Functional expression can be folded
Reports method references or lambda expressions that point to a method of their own functional interface type and hence can be replaced with their qualifiers removing unnecessary object allocation.
Example:
SwingUtilities.invokeLater(r::run);
SwingUtilities.invokeAndWait(() -> r.run());After the quick-fix is applied:
SwingUtilities.invokeLater(r);
SwingUtilities.invokeAndWait(r);- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
