Operations

Introduction

Operations allow to manipulate the value of a Data Entity, or of a property of a Data Entity.

Configuration

The Type of an Operation will specialize this Component to perform that specific operation. Currently, there are five Types of operation that one can freely perform: Array Operations, to manipulate arrays; Assign Operations, to assign a value to a Simple or Free Input Data Entity (also possible if such data entity is for instance part of an array or a property of a struct); Math Operations, to perform numerical operations on suitable data entities; Condition Operation, utilized to define conditions; and String Operations, to manipulate strings.

Types

Array Operations: An Array Operation is a type of operation utilized to manipulate arrays. Next to the Primary Scope of the operation, defined in the Data Manipulation Element, an array operation presents one Term and an Operator. The Term defines what Data Entity should be used for this Array Operation. The Operator of this Array Operation defines what type of operation is performed. A Pop operation means that the Data Entity defined as First Term will be removed from the Array, whereas a Push operation means that it will be added to the Array.

Assign Operation: An Assign Operation is utilized to change the value of a suitable Data Entity by assigning it another data entity's value. The Mapping defines what Data Entity should be used to assign the value to the data entity in the Manipulation's primary scope.

Math Operation: A Math Operation is utilized to perform numerical operations on suitable data entities. Next to the Primary Scope of the operation, defined in the Data Manipulation Element, a math operation presents two Terms and an Operator. The first Term defines what Data Entity should be used as the left-hand side of this Math Operation. The second Term defines what Data Entity should be used as the right-hand side of this Math Operation. The Operator of this Math Operation defines what type of mathematical operation is performed between the two Terms. There are four possible Operators: Add, Subtract, Divide, and Multiply.

Condition Operation: A Condition Operation is a special type of operation utilized to define conditions. The first Term defines what Data Entity should be used as the left-hand side of this Condition Operation. The second Term defines what Data Entity should be used as the right-hand side of this Condition Operation. The Operator of this Condition Operation defines what type of comparison is performed between the two Terms of the condition. There are six Operators for a Condition: Less Than, Greater Than, Equal, Less Than or Equal, Greater Than or Equal, and Not Equal.

String Operation: A String Operation is utilized to manipulate strings. Next to the Primary Scope of the operation, defined in the Data Manipulation Element, a string operation presents two Terms and an Operator. The first Term defines what Data Entity should be used as the left-hand side of this String Operation. The second Term defines what Data Entity should be used as the right-hand side of this String Operation. The Operator of this String Operation defines what type of operation is performed between the two Terms. There is one possible operator: Concatenate, which is used to append the values of the two strings one after the other.
