Method Detail

rowTranslator

public final RexToLixTranslator rowTranslator()

Description copied from interface: AggAddContext

Returns a RexToLixTranslator suitable to transform the arguments.

Specified by:

rowTranslator in interface AggAddContext

Returns:

RexToLixTranslator suitable to transform the arguments

arguments

public final List<Expression> arguments()

Description copied from interface: AggAddContext

Returns Linq4j form of arguments. The resulting value is equivalent to rowTranslator().translateList(rexArguments()). This is handy if you need just operate on argument.

Specified by:

arguments in interface AggAddContext

Returns:

Linq4j form of arguments.
