Class DecisionConflict

Namespace: Cratis.Chronicle.ReadModels

Assembly: Cratis.Chronicle.dll

A concurrency conflict for a protected read.

public record DecisionConflict : IEquatable<DecisionConflict>

Inheritance: object

Implements: IEquatable<DecisionConflict>

Inherited Members: object.GetType()

object.MemberwiseClone()

object.Equals(object, object)

object.ReferenceEquals(object, object)

Remarks

A conflict can be returned as a response body: System.Text.Json writes the read model's identifier, the Key and the conflicting event, if known, as plain values, with or without concept converters registered. The CLR ReadModelType is not serialized.

Constructors

DecisionConflict(DecisionConflict)

protected DecisionConflict(DecisionConflict original)

Parameters

original DecisionConflict

DecisionConflict(Type, ReadModelKey)

A concurrency conflict for a protected read.

public DecisionConflict(Type ReadModelType, ReadModelKey Key)

Parameters

ReadModelType Type: The read model that changed.
Key ReadModelKey: The key that changed.

Remarks

Properties

ConflictingEventSequenceNumber

Gets the EventSequenceNumber of the first event matching the decision's guard after the read, if known. Reads that share a guard are merged, so it can belong to another read under the same guard.

[JsonConverter(typeof(ConceptAsJsonConverterFactory))]
public EventSequenceNumber? ConflictingEventSequenceNumber { get; init; }

Property Value

EventSequenceNumber

Remarks

Null when the conflict was not caused by a reported concurrency violation, or the kernel did not report the event.

ConflictingEventTypeId

Gets the EventTypeId of the first event matching the decision's guard after the read, if known. Reads that share a guard are merged, so it can belong to another read under the same guard.

[JsonConverter(typeof(ConceptAsJsonConverterFactory))]
public EventTypeId? ConflictingEventTypeId { get; init; }

Property Value

EventTypeId

Remarks

Null when the conflict was not caused by a reported concurrency violation, or the kernel did not report the event.

EqualityContract

protected virtual Type EqualityContract { get; }

Property Value

Type

Key

The key that changed.

[JsonConverter(typeof(ConceptAsJsonConverterFactory))]
public ReadModelKey Key { get; init; }

Property Value

ReadModelKey

ReadModel

Gets the ReadModelIdentifier of the read model that changed.

[JsonConverter(typeof(ConceptAsJsonConverterFactory))]
public ReadModelIdentifier ReadModel { get; }

Property Value

ReadModelIdentifier

ReadModelType

The read model that changed.

[JsonIgnore]
public Type ReadModelType { get; init; }

Property Value
