/**
 * Provides a utility for purging files and/or revision history for the DI server.
 *
 * <p>
 * <b>Example Request:</b><br>
 * POST /pur-repository-plugin/api/purge/path:to:file/purge
 * </p>
 *
 * @param pathId
 *          Colon separated path for the repository file. Processing of files will occur under this path. Exception:
 *          If purgeSharedObject=true other files may be affected as well.
 * @param purgeFiles
 *          If true, files will be purged completely. This options erases files and all history. This effectively
 *          disables all parameters effecting revisions since all revisions will be deleted unconditionally.
 * @param purgeRevisions
 *          If true, all revisions to the targeted files will be purged. The current state of the file will be
 *          retained.
 * @param purgeSharedObjects
 *          If true, Shared objects will also be targeted by the purge operation. This does not replace the pathId and
 *          fileFilter processing, but rather, is in addition to that processing. If it is desired to purge shared
 *          objects only without effecting other files, then set the pathId to a single space character. Some examples
 *          of shared objects database connections, Slave Servers, Cluster Schemas, and partition Schemas.
 * @param versionCount
 *          If present, the number of historical revisions to keep. If there are more revisions for a file than
 *          versionCount, the older ones will be removed.
 * @param purgeBeforeDate
 *          If set, remove all version history created prior to this date.
 * @param fileFilter
 *          The file filter to be applied when determining what files are affected by the purge. This filter is used
 *          by the <code>tree</code> endpoint to determine what files to return. The fileFilter is a list of allowed
 *          names of files separated by the pipe (|) character. Each file name in the filter may be a full name or a
 *          partial name with one or more wildcard characters ("*"). (eg: *.ktr|*.kjb returns all files with a ktr or
 *          kjb extension).
 * @param logLevelName
 *          The standard name for the log level (ie: INFO, DEBUG)
 * @return A text file containing a log of the service execution.
