BaseTypeChecker
Each subclass of BaseTypeChecker must declare all dependencies it relies on if there are any. Each subchecker of this checker is in turn free to change its own dependencies. It's OK for various checkers to declare a dependency on the same subchecker, since the BaseTypeChecker will ensure that each subchecker is instantiated only once.
WARNING: Circular dependencies are not supported. We do not check for their absence. Make sure no circular dependencies are created when overriding this method.
This method is protected so it can be overridden, but it is only intended to be called internally by the BaseTypeChecker. Please override this method but do not call it from classes other than BaseTypeChecker. Subclasses that override this method should call super and added dependencies so that checkers required for reflection resolution are included if reflection resolution is requested.
The BaseTypeChecker will not modify the list returned by this method.

protected BaseTypeVisitor<?> createSourceVisitor()
BaseTypeChecker
This 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.
