    Properties

    Actor that must be registered in the bus before this actor.

    The bus this actor subscribes to.

    canHandleUndefs: boolean

    If this actor can handle undefs overlapping variable bindings.

    includeInLogs: boolean = true

    If this actor will be logged in the debugger and physical query plan logger

    isLeaf: boolean

    If this join operator will not invoke any other join or query operations below, and can therefore be considered a leaf of the join plan.

    limitEntries: number

    Can be used by subclasses to indicate the max or min number of streams that can be joined. 0 for infinity. By default, this indicates the max number, but can be inverted by setting limitEntriesMin to true.

    limitEntriesMin: boolean

    If true, the limitEntries field is a lower limit, otherwise, it is an upper limit.

    logicalType: LogicalJoinType
    mediatorJoinSelectivity: MediatorRdfJoinSelectivity
    name: string

    The name for this actor.

    {<rdf:subject>}
    
    physicalName: string
    requiresVariableOverlap?: boolean

    If this join operator must only be used for join entries with (at least partially) common variables.
