Class VoidCompiler

java.lang.Object

bayou.reload.VoidCompiler

All Implemented Interfaces:

HotCompiler

public class VoidCompiler
extends Object
implements HotCompiler

A HotCompiler that generates no output.

The purpose of a VoidCompiler is to reload the application if some files are changed (but requiring no recompilation). For example, if the application reads ".properties" files on startup and cache the information in memory, it needs to be reloaded if some of the files are changed.

See also HotReloader.onFiles(fileDesc, filePattern, srcDirs).
