org.formulacompiler.compiler
Interface SaveableEngine

All Superinterfaces:
Engine
public interface SaveableEngine
extends Engine

Defines the saveTo(OutputStream) method for engines returned by an engine compiler. This allows you to save a compiled engine to persistent storage and then later re-instatiate it using FormulaRuntime.loadEngine(java.io.InputStream).

The Engine interface does not have save support so as not to burden the run-time-only support with it.

This interface is an API only. Do not implement it yourself.
