Method Detail

getInstance

public static AggregationOperatorImplementation getInstance(Heading heading)

Gets an instance of the relation XMINUS operator for the particular given heading

Parameters:

heading - The heading defining the relation type of both arguments

Returns:

An instance of the relation XMINUS operator for the particular given heading

getPlainInstance

public static XMINUS_RELATION_RELATION getPlainInstance(Heading heading)

Gets an instance of the relation XMINUS operator for the particular given heading

Parameters:

heading - The heading defining the relation type of both arguments

Returns:

An instance of the relation XMINUS operator for the particular given heading

getOperatorImplementation

public OperatorImplementation_V0105 getOperatorImplementation(OperatorGeneratorArgument[] args)
                                                       throws NotFoundException

Description copied from interface: OperatorGenerator

Gets an implementation instance of the operator.

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.
