Class HystrixObservableCommandChain<T>

java.lang.Object

com.netflix.ribbon.hystrix.HystrixObservableCommandChain<T>

public class HystrixObservableCommandChain<T>
extends java.lang.Object

This class implements chaining mechanism for Hystrix commands. If a command in a chain fails, the next one is run. If all commands in the chain failed, the error from the last one is reported. To be able to identify the Hystrix command for which request was executed, an ResultCommandPair event stream is returned by toResultCommandPairObservable() method. If information about Hystrix command is not important, toObservable() method shall be used, which is more efficient.
