Execution node that performs a nested iteration over all child nodes. Each child node under this node typically represents a table lookup. The implementation 'hops' from the first child to the next recursively for each row returned by a child. It passes a 'prototype' row (prefillPath) to each new child which contains the current partial event set.

The following tables list the members exposed by the NestedIterationExecNode type.

Public Methods

  NameDescription
AddChildNode
Adds the child node.

Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
GetHashCode
Serves as a hash function for a particular type. GetHashCode() is suitable for use in hashing algorithms and data structures like a hash table.
(Inherited from Object.)
GetType
Gets the Type of the current instance.
(Inherited from Object.)
Print
Output the execution strategy.
(Overrides .Print(IndentWriter).)
Process
Process single event using the prefill events to compile lookup results.
(Overrides .Process(EventBean, EventBean[](), IList<(Of EventBean[]()>)).)
ToString
Returns a String that represents the current Object.
(Inherited from Object.)

Protected Methods

  NameDescription
Finalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
RecursiveNestedJoin
Recursive method to run through all child nodes and, for each result set tuple returnedby a child node, execute the inner child of the child node until there are no inner child nodes.

Public Constructors

  NameDescription
NestedIterationExecNodeNew
Initializes a new instance of the NestedIterationExecNode class.
