Detailed Description

Structure is an otx:ComplexType.

A structure is a user-defined data type composed of elements that can have different data types. It is typically used to encapsulate small groups of related elements, such as the coordinates of a rectangle. Structures can contain elements of any OTX data type and also Structure itself in any depth. To define the structure of a Structure the StructureSignature is used. A Structure itself has no literal and also has no init value. To access structure elements only StepByName and not StepByIndex will be used.

Note: IMPORTANT — A Structure value can be persisted if all contained elements can be persisted, see Persistence extension.

Checker rules

CheckerRule.DataType_Chk001 - Accessing structure elements
Core.CheckerRule.Core_Chk053 - no dangling OtxLink associations
CheckerRule.DataType_Chk006 - StructureLiteral structure type matches Structure declaration structure type

Sample

package DataType.StructureSignature StructureSignature1(Boolean StructureElement1 = false, Integer StructureElement2, Float StructureElement3, String StructureElement4, ByteField StructureElement5);
// Global Declarations
public procedure main()
{
    // Local Declarations
    StructureSignature1 Structure1;
}

init

StructureLiteral OpenTestSystem.Otx.Extensions.DataType.DataTypes.Structure.init

Cardinality [0..1]
his optional element stands for the initialization of the structure at declaration time.

Note: IMPORTANT — Only structure elements which have a literal can be initialized. Note: IMPORTANT — If the Structure declaration is not explicitly initialized (omitted <init> element), the default value of each element shall be used.

structureType

OtxLink OpenTestSystem.Otx.Extensions.DataType.DataTypes.Structure.structureType

Cardinality [1]
Refers to a certain StructureSignature.
