Method Detail

getArgument

RequestArgumentType getArgument()

The request argument passed into the HystrixCollapser instance constructor which was then collapsed.

Returns:

RequestArgumentType

setResponse

void setResponse(ResponseType response)

This corresponds in a OnNext(Response); OnCompleted pair of emissions. It represents a single-value usecase.

Parameters:

response - ResponseType

Throws:

java.lang.IllegalStateException - if called more than once or after setException/setComplete.

emitResponse

void emitResponse(ResponseType response)

When invoked, any Observer will be OnNexted this value

Parameters:

response -

Throws:

java.lang.IllegalStateException - if called after setException/setResponse/setComplete.

setException

void setException(java.lang.Exception exception)

When set, any Observer will be OnErrored this exception

Parameters:

exception - exception to set on response

Throws:

java.lang.IllegalStateException - if called more than once or after setResponse/setComplete.

setComplete

void setComplete()

When set, any Observer will have an OnCompleted emitted. The intent is to use if after a series of emitResponses Note that, unlike the other 3 methods above, this method does not throw an IllegalStateException. This allows Hystrix-core to unilaterally call it without knowing the internal state.
