Abstract: Methods, systems, and computer-readable storage media for receiving a key and a value of a data object, determining a first identifier and a second identifier based on the key, defining an entry object including the first identifier, the second identifier, and the value, and storing the entry object in a hashmap by: determining a first value of a first index based on the first identifier, determining a second value of a second index to provide a first value and second value pair that defines a first location within the hashmap storing the first identifier, determining a third value of a third index for the first value and second value pair, where the first value, the second value, and the third value define a second location within the hashmap storing the second identifier, and storing the value at a third location within the hashmap.

Abstract: Disclosed herein is a framework for analyzing and determining the impact and importance of software code or method changes. In accordance with one aspect, invocations of methods are tracked by generating marking records. The marking records may be used to rebuild a call stack, which can be used to organize the methods to generate a calling dependency representation. The methods may then be ranked based on such calling dependency representation.
