Analysis of object flow during execution of individual instructions of a method within an object-oriented application provides information regarding the creation and flow of objects during an invocation of the method. This analysis information is used to track where objects enter an invocation of the method and track their path during the execution of the method. The operand stack, register, and local variables references to the objects are tracked as each instruction in the method is executed. Where objects are passed to elements outside of the method invocation is tracked as well. This tracking of object flow uses an iterative data-flow analysis. If an object is passed to the method or created within the method, the embodiments described herein may be used to determine where that object can go from that point onwards, whether to other method invocations, arrays, or data fields within the application.
