Class RequiredLong<TSelf>

Namespace
Trellis
Assembly
Trellis.Primitives.dll

Base class for creating strongly-typed long integer value objects. Provides a foundation for large identifiers, sequence numbers, and other domain concepts represented by long integers.

public abstract class RequiredLong<TSelf> : ScalarValueObject<TSelf, long>, IComparable<ValueObject>, IComparable, IEquatable<ValueObject>, IConvertible, IFormattable where TSelf : RequiredLong<TSelf>, IScalarValue<TSelf, long>

Type Parameters

Examples

Creating a strongly-typed long identifier:

public partial class TraceId : RequiredLong<TraceId> { }

var result = TraceId.TryCreate(123456789L);

Remarks

This class extends ScalarValueObject<TSelf, T> to provide a specialized base for long-based value objects with automatic validation. When used with the partial keyword, the PrimitiveValueObjectGenerator source generator automatically creates:

  • IScalarValue<TSelf, long> implementation for ASP.NET Core automatic validation
  • TryCreate(long) - Factory method for longs (required by IScalarValue)
  • TryCreate(long?, string?) - Factory method with validation and custom field name
  • TryCreate(string?, string?) - Factory method for parsing strings with validation
  • IParsable<T> implementation (Parse, TryParse)
  • JSON serialization support via ParsableJsonConverter<T>
  • Explicit cast operator from long
  • OpenTelemetry activity tracing

Constructors

RequiredLong(long)

Initializes a new instance of the RequiredLong<TSelf> class with the specified long value.

protected RequiredLong(long value)

Parameters

value long

The long value.
