Method Summary

Modifier and Type	Method and Description
void	accept(TParseTreeVisitor v) Accept a visitor
void	acceptChildren(TParseTreeVisitor v) Accept a visitor to iterate this class and sub-nodes of this class
void	addResultColumn(String ptext) Used to add a result column manually when re-construct a select list There must exist at least one column in column list in order to this function.
void	addResultColumn(TResultColumn resultColumn) Add a ResultColumn to the list
TSourceToken	getEndToken() The last token of the node
TResultColumn	getResultColumn(int position) Get a ResultColumn from a column position (0-based) in the list
TSourceToken	getStartToken() In teradata, the whole result column can be null, so this result column should be ingored when get start token in result column list.

Parameters:

ptext -

addResultColumn

public void addResultColumn(TResultColumn resultColumn)

Add a ResultColumn to the list

Parameters:

resultColumn - The ResultColumn to add to the list

getResultColumn

public TResultColumn getResultColumn(int position)

Get a ResultColumn from a column position (0-based) in the list

Parameters:

position - The ResultColumn to get from the list (1-based)

Returns:

the column at that position.

getStartToken

public TSourceToken getStartToken()
