NAME

OP::RRNode - Circular "Round Robin" Table Rows

DESCRIPTION

Abstract implementation of a circular FIFO object class.

The DB table for a FIFO subclass will never grow beyond the limit set by the subclass's __numRows variable. When the row limit is reached, the oldest rows in the database will begin to be overwritten.

Suitable applications for subclasses include event logging, message queueing, and RRD-style data collection.

INHERITANCE

This class inherits additional class and object methods from the following packages:

OP::Class > OP::Object > OP::Hash > OP::Node > OP::RRNode

SYNOPSIS
