Method Detail

getInstance

public static AggregationOperatorImplementation getInstance(Heading heading,
                                                            java.util.LinkedList<NameIdentifier> treatAsRange)

Gets an instance of the operator for the given heading and USING<> attributes

Parameters:

heading - The heading

treatAsRange - The USING<> attributes

Returns:

an instance of the operator for the given heading and USING<> attributes

getOperatorImplementation

public final AggregationOperatorImplementation getOperatorImplementation(OperatorGeneratorArgument[] args)
                                                                  throws NotFoundException

Description copied from interface: OperatorGenerator

Gets an implementation instance of the operator.

Specified by:

getOperatorImplementation in interface OperatorGenerator

Parameters:

args - The arguments from which the instance is to be created. There must be exactly as many arguments as there are elements in the list returned from OperatorGenerator.getOperatorGeneratorSignature(). The correspondence between OperatorGeneratorArgumentType values and OperatorGeneratorArgument types is given in the table below :

correspondence between OperatorGeneratorArgumentType values and OperatorGeneratorArgument types

OperatorGeneratorArgumentType value	OperatorGeneratorArgument type
EXPRESSION	NonScalarOperatorGeneratorExpressionArgument
EXPRESSIONWITHSCOPE	NonScalarOperatorGeneratorExpressionArgument
STRING	NonScalarOperatorGeneratorTextArgument

Returns:

an instance of the operator

Throws:

NotFoundException - If the given OperatorGeneratorArguments do not satisfy all of the rules of the OperatorGenerator. These rules are specific to each OperatorGenerator.
