Method Detail

areEquivalent

public static boolean areEquivalent(@Nullable
                                    Tree leftNode,
                                    @Nullable
                                    Tree rightNode)

Returns:

true, if nodes are syntactically equivalent

areEquivalent

public static boolean areEquivalent(List<? extends Tree> leftList,
                                    List<? extends Tree> rightList)

Returns:

true, if nodes are syntactically equivalent

areEquivalent

public static boolean areEquivalent(List<? extends Tree> leftList,
                                    List<? extends Tree> rightList,
                                    BiPredicate<JavaTree,JavaTree> permissiveEquivalence)

Returns:

true, if nodes are syntactically equivalent Use permissiveEquivalence to force the equivalence of two nodes

areSemanticallyEquivalent

public static boolean areSemanticallyEquivalent(List<? extends Tree> leftList,
                                                List<? extends Tree> rightList)

Syntactic equivalence with additional semantic equivalence for methods calls. Two methods calls are equivalent only if they have the same signature; if the types of the arguments are the same.

Returns:

true, if nodes are syntactically and semantically equivalent.
