Description copied from interface: RecordQueryPlan

Returns the (zero or more) RecordQueryPlan children of this plan.

Warning: This part of the API is undergoing active development. At some point in the future, the return type of this method will change to allow it to return a list of generic QueryPlans. At current, every RecordQueryPlan can only have other RecordQueryPlans as children. However, this is not guaranteed to be the case in the future. This method has been marked as API.Status#UNSTABLE as of version 2.5.

Specified by:

getChildren in interface RecordQueryPlan

Returns:
