Method Detail

init

public void init(java.lang.Object arg1,
                 java.lang.Object arg2)
          throws StandardException

Initializer. QueryTreeNode override.

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

arg1 - The window definition or reference

arg2 - aggregate function node

Throws:

StandardException

bindExpression

public ValueNode bindExpression(FromList fromList,
                                SubqueryList subqueryList,
                                java.util.List aggregateVector)
                         throws StandardException

ValueNode override.

Overrides:

bindExpression in class WindowFunctionNode

Parameters:

fromList - The FROM list for the query this expression is in, for binding columns.

subqueryList - The subquery list being built as we find SubqueryNodes

aggregateVector - The aggregate vector being built as we find AggregateNodes

Returns:

The new top of the expression tree.

Throws:

StandardException - Thrown on error

ValueNode.bindExpression(org.apache.derby.impl.sql.compile.FromList, org.apache.derby.impl.sql.compile.SubqueryList, java.util.List)

printSubNodes

public void printSubNodes(int depth)

QueryTreeNode override. Prints the sub-nodes of this object.

Overrides:

printSubNodes in class WindowFunctionNode

Parameters:

depth - The depth of this node in the tree
