A method and apparatus for dependency processing of computer files. An embodiment of a method for dependency processing of computer files includes receiving a data stream input at a scanner component, where the data stream input represents multiple computer files. The data stream input is scanned for data types, where scanning the data stream input includes encountering a definition of a data type; determining whether to process program elements within the data type, and, if there is a determination to process the program elements in the data type, scanning the program elements of the data type to identify usages of the data type. The identified data type definition and data type usages are provided to a listening component.
