LambdaHelper

LambdaHelper可以解析lambda

例如可以通过lambda获取其信息

LambdaExecutable lambdaExecutable = LambdaHelper.resolve((Serializable & BiConsumer<Integer[][], Integer>) (i, a) -> {});
System.out.println(lambdaExecutable);
// LambdaExecutable{
//  executable=private static void io.github.vampireachao.stream.core.lambda.LambdaHelperTest.lambda$testResolve$9b6dfab2$1(java.lang.Integer[][],java.lang.Integer),
//  instantiatedTypes=[class [[Ljava.lang.Integer;, class java.lang.Integer],
//  parameterTypes=[class [[Ljava.lang.Integer;, class java.lang.Integer],
//  returnType=void,
//  name='lambda$testResolve$9b6dfab2$1', 
//  clazz=class io.github.vampireachao.stream.core.lambda.LambdaHelperTest,
//  lambda=SerializedLambda[capturingClass=class io.github.vampireachao.stream.core.lambda.LambdaHelperTest, functionalInterfaceMethod=java/util/function/BiConsumer.accept:(Ljava/lang/Object;Ljava/lang/Object;)V, implementation=invokeStatic io/github/vampireachao/stream/core/lambda/LambdaHelperTest.lambda$testResolve$c70a867a$1:([[Ljava/lang/Integer;Ljava/lang/Integer;)V, instantiatedMethodType=([[Ljava/lang/Integer;Ljava/lang/Integer;)V, numCaptured=0],
//  proxy=null
// }

而且其在idea的debug模式下，在Evaluate调试窗口声明的lambda也可以被解析

拓展lambda

使用SerCons.multi，可以让你的forEach支持多个lambda操作

import static io.github.vampireachao.stream.core.lambda.function.SerCons.multi;


Arrays.asList("vampire", "a chao").forEach(multi(
        System.out::println,
        System.err::println,
        i -> System.out.println(i.equals("vampire"))
));
