IntelliJ IDEA 13.1.0 Web Help

File | Settings | Project Settings | Language Injection - Advanced

settings

Use this tab to specify different names for the base-annotations to be used. This helps avoid any dependencies on foreign code where it is not desired or possible. The custom annotations should provide the same properties as the original ones, i.e. value for all of them and an optional (default = "") prefix and suffix for the @Language replacement.

Also configure the runtime checks to be generated for the @Pattern validation.

Item Description
Annotation Classes In this area, specify the classes that implement annotations of the following types:
  • Language annotations
  • Pattern annotations
  • Substitution annotations

Type the class names, possibly using code completion. If necessary, use the Browse button browseButton.png to open the Select Class dialog box, where you can you can locate the desired class in the project tree view. Alternatively, switch to the Search by Name tab and start typing the class name. As you type, the list of available classes narrows down to match your entry.

Runtime Pattern Validation In this area, configure the runtime checks to be generated for the @Pattern validation. The available options are:
  • No runtime instrumentation - if this option is selected, no checks will be inserted and any compiled class files will be affected.
  • Instrument with assertions - if this option is selected, pattern-validation is controlled with the -ea JVM switch and throws AssertionError.

    Tip

    Selecting this option is recommended due to the potentially negative impact on the performance for methods that are invoked very often.

  • Instrument with IllegalArgumentException - select this option to have the same result as when the @NotNull instrumentation of IntelliJ IDEA is used.
Performance Click one of the radio buttons in this area to select the level of analysis and performance of the language injections resolution procedure.
  • Do not analyze (fast) - if this option is selected, IntelliJ IDEA does not analyze injections.

    Tip

    Selecting the Do not analyze option significantly improves performance.

  • Analyze references - if this option is selected, IntelliJ IDEA attempts to recognize injections introduced through variables.
  • Look for variable assignments - if this option is selected, IntelliJ IDEA does not perform the dataflow analysis to detect the substitution strings, but looks for variable assignments only.
  • Use dataflow analysis (slow) - if this option box is selected, IntelliJ IDEA applies dataflow analysis to language injections.
Include undefined operands to text in concatenation If this check box is selected, IntelliJ IDEA inserts an injected operand as a literal, if its type is not recognized.
