Method Detail

visitBinary

public Void visitBinary(BinaryTree node,
                        AnnotatedTypeMirror type)

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.
