Constructor Details

BinaryArithmeticOperatorNode

BinaryArithmeticOperatorNode(int kind,
 ValueNode leftOperand,
 ValueNode rightOperand,
 ContextManager cm)

Constructor for a BinaryArithmeticOperatorNode

Parameters:

kind - The kind of operator

leftOperand - The left operand

rightOperand - The right operand

cm - The context manager

Method Details

bindExpression

ValueNode bindExpression(FromList fromList,
 SubqueryList subqueryList,
 List<AggregateNode> aggregates)
                  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

aggregates - The aggregate list being built as we find AggregateNodes

Returns:

The new top of the expression tree.

Throws:

StandardException - Thrown on error

isSameNodeKind

boolean isSameNodeKind(ValueNode o)

Description copied from class: ValueNode

Some node classes represent several logical node types (to reduce footprint), which we call kinds. This means that implementations of ValueNode.isEquivalent(ValueNode) cannot always just use instanceof to check if the other node represents the same kind. Hence this method needs to be overridden by all node classes that represent several kinds. This default implementation does not look at kinds. It is only called from implementations of isEquivalent.

Overrides:

isSameNodeKind in class BinaryOperatorNode

Parameters:

o - The other value node whose kind we want to compare with.

Returns:

true if this and o represent the same logical node type, i.e. kind.
