Object oriented program memory management system and method using fixed sized memory pools

A system for managing memory in an object oriented program operating on a computer, comprising:

• a memory pool class;
• a plurality of fixed pool subclasses of said memory pool class, said object oriented program being capable of using and instantiating objects belonging to said plurality of fixed pool subclasses;
• a plurality of memory pools each of a predetermined fixed size constructed during initialization of the object oriented program, each of said plurality of fixed pool subclasses having one of said plurality of memory pools associated therewith, wherein a size of each memory pool is determined from the maximum number of and size of objects that may be concurrently allocated for each associated fixed pool subclass during operation of the object oriented program;
• wherein memory for said objects of each of said fixed pool subclasses instantiated by said object oriented program are allocated from said associated memory pool.

A method for managing memory in an object oriented program, said object oriented program being capable of using a plurality of fixed pool classes and a plurality of objects belonging to said fixed pool classes, comprising the steps of:

• constructing a plurality of memory pools, each of said memory pools having a predetermined fixed size, and each of said plurality of fixed pool classes being associated with one of said plurality of memory pools, wherein a size of each memory pool is determined from the maximum number of and size of objects that may be allocated for each associated fixed pool class;
• constructing a plurality of object shells within a memory pool associated with a selected fixed pool class, each of said object shells being capable of becoming a defined object of said selected fixed pool class by receiving attribute data, said attribute data being stored in a database, wherein each object shell has not been assigned data values to define a state of an object;
• and
• instantiating a new object belonging to said selected fixed pool class by retrieving said attribute data from said database and inserting said attribute data into one of said object shells of said associated memory pool.
