Duplicates tool window
The Duplicates tool window displays results of the search for duplicates.
Panes of the Duplicates tool window
The window consists of the following panes:
The left pane displays the tree view of the duplicate fragments of source code. Each node shows the following information:
The number of duplicated code fragments found in scope.
The 'cost' of the duplicate (which is an arbitrary unit calculated using an additive algorithm on the base of the code block size; generally, the larger is the code fragment, the higher is its cost).
The containing class where the duplicates are located.
The right pane shows the differences between the duplicated fragments of source code, selected in the left pane.
