java.lang.Object

org.csstudio.opibuilder.widgetActions.CommandExecutor

public final class CommandExecutor
extends Object

Helper for executing a (system) command. On Unix, that could be anything in the PATH.

Several things can happen:

• Command finishes OK right away
• Command gives error right away
• Command runs for a long time, eventually giving error or OK.

The command executor waits a little time to see if the command finishes, and calls back in case of an error. When the command finishes right away OK or runs longer, we leave it be.
