public abstract class ResultSetNode
extends QueryTreeNode

A ResultSetNode represents a result set, that is, a set of rows. It is analogous to a ResultSet in the LanguageModuleExternalInterface. In fact, code generation for a a ResultSetNode will create a "new" call to a constructor for a ResultSet.

Method Detail

copyFrom

public void copyFrom(QueryTreeNode node)
              throws StandardException

Fill this node with a deep copy of the given node.

Overrides:

copyFrom in class QueryTreeNode

Throws:

StandardException

toString

public String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class QueryTreeNode

Returns:

This object as a String

setInsertSource

public void setInsertSource()

Remember that this node is the source result set for an INSERT.

setResultColumns

public void setResultColumns(ResultColumnList newRCL)

Set the resultColumns in this ResultSetNode

Parameters:

newRCL - The new ResultColumnList for this ResultSetNode

getResultColumns

public ResultColumnList getResultColumns()

Get the resultColumns for this ResultSetNode

Returns:

ResultColumnList for this ResultSetNode

printSubNodes

public void printSubNodes(int depth)

Prints the sub-nodes of this object. See QueryTreeNode.java for how tree printing is supposed to work.

Overrides:

printSubNodes in class QueryTreeNode

Parameters:

depth - The depth of this node in the tree
