Method, program and system for automatic reengineering of a client code

A method of automatic reengineering of an input client code using an API when an API adapter code is provided for emulating an old version of the API on a new version of the API, wherein items no longer provided in the new API are identified, said method comprising the steps of:

• generating a memory representation of an API adapter code;
• building an index of the items of the API adapter code memory representation of which new API items have been identified;
• generating a parametrized code memory representation of replacement code for the calls to the identified items;
• parsing the input client code into a memory representation of the input client code;
• searching to locate in the memory representation of the input client code for calls of which new API items have been identified and reading corresponding call parameters;
• replacing the located calls by the parametrized code memory representation of replacement code including the corresponding call parameters read while searching for the calls;
• and
• generating code corresponding to the memory representation of the input client code wherein the calls have been replaced.

A computer program product comprising programming code instructions for executing the steps of the method of automatic reengineering of an input client code using an API when an API adapter code is provided for emulating an old version of the API on a new version of the API, wherein items no longer provided in the new API are identified, when said program is executed on a computer, said computer program product comprising:

• computer program instructions for generating a memory representation of an API adapter code;
• computer program instructions for building an index of the items of the API adapter code memory representation of which new API items have been identified;
• computer program instructions for generating a parametrized code memory representation of replacement code for the calls to the identified items;
