All Implemented Interfaces:

public class FutureWriter
extends Writer

A Writer that will wrap around the user-provided writer if the user also provided an ExecutorService to the main PebbleEngine. A FutureWriter is capable of handling Futures that will return a string. It is not thread safe but that is okay. Each thread will have its own writer, provided by the "parallel" node; i.e. they will never share writers.
