visitMethodInvocation
public java.lang.Void visitMethodInvocation(com.sun.source.tree.MethodInvocationTree tree, AnnotatedTypeMirror type)
This exists for Math.min and Random.nextInt, which must be special-cased.- Math.min has unusual semantics that combines annotations for the UBC.
- The return type of Random.nextInt depends on the argument, but is not equal to it, so a polymorphic qualifier is insufficient.

Description copied from class:TreeAnnotator
When overriding this method, getAnnotatedType on the left and right operands should only be called when absolutely necessary. Otherwise, the checker will be very slow on heavily nested binary trees. (For example, a + b + c + d + e + f + g + h.)If a checker's performance is still too slow, the types of binary trees could be computed in a subclass of
CFTransfer
. When computing the types in a transfer, look up the value in the store rather than the AnnotatedTypeFactory. Then this method should annotate binary trees with top so that the type applied in the transfer is always a subtype of the type the AnnotatedTypeFactory computes.- Specified by:
