computeDividebyper

public static Relation computeDividebyper(Relation dividend,
                                          Relation divisor,
                                          Relation per)

                                          EvaluationException

Computes the division of 'dividend' by 'divisor' per 'per'

Parameters:

dividend - The dividend

divisor - the divisor

per - The per relation

Returns:

the division of 'dividend' by 'divisor' per 'per'

Throws:

ValidationException - if the given relation arguments do not satisfy the compatibility rules for DIVIDEBYPER

EvaluationException - If the evaluation failed for any reason

getOperatorImplementation

public final 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.
