Object Call Graph Visualization

In this dissertation a technique for visualizing internal behaviour of object oriented software program is created. The runtime information, that may be referred to as objects calling other objects, is shown as a graph comprising nodes and edges. The goal is to design an application in Java, that takes the runtime information in way of an object call graph and visualizes it as a tree and as a force directed view. Thus, first a data model should be designed, holding an object call sequence. In addition, a talk about graph definition languages and according tools is created. Following this different graph layout algorithms are analyzed in addition to graph displaying tools. Ultimately, the implementation of this visualization program deals with the combination of these 3 components graph data extraction, graph layout calculation and graph visualization…
