LookupInstructionQueryPlanNodeForge

public LookupInstructionQueryPlanNodeForge(int rootStream,
                                           String rootStreamName,
                                           int numStreams,
                                           boolean[] requiredPerStream,
                                           List<LookupInstructionPlanForge> lookupInstructions,
                                           List<BaseAssemblyNodeFactory> assemblyInstructionFactories)

Ctor.

Parameters:

rootStream - is the stream supplying the lookup event

rootStreamName - is the name of the stream supplying the lookup event

numStreams - is the number of streams

lookupInstructions - is a list of lookups to perform

requiredPerStream - indicates which streams are required and which are optional in the lookup

assemblyInstructionFactories - is the bottom-up assembly factory nodes to assemble a lookup result nodes
