Detailed Description

Offers a class that collects unified diff invocations to be able to iterate through the differences, show them on the stc component, or checkout a difference.

For each single diff the insert should be called, and after the last one finish should be called.

Member Function Documentation

◆ checkout()

bool wex::unified_diffs::checkout ( size_t line )

Checks out the difference on specified line.

It reverts the changes on that line, and removes key from the container, and resets the iterator to begin.

◆ next()

bool wex::unified_diffs::next ( )

Goto next diff line on stc.

If at end (we are not on the last of all differences), goes to the next stc. If on first position of stc, goes to first diff line.

◆ pos()

size_t wex::unified_diffs::pos ( ) const

Returns position of iterator in the collection.

The first element has number 1, 0 is returned if no differences are present.

◆ prev()

bool wex::unified_diffs::prev ( )

Goto previous diff line on stc.
