Reference for Eclipse as-you-type compiler (or feature) [message #1403981]

Hi,

In Eclipse, under Java > Editor, there is a feature:
"Report problems as you type"

I am looking for a web reference on how Eclipse internally provides continuous feedback on edits, especially the ones that are not saved to the disk yet.

I know that Eclipse JDT Core component comes with an incremental java compiler build as an Eclipse project builder. However, to my best knowledge, project builders work on the difference between two executions of the incremental java compiler, which runs on the file system, not on editor buffers.

Is there a better reference I can use when I mention about Eclipse's on-the-fly compilation and continuous feedback?

Thanks,

JDT's compiler comes in different guises Smile

When driven by the builder it's org.eclipse.jdt.internal.compiler.Compiler, which indeed works on files on disk

When working on unsaved buffer content, it's org.eclipse.jdt.internal.core.CompilationUnitProblemFinder (which extends the above).
This operation is also called "reconciling".

Hi Stephan,

Thank you very much for the pointers. I wanted reference the fact that Eclipse extends its file-system based compiler to provide on-the-fly information about warnings and errors on unsaved buffer content in academic context. On main page of JDT Core, the incremental file-system compiler is featured, but there is no information about this extension. Some Internet search did not reveal any documents either.

In your opinion, what would be the best link/document as a citation?

Thanks,
