Class LambdaExpr

java.lang.Object

com.github.javaparser.ast.Node

com.github.javaparser.ast.expr.Expression

com.github.javaparser.ast.expr.LambdaExpr

All Implemented Interfaces:

NodeWithParameters<LambdaExpr>, Observable, Visitable, HasParentNode<Node>, Cloneable

public class LambdaExpr
extends Expression
implements NodeWithParameters<LambdaExpr>

A lambda expression. The parameters are on the left side of the ->. If a parameter uses type inference (it has no type specified) then its type is set to UnknownType. If they are in ( ), "isEnclosingParameters" is true. The body is to the right of the ->.
(a, b) -> a+b
a -> ...
(Long a) -> {println(a);}
