FutureWriter

java.lang.Object
- java.io.Writer
- - io.pebbletemplates.pebble.utils.FutureWriter

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable
```
public class FutureWriter
extends java.io.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.
