@Deprecated
public abstract class ParallelFlowable<T>
extends java.lang.Object
```
Abstract base class for Parallel publishers that take an array of Subscribers.
Use from() to start processing a regular Publisher in 'rails'. Use runOn() to introduce where each 'rail' shoud run on thread-vise. Use sequential() to merge the sources back into a single Flowable.

    Generates and flattens Publishers on each 'rail', optionally delaying errors.
    It uses unbounded concurrency along with default inner prefetch.
    
    Type Parameters:
    
    R - the result type
    
    Parameters:
    
    mapper - the function to map each rail's value into a Publisher
    
    delayError - should the errors from the main and the inner sources delayed till everybody terminates?
    
    Returns:
    
    the new ParallelFlowable instance

    Generates and flattens Publishers on each 'rail', optionally delaying errors and having a total number of simultaneous subscriptions to the inner Publishers.
    It uses a default inner prefetch.
    
    Type Parameters:
    
    R - the result type
    
    Parameters:
    
    mapper - the function to map each rail's value into a Publisher
    
    delayError - should the errors from the main and the inner sources delayed till everybody terminates?
    
    maxConcurrency - the maximum number of simultaneous subscriptions to the generated inner Publishers

    Generates and flattens Publishers on each 'rail', optionally delaying errors, having a total number of simultaneous subscriptions to the inner Publishers and using the given prefetch amount for the inner Publishers.
    
    Type Parameters:
    
    R - the result type
    
    Parameters:
    
    mapper - the function to map each rail's value into a Publisher
    
    delayError - should the errors from the main and the inner sources delayed till everybody terminates?
    
    maxConcurrency - the maximum number of simultaneous subscriptions to the generated inner Publishers
    
    prefetch - the number of items to prefetch from each inner Publisher
