Class DirectoryTrigger

java.lang.Object

com.arpnetworking.configuration.triggers.DirectoryTrigger

All Implemented Interfaces:

Trigger

public final class DirectoryTrigger
extends Object
implements Trigger

${link Trigger} implementation based on the contents of a directory. Configurable to either monitor all content or only specific content. The ${link FileTrigger} is used to determine whether a file changed. This is intended to monitor the files in a single directory and is not designed to monitor a directory tree (e.g. it is not recursive). Note: If you are monitoring a directory in which files are created and removed this implementation needs to be modified to purge file trigger instances when a file is removed!
