Represents the label rendered at one end of a UML relationship connector to express multiplicity.

Syntax
public class MultiplicityLabel : DiagramObject, IDiagramObject, ICloneable
Remarks

The MultiplicityLabel class defines the cardinality of relationships between UML elements. It is used within ClassifierMultiplicity to represent the source and target multiplicities of a connector.

The multiplicity is typically displayed in UML notation such as 1, 0..1, or 0..*. These values are derived from LowerBounds and UpperBounds.

Examples
connectors.Add(new Connector()
{
    SourcePoint = new DiagramPoint() { X = 100, Y = 200 },
    TargetPoint = new DiagramPoint() { X = 300, Y = 200 },
    Type = ConnectorSegmentType.Straight,
    Shape = new RelationShip()
    {
        RelationshipShape = Relationship.Association,
        Multiplicity = new ClassifierMultiplicity()
        {
            Source = new MultiplicityLabel()
            {
                LowerBounds = "1",
                UpperBounds = "1"
            },
            Target = new MultiplicityLabel()
            {
                LowerBounds = "0",
                UpperBounds = "*"
            }
        }
    }
});

Constructors

MultiplicityLabel()

Initializes a new instance of MultiplicityLabel.

Declaration
public MultiplicityLabel()

MultiplicityLabel(MultiplicityLabel)

Initializes a new instance of MultiplicityLabel copied from src.

Declaration
public MultiplicityLabel(MultiplicityLabel src)
Parameters
Type Name Description
MultiplicityLabel src

Properties

LowerBounds

Specifies the lower bound of the multiplicity (e.g., "0", "1").

Declaration
[JsonPropertyName("lowerBounds")]
public string LowerBounds { get; set; }
Property Value
Type Description
string

A string representing the minimum number of instances.
Remarks

This property defines the minimum number of elements allowed in the relationship. Common values include "0", "1", etc.

Examples

This example demonstrates setting the lower bound of a multiplicity:

connectors.Add(new Connector()
{
    ID = "connector2",
    SourcePoint = new DiagramPoint() { X = 100, Y = 250 },
    TargetPoint = new DiagramPoint() { X = 300, Y = 250 },
    Shape = new RelationShip()
    {
        RelationshipShape = Relationship.Dependency,
        Multiplicity = new ClassifierMultiplicity()
        {
            Source = new MultiplicityLabel() { LowerBounds = "1" },
            Target = new MultiplicityLabel() { LowerBounds = "0", UpperBounds = "*" }
        }
    }
});

UpperBounds

Specifies the upper bound of the multiplicity (e.g., "1", "*").

Declaration
[JsonPropertyName("upperBounds")]
public string UpperBounds { get; set; }
Property Value
Type Description
string

A string representing the maximum number of instances.
Remarks

This property defines the maximum number of elements allowed in the relationship. Common values include "1" for a single instance or "*" for unlimited.

When specified along with LowerBounds, the multiplicity is displayed in the format LowerBounds..UpperBounds.

Examples

This example demonstrates setting both lower and upper bounds:

connectors.Add(new Connector()
{
    ID = "connector3",
    SourcePoint = new DiagramPoint() { X = 150, Y = 300 },
    TargetPoint = new DiagramPoint() { X = 350, Y = 300 },
    Shape = new RelationShip()
    {
        RelationshipShape = Relationship.Association,
        Multiplicity = new ClassifierMultiplicity()
        {
            Source = new MultiplicityLabel()
            {
                LowerBounds = "1",
                UpperBounds = "1"
            },
            Target = new MultiplicityLabel()
            {
                LowerBounds = "0",
                UpperBounds = "*"
            }
        }
    }
});
