public final class MethodReferenceExpr extends Expression implements NodeWithTypeArguments<MethodReferenceExpr>, NodeWithIdentifier<MethodReferenceExpr>
Method reference expressions introduced in Java 8 specifically designed to simplify lambda Expressions. Note that the field "identifier", indicating the word to the right of the ::, is not always a method name, it can be "new".
InSystem.out::println;
the scope is System.out and the identifier is "println"(test ? stream.map(String::trim) : stream)::toArray;
InBar<String>::<Integer>new
the String type argument is on the scope, and the Integer type argument is on this MethodReferenceExpr.- Author:
