Combiners allow to combine the result of multiple observable subscribers. There are some default implementations: see ObservableCombinerRunAllComponent, ObservableCombinerRunAllBoolOrComponent.

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