supplier<T>

  • All Superinterfaces:
    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.

    @GwtCompatible
    @FunctionalInterface
    public interface Supplier<T>
    extends Supplier<T>
    Legacy version of java.util.function.Supplier. Semantically, this could be a factory, generator, builder, closure, or something else entirely. No guarantees are implied by this interface.

    The Suppliers class provides common suppliers and related utilities.

    As this interface extends java.util.function.Supplier, an instance of this type can be used as a java.util.function.Supplier directly. To use a java.util.function.Supplier in a context where a com.google.common.base.Supplier is needed, use supplier::get.

    See the Guava User Guide article on the use of Function.
