distinct

public static <T> java.util.function.Function<reactor.core.publisher.Flux<T>,reactor.core.publisher.Flux<T>> distinct(java.util.function.Function<T,?> keySelector,
                                                                                                                      java.time.Duration duration)

构造有效期内去重的Flux

    flux.as(ReactorUtils.distinct(MyData::getId,Duration.ofSeconds(30)))
 

类型参数:

T - 泛型

参数:

keySelector - 去重的key

duration - 有效期

返回:

去重构造器

safeMap

public static <S,T> java.util.function.Function<reactor.core.publisher.Flux<S>,reactor.core.publisher.Flux<T>> safeMap(java.util.function.Function<S,T> mapper)

安全的转换Flux中的值,当mapper返回null时会忽略而不是报错

    flux
    .as(FluxUtils.safeMap(this::doConvert))
    ...

 

类型参数:

S - 源类型

T - 目标类型

参数:

mapper - 转换器

返回:

转换后的流
