com.atlassian.bitbucket.io.IoFunction<T, R>

Summary

Public Methods
<V> IoFunction<T, V> andThen(Function<? super R, ? extends V> after)
Returns a composed function that first applies this function to its input, and then applies the after function to the result.
R apply(T t)
Applies this function to the given argument.
<V> IoFunction<V, R> compose(Function<? super V, ? extends T> before)
Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static <T> IoFunction<T, T> identity()
Returns a function that always returns its input argument.

Public Methods

public IoFunction<T, V> andThen (Function<? super R, ? extends V> after)

Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Parameters
after the function to apply after this function is applied
Returns
  • a composed function that first applies this function and then applies the after function
Throws
NullPointerException if after is null

public R apply (T t)

Applies this function to the given argument.

Parameters
t the function argument
Returns
  • the function result
Throws
IOException

public IoFunction<V, R> compose (Function<? super V, ? extends T> before)

Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Parameters
before the function to apply before this function is applied
Returns
  • a composed function that first applies the before function and then applies this function
Throws
NullPointerException if before is null

public static IoFunction<T, T> identity ()

Returns a function that always returns its input argument.

Returns
  • a function that always returns its input argument
