Interface Output

All Known Implementing Classes:

AppendTo, CheckedOutput, CloseShieldOutput, DeadOutput, GzipOutput, LoggingOutput, OutputNoNulls, OutputTo, Stderr, Stdout, SyncOutput, TeeOutput, UncheckedOutput

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 Output

Output.

Here is for example how Output can be used together with Input in order to modify the content of a text file:

 new LengthOf(
   new TeeInput(
     new InputOf(new TextOf("Hello, world!")),
     new OutputTo(new File("/tmp/names.txt"))
   )
 ).asValue();

Here OutputTo implements Output and behaves like one, providing write-only access to the encapsulated File. The TeeInput copies the content of the input to the output. The LengthOf calculates the size of the copied data.

There is no thread-safety guarantee.
