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.

  • Leading and Trailing: Ignore the differences, if they appear in the end and in the beginning of a line.
  • All: white spaces are not important, regardless of their location in the source code.
Legend Shows summary information about the encountered differences: number of differences found, and color map.
