Class MethodReferenceExpr

java.lang.Object

com.github.javaparser.ast.Node

com.github.javaparser.ast.expr.Expression

com.github.javaparser.ast.expr.MethodReferenceExpr

All Implemented Interfaces:

NodeWithTypeArguments<MethodReferenceExpr>, Cloneable

public class MethodReferenceExpr
extends Expression
implements NodeWithTypeArguments<MethodReferenceExpr>

Method reference expressions introduced in Java 8 specifically designed to simplify lambda Expressions. These are some examples: System.out::println; (test ? stream.map(String::trim) : stream)::toArray;
