### BinaryArithmeticOperatorNode

    public BinaryArithmeticOperatorNode()

Method Detail

### initialize

    public void initialize()
                    throws antlr.SemanticException

  Description copied from interface: `OperatorNode`
  Called by the tree walker during hql-sql semantic analysis after the operator sub-tree is completely built.

  Specified by:
    `initialize` in interface `OperatorNode`
  Throws:
    `antlr.SemanticException`

### getDataType

    public Type getDataType()

  Figure out the type of the binary expression by looking at the types of the operands. Sometimes we don't know both types, if, for example, one is a parameter.

  Specified by:
    `getDataType` in interface `OperatorNode`
  Specified by:
    `getDataType` in interface `SelectExpression`
  Overrides:
    `getDataType` in class `SqlNode`
  Returns:
    The expression's data type.

### setScalarColumnText

    public void setScalarColumnText(int i)
                             throws antlr.SemanticException

  Description copied from interface: `SelectExpression`
  Appends AST nodes that represent the columns after the current AST node. (e.g. 'as col0_O_')

  Specified by:
    `setScalarColumnText` in interface `SelectExpression`
  Parameters:
    `i` - The index of the select expression in the projection list.
  Throws:
    `antlr.SemanticException` - if a semantic error occurs

### getLeftHandOperand

    public Node getLeftHandOperand()

  Retrieves the left-hand operand of the operator.

  Specified by:
    `getLeftHandOperand` in interface `BinaryOperatorNode`
  Returns:
    The left-hand operand

### getRightHandOperand

    public Node getRightHandOperand()

  Retrieves the right-hand operand of the operator.

  Specified by:
    `getRightHandOperand` in interface `BinaryOperatorNode`
  Returns:
    The right-hand operand

### getDisplayText

    public String getDisplayText()

  Description copied from interface: `DisplayableNode`
  Returns additional display text for the AST node.

  Specified by:
    `getDisplayText` in interface `DisplayableNode`
  Returns:
    String - The additional display text.
