All Implemented Interfaces:

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).

CastFunctionNode

public CastFunctionNode()

Method Detail

resolve

public void resolve(boolean inSelect)

Called from the hql-sql grammar after the children of the CAST have been resolved.

Parameters:

inSelect - Is this call part of the SELECT clause?

getSQLFunction

public SQLFunction getSQLFunction()

Specified by:

getSQLFunction in interface FunctionNode

getFirstArgumentType

public Type getFirstArgumentType()

Specified by:

getFirstArgumentType in interface FunctionNode

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
