public class CastFunctionNode
extends AbstractSelectExpression
implements FunctionNode

Represents a cast function call. We handle this specially because its type argument has a semantic meaning to the HQL query (its not just pass through).

public CastFunctionNode()
Method Detail


public void resolve(boolean inSelect)
Called from the hql-sql grammar after the children of the CAST have been resolved.

inSelect - Is this call part of the SELECT clause?


public SQLFunction getSQLFunction()
Specified by:
getSQLFunction in interface FunctionNode


public Type getFirstArgumentType()
Specified by:
getFirstArgumentType in interface FunctionNode


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
i - The index of the select expression in the projection list.
antlr.SemanticException - if a semantic error occurs
