View source

Summary: Groups the right data source and joins the resulting group to the left data source, matching these using the specified key selector. Results are included when the left and right have matching values. This is the equivalent of SQL inner join.

Type parameters

Name	Description
`TLeft`	The object type of the left data source.
`TLeftKey`	The key type of the left data source.
`TRight`	The object type of the right data source.
`TRightKey`	The key type of the right data source.
`TDestination`	The resulting object which.

Parameters

Name	Type	Description
`left`	IObservable>	The left data source.
`right`	IObservable>	The right data source.
`rightKeySelector`	Func	Specify the foreign key on the right data source.
`resultSelector`	Func, TDestination>	The result selector.used to transform the combined data into. Example (left, right) => new CustomObject(key, left, right).

Returns: IObservable> -- An observable which will emit change sets.
