Function0

All Superinterfaces:

java.io.Serializable, java.util.function.Supplier<R>

All Known Implementing Classes:

CheckedFunction0, Functions0.AtomicIntegerZeroFunction, Functions0.AtomicLongZeroFunction, Functions0.BigDecimalZeroFunction, Functions0.BigIntegerZeroFunction, Functions0.FalseFunction, Functions0.IntegerZeroFunction, Functions0.NewFastListFunction, Functions0.NewHashBagFunction, Functions0.NewUnifiedMapFunction, Functions0.NewUnifiedSetFunction, Functions0.NullFunction, Functions0.ThrowingFunction0Adapter, Functions0.TrueFunction, PassThruFunction0

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 Function0<R>
extends java.util.function.Supplier<R>, java.io.Serializable
```
Function0 is a zero argument lambda. It can be stored in a variable or passed as a parameter and executed by calling the value method.
