CFAbstractTransfersecondNode if the annotation secondValue is less
precise than firstvalue. This is possible, if secondNode is an expression
that is tracked by the store (e.g., a local variable or a field).
Note that when overriding this method, when a new type is inserted into the store, splitAssignments should be called, and the new type should be inserted into the store for each of the resulting nodes.
strengthenAnnotationOfEqualTo in class CFAbstractTransfer<CFValue,CFStore,CFTransfer>res - the previous resultnotEqualTo - if true, indicates that the logic is flipped (i.e., the information is
added to the elseStore instead of the thenStore) for a not-equal
comparison.null.protected void refineGT(Node left, AnnotationMirror leftAnno, Node right, AnnotationMirror rightAnno, CFStore store, TransferInput<CFValue,CFStore> in)
