Interface ThrowableUnaryOperator<T>

Type Parameters:
T - the type of the operand and result of the operator
All Superinterfaces:
Function<T,T>, UnaryOperator<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 ThrowableUnaryOperator<T> extends UnaryOperator<T>
Represents an operation on a single operand that produces a result of the same type as its operand. This is a specialization of Function for the case where the operand and result are of the same type.

Permits checked exceptions unlike UnaryOperator

This is a functional interface whose functional method is apply(Object).

    • applyUnsafe

      T applyUnsafe(T t) throws Throwable
      Applies this function to the given argument.
      Parameters:
      t - the function argument
      Returns:
      the function result
      Throws:
      Throwable - occurred during processing

    • apply

      default T apply(T t)
      Applies this function to the given argument.

      Has default implementation in order to make Function.compose(Function) and Function.andThen(Function) work.

      Specified by:
      apply in interface Function<T,T>
      Parameters:
      t - the function argument
      Returns:
      the function result

    • identity

      static <T> ThrowableUnaryOperator<T> identity()
      Returns a unary operator that always returns its input argument.
      Type Parameters:
      T - the type of the input and output of the operator
      Returns:
      a unary operator that always returns its input argument
