Description copied from class: StripTrailingSpacesFilterFactory

Creates a filter which may restrict trailing spaces removal.

Specified by:

createFilter in class StripTrailingSpacesFilterFactory

Parameters:

project - The current project or null if there is no project context.

document - The document to be processed.

Returns:

The filter which will be called on document save. The factory may return one of the several predefined filters:

• StripTrailingSpacesFilter.NOT_ALLOWED No stripping allowed. The IDE will not try to strip any whitespace at all in this case.
• StripTrailingSpacesFilter.POSTPONED The stripping is not possible at the moment. For example, the caret is in the way and the "Settings|General|Editor|Allow caret after end of the line" is off. In this case, the IDE will try to restart the stripping later.
• StripTrailingSpacesFilter.ALL_LINES Allow stripping with no restrictions. Return this value by default.
