Constructor Details

TimestampOperatorNode

TimestampOperatorNode(ValueNode date,
 ValueNode time,
 ContextManager cm)

Constructor for a TimestampOperatorNode.

Parameters:

date - The date

time - The time

cm - The context manager

Method Details

bindExpression

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

Bind this expression. This means binding the sub-expressions, as well as figuring out what the return type is for this expression.

Overrides:

bindExpression in class BinaryOperatorNode

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

aggregates - The aggregate list being built as we find AggregateNodes

Returns:

The new top of the expression tree.

Throws:

StandardException - Thrown on error

generateExpression

void generateExpression(ExpressionClassBuilder acb,
 MethodBuilder mb)
                 throws StandardException

Do code generation for this binary operator.

Overrides:

generateExpression in class BinaryOperatorNode

Parameters:

acb - The ExpressionClassBuilder for the class we're generating

mb - The method the code to place the code

Throws:

StandardException - Thrown on error
