DataClass

Description

The DataClass allows the modeling of hierarchical complex data types and operations on them. The data class is the equivalent to a class in languages like Java or C++, but has less features. The content of a data class can always be sent via message between actors (defined as message data in a ProtocolClass).

Notation

Example: DataClass using PrimitiveTypes

DataClass DataClass1 {
    Attribute attribute1: int32    // attribute of primitive type
    Attribute attribute2: float32  // attribute of another primitive type

    // no arguments, no return value
    Operation operation1(): void '''
        user code
    '''
    // argument of primitive type, no return value
    Operation operation2(Param1: int32): void '''
        user code
    '''
    // argument of primitive type, return value of primitive type
    Operation operation3(Param1: int32): float64 '''
        user code
    '''
}

Example: DataClass using other DataClasses:

DataClass DataClass2 {
    Attribute attribute1: int32      // attribute of primitive type
    Attribute attribute2: DataClass1 // attribute of DataClass

    // arguments and return value by value
    Operation operation1(Param1: int32, Param2: DataClass1): DataClass1 '''
        user code
    '''
    // arguments and return value by reference except for primitive types
    Operation operation2(Param1: int32, Param2: DataClass1 ref): DataClass1 ref '''
        user code
    '''
}
