终端操作评估中间操作

Question

List<String> scripts;

//initialize list

ScriptRunnerBuilder scriptRunnerBuilder = new ScriptRunnerBuilder();

BiFunction<String,ScriptRunnerBuilder,ScriptRunnerBuilder> addScript = 
(script,builder) -> builer.addScript(script);

scriptRunnerBuilder = scripts.stream.map(script -> 
addScript.apply(script,scriptRunnerBuilder)).......

scriptRunnerBuilder.build();

Answer 1

最简单的方法应该是：

// create your builder
ScriptRunnerBuilder builder = new ScriptRunnerBuilder();

// add all scripts
scripts.forEach(script-> builder.addScript(script))

build results
scriptRunnerBuilder.build();

因为builder聚合了所有数据，并且您已经在forEach lambda之外创建了这些数据，所以您可以直接访问这些数据。这将导致更少的代码和相同的结果。

或者像@Holger建议的那样：

scripts.forEach(builder::addScript);
