The "API Usage Tool" (AUT) comprises an Interactive Developer Environment
Plug-in (IDEP) and a Web Service Component (WSC). The IDEP opens the
source code file containing API method calls, identifies the API method
calls in the source code, and saves the identified API method calls to an
API usage log. The WSC searches API usage data sheets for usage, best
practices and known bugs for each identified API method call. The WSC
generates an API usage compilation based on the identified API method
calls. The IDEP compares the API usage compilation to the dynamic data in
the usage log, looking for conflicts between the compiled usage and the
actual usage in the source code. The IDEP marks any API method calls in
the source code that do not comport with the compiled usage guidelines.
