Embodiment Construction

[0011] According to an example embodiment, in a distributed system there may be a large graph representing all source code of a certain source code repository or some source code repositories. Source code can be indexed to create graphs. In some embodiments, the graph may exist on one machine or several machines for remote access by developers, so that the graph is not run on each developer's machine, and the graph can be accessed simultaneously by multiple developers. In its simplest form, the graph can be two tables, the first mapping simple names to qualified names, and the second mapping qualified names to build system dependencies. By creating and accessing this graph in a distributed system or cloud environment, computations can be cached and reused among developers. In other embodiments, the graph may exist on the developer's own machine.

[0012] like figure 2 As shown, there are two simple names in the example source code file (201), "Bar" on line 3 and "Foo" on l...

Abstract

A system and method for finding candidates of qualified names for at least one simple name in a source code file are disclosed. A source code file may be received that has at least one simple name forwhich a corresponding qualified name is required. The source code file may be parsed to determine the simple names in the file and the qualified names in the file. For the at least one simple name for which a corresponding qualified name is required, a source code graph may be searched to find potential candidate qualified names that correspond to the at least one simple name. Upon receipt of a list of potential candidate qualified names from the source code graph, the list may be outputted to a user in order for the user to choose the appropriate qualified name. Build dependencies also be chosen for the qualified name.

Description

Background technique [0001] Developers often build complex software applications that include external code or libraries. For example, a developer may wish to include a list of people in their application. Instead of defining his own list objects, the developer may include list classes from external packages. in such as figure 1 In the example shown, a developer can include in his code a list from a standard library, such as "java.util.List". "java.util.List" is an ordered collection class publicly available through the java.util package. Once a list is imported into a developer's source code file, the developer can simply refer to the list by the simple name "List" instead of using the fully qualified name when instantiating or using the list everywhere" java.util.List". For example, in figure 1 In line 3 of , the code refers only to the simple name "List", not to the qualified name "java.util.List". [0002] While using a standard integrated development environment (I...
