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.
