Method Detail

processFile

public java.lang.Runnable processFile(PsiFile file)

Description copied from interface: ImportOptimizer

Implementers of the method are expected to perform all necessary calculations synchronously and return a Runnable, which performs modifications based on preprocessing results. processFile() is guaranteed to run with Application.runReadAction(Runnable) privileges and the Runnable returned is guaranteed to run with Application.runWriteAction(Runnable) privileges. One can theoretically delay all the calculation until Runnable is called but this code will be executed in Swing thread thus lengthy calculations may block user interface for some significant time.

Specified by:

processFile in interface ImportOptimizer

Parameters:

file - to optimize an imports in. It's guaranteed to have a language this ImportOptimizer have been issued from.

Returns:

a java.lang.Runnable object, which being called will replace original file imports with optimized version.

supports

public boolean supports(PsiFile file)

Description copied from interface: ImportOptimizer

Call to this method is made before the processFile() call to ensure implementation can process the file given

Specified by:

supports in interface ImportOptimizer

Parameters:

file - file to check

Returns:

true if implementation can handle the file
