Inspectopedia Help

Method can be extracted

Suggests extracting fragments of code to a separate method to make code more clear. This inspection has a number of heuristics to select good candidates for extraction, including the following ones.

  • The extracted fragment has no non-local control flow

  • The extracted fragment has exactly one output variable

  • There are no similar uses of output variable inside the extracted fragment and outside it

  • The extracted fragment has only few input parameters (no more than three by default; configured with the inspection option)

  • The extracted fragment is not smaller than the configured length (500 characters by default) but no bigger than 60% of the containing method body

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
