Examples of com.google.dart.engine.source.Source

com.google.dart.engine.source.Source
The interface {@code Source} defines the behavior of objects representing source code that can beanalyzed by the analysis engine.
Implementations of this interface need to be aware of some assumptions made by the analysis engine concerning sources:
- Sources are not required to be unique. That is, there can be multiple instances representing the same source.
- Sources are long lived. That is, the engine is allowed to hold on to a source for an extended period of time and that source must continue to report accurate and up-to-date information.
Because of these assumptions, most implementations will not maintain any state but will delegate to an authoritative system of record in order to implement this API. For example, a source that represents files on disk would typically query the file system to determine the state of the file.
If the instances that implement this API are the system of record, then they will typically be unique. In that case, sources that are created that represent non-existent files must also be retained so that if those files are created at a later date the long-lived sources representing those files will know that they now exist. @coverage dart.engine.source
