Interface IValidationRule<TModel>

Namespace

EncDotNet.S100.Validation

Assembly

EncDotNet.S100.Core.dll

A single S-100 validation rule that examines an instance of TModel and yields zero or more ValidationFinding entries.

public interface IValidationRule<in TModel>

Type Parameters

TModel

The typed data model the rule operates on, typically a typed dataset projection such as S421RoutePlan, S124Dataset, or S102Dataset.

Remarks

Implementations must be pure with respect to the input — repeated evaluation of the same model with the same context must yield equivalent findings. Rules must not throw for malformed input; they should surface suspicions as findings instead. (The runner catches exceptions defensively to guarantee report aggregation even when a single rule misbehaves.)

The fluent RuleFor<TModel>(string) entry point is the recommended way to author simple property-style rules. More complex rules — for example Tier-3 rules that need to reach a sibling dataset via Services — should implement this interface directly.

Properties

DefaultSeverity

The default severity used by findings this rule emits when the rule itself does not override it per-finding.

ValidationSeverity DefaultSeverity { get; }

Property Value

ValidationSeverity

Description

Human-readable summary of the normative requirement this rule enforces. Surfaced in tooling and documentation.

string Description { get; }

Property Value

string

RuleId

Stable identifier traceable to a clause of the relevant IHO product specification (e.g. "S421-R-3.1").

string RuleId { get; }

Property Value

string

Methods

Evaluate(TModel, ValidationContext)

Evaluates the rule against model, returning all findings produced. Returns an empty sequence when no issues are found.

IEnumerable<ValidationFinding>
