Class SnapshotReport

java.lang.Object

org.rhq.core.pluginapi.util.SnapshotReport

public class SnapshotReport
extends Object

A common snapshot report that allows you to prepare a zip'ed file containing a snapshot of content belonging to a resource. This report contains a snapshot configuration, log and data files along with a customizable set of additional files. Users of this object can pick and choose which types of files to snapshot and filter the files of those types. This class can be subclassed if you wish to alter the way it collects and stores the snapshot content. For example, if the configuration is not stored as files, but instead stored in memory, you can subclass this to obtain the configuration by reading memory, writing that data to a temporary file and then having this class add that temporary file to the snapshot zip file.
