System for modifying object oriented code

One or more processor readable storage devices having processor readable code embodied on said processor readable storage devices, said processor readable code for programming one or more processors to perform a method comprising the steps of:

• reading a rule defining a change to object code, said object code defining an object oriented class;
• searching said object code for an allocation of a first object based on a first class;
• finding said allocation of said first object based on said first class;
• modifying said object code based on said rule, said step of modifying includes changing said allocation of said first object based on said first class to an allocation of at least one object based on a second class.

An apparatus capable of modifying Java code, comprising:

• one or more input devices;
• one or more output devices;
• one or more processors in communication with said one or more input devices and said one or more output devices;
• and
• one or more storage devices in communication with said one or more processors, said one or more storage devices store program code, said program code programs said one or more processors to perform the steps of:
• reading a rule defining a change to Java object code, said Java object code defining an object oriented class;
• searching said object code for an allocation of a first object based on a first class;
• finding said allocation of said first object based on said first class;
• modifying said Java object code based on said rule, said step of modifying includes changing said allocation of said first object based on said first class to an allocation of said first object based on a second class, said second class extends said first class.

A method implemented on one or more machines for modifying object oriented code, comprising the steps of:

• reading a rule defining a change to object code, said object code including a definition of an object oriented class, said rule is in a machine readable format;
• modifying said object code based on said rule, said step of modifying includes changing first code that allocates a first object of a first class to second code that invokes a method that allocates said first object of said first class;
• and
• storing said modified object code in machine readable format, said steps of reading modifying and storing are performed by said one or more machines.

An apparatus capable of modifying object oriented code, comprising:

• one or more input devices;
• one or more output devices;
• one or more processors in communication with said one or more input devices and said one or more output devices;
• and
• one or more storage devices in communication with said one or more processors, said one or more storage devices adapted to store program code, said program code programs said one or more processor to perform the steps of:
• reading a rule defining a change to Java object code, said Java object code defining an object oriented class, and
• modifying said Java object code based on said rule, said step of modifying includes changing first code that allocates a first object of a first class to second code that invokes a static method that allocates said first object of said first class.

An apparatus capable of modifying object oriented code, comprising:

• one or more input devices;
• one or more output devices;
• a processor in communication with said one or more input devices and said one or more output devices;
• and
• a storage device in communication with said processor, said storage device adapted to store program code, said program code programs said processor to perform the steps of:
• reading a rule defining a change to Java object code, said Java object code defining an object oriented class, and
• modifying said Java object code based on said rule, said step of modifying includes changing a reference to a first static field to a reference to a second static field.
