UnaryArithmeticNode

public UnaryArithmeticNode()
Method Detail

getDataType

public Type getDataType()
Description copied from interface: OperatorNode
Retrieves the data type for the overall operator expression.

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

initialize

public void initialize()
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

getOperand

public Node getOperand()
Description copied from interface: UnaryOperatorNode
Retrievs the node representing the operator's single operand.

Specified by:
getOperand in interface UnaryOperatorNode
Returns:
The operator's single operand.
