Memory allocation for long-lived objects

A non-transitory computer-readable medium that stores a computer program for managing memory allocations in a computer system, the computer program including instructions that, when executed by at least one computer, cause the at least one computer to perform operations comprising:

• tagging a class of data structures with a tag that identifies a longer memory-allocation time for objects that correspond to the class, the tag being represented by a programming structure for the tag in a class definition file for the class;
• receiving a memory-allocation request for an object in a runtime operation for managing memory allocations, wherein the object corresponds to the class;
• accessing the class definition file in the runtime operation, the tag being associated with the class in the runtime operation through the programming structure for the tag;
• determining whether or not the object is associated with the tag through the class;
• if the object is not associated with the tag, allocating memory for the object from a first memory-allocation area that corresponds to a shorter memory-allocation time;
• and
• if the object is associated with the tag, allocating memory for the object from a second memory-allocation area that corresponds to the longer memory-allocation time.

An apparatus to manage memory allocations in a computer system, the apparatus comprising at least one computer configured to perform operations for computer-executable modules including:

• a class-tagging module that tags a class of data structures with a tag that identifies a longer memory-allocation time for objects that correspond to the class, the tag being represented by a programming structure for the tag in a class definition file for the class;
• an object-tagging module that:
• receives a memory-allocation request for an object in a runtime operation for managing memory allocations, wherein the object corresponds to the class;
• determines whether or not the object is associated with the tag through the class, the class definition file being accessed in the runtime operation, and the tag being associated with the class in the runtime operation through the programming structure for the tag;
• and
• a memory-allocation module that performs operations including:
• if the object is not associated with the tag, allocating memory for the object from a first memory-allocation area that corresponds to a shorter memory-allocation time;
• and
• if the object is associated with the tag, allocating memory for the object from a second memory-allocation area that corresponds to the longer memory-allocation time.
