protected LinkedHashSet<Class<? extends BaseTypeChecker>> getImmediateSubcheckerClasses()
BaseTypeCheckerSubclasses 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.
getImmediateSubcheckerClasses in class CalledMethodsCheckerprotected BaseTypeVisitor<?> createSourceVisitor()
BaseTypeCheckerThis implementation uses the checker naming convention to create the appropriate visitor. If
no visitor is found, it returns an instance of BaseTypeVisitor. It reflectively invokes
the constructor that accepts this checker and the compilation unit tree (in that order) as
arguments.
Subclasses have to override this method to create the appropriate visitor if they do not follow the checker naming convention.

AbstractTypeProcessorSubclasses 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.
