Package com.inductiveautomation.ignition.common.sqltags.scripts

Class TagScriptManager.TagScriptDispatcher

java.lang.Object

com.inductiveautomation.ignition.common.sqltags.scripts.TagScriptManager.TagScriptDispatcher

All Implemented Interfaces:

TagScriptEvaluator, Runnable

Enclosing class:

TagScriptManager

protected class TagScriptManager.TagScriptDispatcher
extends Object
implements Runnable, TagScriptEvaluator

This is the actual returned evaluator. The basic goal is that we want to execute tasks asynchronously, without allowing them to back up. So we create one of these per tag, and it manages tracking the number of outstanding events.
