Remarks

JoinWithin identifies those features in the source table that are contained by features in the table being joined.

For example, if the source layer containing line features (rivers) is spatially joined to a layer which contains polygon features (administrative boundaries), with the LeftOuterJoin property set to TRUE, the new output layer will contain a record for each feature in the source table with all the attribute columns from the join table appended. Where a JoinWithin match was identified, each river in the new feature class will now have additional attribute information about the administrative boundary it falls within. Where no match was identified, the appended columns will be empty.
