Constructor Detail

BinaryArithmeticOperatorNode

public BinaryArithmeticOperatorNode()

Method Detail

init

public void init(java.lang.Object leftOperand,
                 java.lang.Object rightOperand)

Initializer for a BinaryArithmeticOperatorNode

Overrides:

init in class QueryTreeNode

Parameters:

leftOperand - The left operand

rightOperand - The right operand

setNodeType

public void setNodeType(int nodeType)

Description copied from class: QueryTreeNode

Set the node type for this node.

Overrides:

setNodeType in class QueryTreeNode

Parameters:

nodeType - The node type.

Returns:

Nothing.

bindExpression

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

Bind this operator

Overrides:

bindExpression in class BinaryOperatorNode

Parameters:

fromList - The query's FROM list

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
