Class ProcessInfo.ProcessInfoSnapshot

java.lang.Object

org.rhq.core.system.ProcessInfo.ProcessInfoSnapshot

Enclosing class:

ProcessInfo

public final class ProcessInfo.ProcessInfoSnapshot
extends Object

Exposes non static process properties and operations computed on them (like isRunning() method). Operations on non static process properties should all be implemented here.

New snapshots are created when ProcessInfo.refresh() or ProcessInfo.freshSnapshot() are called.

Note the current implementation does not actually encapsulate these properties for backward compatibility reasons (we have to keep the write access to ProcessInfo protected properties).
