Class CallGraph2JSON

  • public class CallGraph2JSON
extends java.lang.Object
    Utility class to serialize call graphs as JSON objects.

    The serialised objects have the form 

     {
   "<callsite1>": [ "<callee1>", "<callee2>", ... ],
   "<callsite2>": ...
 }
    where both call sites and callees are encoded as strings of the form 
     "<filename>@<lineno>:<beginoff>-<endoff>"
    Here, filename is the name of the containing JavaScript file (not including its directory), and lineno, beginoff and endoff encode the source position of the call expression (for call sites) or the function declaration/expression (for callees) inside the file in terms of its starting line, its starting offset (in characters from the beginning of the file), and its end offset.

        Extract the edges of the given callgraph as a map over strings that is easy to serialize. The map keys are locations of methods. The map values are themselves maps, from call site locations within a method to the (locations of) potential target methods for the call sites.
