056/**
057 * This class defines an API that must be implemented by extensions that perform
058 * some processing immediately after an LDIF export task has completed.  Note
059 * that this is only an option for LDIF exports invoked as administrative
060 * tasks (including as part of a recurring task), and not for standalone
061 * exports not invoked by an administrative task.
062 * <BR>
063 * <H2>Configuring Post-LDIF-Export Task P rocessors</H2>
064 * In order to configure a post-LDIF-export task processor created using this
065 * API, use a command like:
066 * <PRE>
067 *      dsconfig create-post-ldif-export-task-processor \
068 *           --processor-name "<I>{processor-name}</I>" \
069 *           --type third-party \
070 *           --set enabled:true \
071 *           --set "extension-class:<I>{class-name}</I>" \
072 *           --set "extension-argument:<I>{name=value}</I>"
073 * </PRE>
074 * where "<I>{processor-name}</I>" is the name to use for the post-LDIF-export
075 * task processor instance, "<I>{class-name}</I>" is the fully-qualified name of
076 * the Java class that extends
077 * {@code com.unboundid.directory.sdk.ds.api.PostLDIFExportTaskProcessor}, and
078 * "<I>{name=value}</I>" represents name-value pairs for any arguments to
079 * provide to the processor.  If multiple arguments should be provided to
080 * the processor, then the
081 * "<CODE>--set extension-argument:<I>{name=value}</I></CODE>" option should be
082 * provided multiple times.
