Constructors

ConflictError(string, string, object)

[Obsolete("Use ConflictError.Duplicate(entity, field, value) instead — it also captures the calling step name.")]
public ConflictError(string entityName, string conflictField, object conflictValue)

Parameters

entityName string

conflictField string

conflictValue object

ConflictError(string, string?, string?, int)

public ConflictError(string message, string? callerMember = null, string? callerFile = null, int callerLine = 0)

Parameters

message string

callerMember string

callerFile string

callerLine int

Methods

Create(string)

Creates an instance of ConflictError with the given message.

public static ConflictError Create(string message)

Parameters

message string

Returns

ConflictError

CreateNew(string, ImmutableDictionary<string, object>)

Factory method for creating new instances (maintains immutability). Must be implemented by derived classes.

protected override ConflictError CreateNew(string message, ImmutableDictionary<string, object> tags)

Parameters

message string

tags ImmutableDictionary<string, object>

Returns

ConflictError

Duplicate(string, string, object, string?, string?, int)

Creates a conflict error for a duplicate field value, capturing the calling step name.

public static ConflictError Duplicate(string entityName, string conflictField, object conflictValue, string? callerMember = null, string? callerFile = null, int callerLine = 0)

Parameters

entityName string

conflictField string

conflictValue object

callerMember string

callerFile string

callerLine int

Returns

ConflictError

Duplicate<T>(string, object, string?, string?, int)

Creates a conflict error for a duplicate field value, inferring entity name from T.

public static ConflictError Duplicate<T>(string conflictField, object conflictValue, string? callerMember = null, string? callerFile = null, int callerLine = 0)

Parameters

conflictField string

conflictValue object

callerMember string

callerFile string

callerLine int

Returns

ConflictError

Type Parameters
