Abstract: A method of integrating an existing source code into a target source code, the method including mapping a plurality of candidate mappings between a change point of the existing source code and a plurality of change points of the target source code, selecting a candidate mapping of the plurality of candidate mappings, automatically updating the existing source code based on the candidate mapping having been selected, and transplanting the existing source code having been updated into the target source code.

Abstract: An embodiment of the invention provides a method of displaying a data flow, wherein a description of a data flow application to be displayed is received. The data flow application includes nodes and edges connecting the nodes, wherein the nodes represent operators and the edges represent data connections for data flowing between the operations. A reason that a user is to view the data flow and/or a user constraint on a complexity of the data flow application to be displayed is determined with a processor; and, the time required to render a display of the data flow application is estimated. A transformed representation of the data flow application is created with the processor. The transformed representation is created based upon the user reason, the user constraint, the estimated time of rendering, and/or a layout strategy. The transformed representation is displayed on a graphical user interface.
