Class CalledMethodsChecker

All Implemented Interfaces:
Processor, OptionConfiguration
Direct Known Subclasses:

@SuppressWarningsPrefix({"calledmethods","builder","","objectconstruction"}) @SupportedOptions({"useValueChecker","countFrameworkBuildCalls","disableBuilderFrameworkSupports","disableReturnsReceiver"}) @StubFiles({"DescribeImages.astub","GenerateDataKey.astub"}) public class CalledMethodsChecker extends AccumulationChecker
The Called Methods Checker tracks the methods that have definitely been called on an object. One common use case for the Called Methods Checker is to specify safe combinations of options to builder or builder-like interfaces, preventing objects from being instantiated incompletely.
  • Field Details


      public static final String COUNT_FRAMEWORK_BUILD_CALLS
      If this option is supplied, count the number of analyzed calls to build() in supported builder frameworks and print it when analysis is complete. Useful for collecting metrics.
      See Also:

      public static final String DISABLE_BUILDER_FRAMEWORK_SUPPORTS
      This option disables the support for (and therefore the automated checking of) code that uses the given builder frameworks. Useful when a user **only** wants to enforce specifications on custom builder objects (such as the AWS SDK examples).
      See Also:

      public static final String USE_VALUE_CHECKER
      If this option is supplied, use the Value Checker to reduce false positives when analyzing calls to the AWS SDK.
      See Also:

      public static final String DISABLE_RETURNS_RECEIVER
      Some use cases for the Called Methods Checker do not involve checking fluent APIs, and in those cases disabling the Returns Receiver Checker using this flag will make the Called Methods Checker run much faster.

    • getImmediateSubcheckerClasses

      protected Set<Class<? extends BaseTypeChecker>> getImmediateSubcheckerClasses()
      Description copied from class: BaseTypeChecker
      Returns the set of subchecker classes on which this checker depends. Returns an empty set if this checker does not depend on any others.

      Subclasses should override this method to specify subcheckers. If they do so, they should call the super implementation of this method and add dependencies to the returned set so that checkers required for reflection resolution are included if reflection resolution is requested.

      Each subchecker of this checker may also depend on other checkers. If this checker and one of its subcheckers both depend on a third checker, that checker will only be instantiated once.

      Though each checker is run on a whole compilation unit before the next checker is run, error and warning messages are collected and sorted based on the location in the source file before being printed. (See BaseTypeChecker.printOrStoreMessage(Diagnostic.Kind, String, Tree, CompilationUnitTree).)

      WARNING: Circular dependencies are not supported nor do checkers verify that their dependencies are not circular. Make sure no circular dependencies are created when overriding this method. (In other words, if checker A depends on checker B, checker B cannot depend on checker A.)

      This method is protected so it can be overridden, but it should only be called internally by the BaseTypeChecker.

      The BaseTypeChecker will not modify the list returned by this method, but other clients do modify the list.

    • isEnabled

      public boolean isEnabled(AccumulationChecker.AliasAnalysis aliasAnalysis)
      Check whether the given alias analysis is enabled by this particular accumulation checker.

      aliasAnalysis - the analysis to check
      true iff the analysis is enabled
    • typeProcessingOver

      public void typeProcessingOver()
      Description copied from class: AbstractTypeProcessor
      A method to be called once all the classes are processed.

      Subclasses may override this method to do any aggregate analysis (e.g. generate report, persistence) or resource deallocation.

      Method AbstractTypeProcessor.getCompilerLog() can be used to access the number of compiler errors.
