Call Graph

The "Call Graph" is a representational container which gives an over view of a Java project's structure in terms of files, classes and methods. Methods reside inside of classes and classes reside inside of files.

The Call Graph goes through two phases of initialization before it can be used. The first stage is know as the Parsing Stage and the second is known as the Resolving Stage.

Once the Call Graph has been initialized, a number of analytical queries can be put against it to draw out wanted data. For example a user can give the call graph a method and find out all information about said method; information such as return type, parameter types, methods that it calls, methods it is called by, the class it is in, the file it is in and so on.

The Call Graph itself is just an information bucket.

Call Graph Contains

• A hash map of Files.
• A hash map of Clazzes.
• A hash map of Methods.
