InitCombine()

MAXON_METHOD Result<void> InitCombine

(

Result< Data > &

combinedRes

)

const

Called first before the observable notification starts. In general the start result value will be copied to the result value.

Parameters

[out]

combinedRes

Receives the start value.

Returns

OK on success.

CombineResult()

MAXON_METHOD Result<Bool> CombineResult	(	Result< Data > &	combinedRes,
		Result< Data > &&	newRes
	)		const

Called after each notification. This function defines how the results are combined together. The return value controls if following subscribers should be called.

Parameters

[in,out]	combinedRes	Contains the last result and receives the new result.
[in]	newRes	The new result that needs to be combined with combinedRes.

Returns

True if the the next subscriber should be called. False if the notification should stop here.
