public interface BlockingStream<U>

Method Summary

Modifier and Type	Method and Description
default ListX<U>	block() React and block
default <R,A> R	block(java.util.stream.Collector<? super U,A,R> collector)
java.util.Optional<java.util.function.Consumer<java.lang.Throwable>>	getErrorHandler()
java.lang.Object	getLastActive()

Method Detail

getErrorHandler

java.util.Optional<java.util.function.Consumer<java.lang.Throwable>> getErrorHandler()

block

default ListX<U> block()

React and block

  
    	List<String> strings = new SimpleReact().<Integer, Integer> react(() -> 1, () -> 2, () -> 3)
    			.transform((it) -> it * 100)
    			.transform((it) -> "*" + it)
    			.block();
    	
                        
      

In this example, once the current thread of execution meets the React block method, it will block until all tasks have been completed. The result will be returned as a List. The Reactive tasks triggered by the Suppliers are non-blocking, and are not impacted by the block method until they are complete. Block, only blocks the current thread.

Returns:

Results of currently active stage aggregated in a List throws InterruptedException,ExecutionException

getLastActive

java.lang.Object getLastActive()

block

default <R,A> R block(java.util.stream.Collector<? super U,A,R> collector)

Parameters:

collector - to perform aggregation / reduction operation on the results (e.g. to Collect into a List or String)

Returns:

Results of currently active stage in aggregated in form determined by collector throws InterruptedException,ExecutionException
