eQuantic.Linq.Specification

The classic specification pattern, rebuilt on the eQuantic.Linq.Expressions engine: composable, provider-friendly predicates with operator overloads.

using eQuantic.Linq.Specification;

var paid    = new DirectSpecification<Order>(o => o.Status == OrderStatus.Paid);
var big     = new DirectSpecification<Order>(o => o.Total > 100m);
var recent  = new DirectSpecification<Order>(o => o.CreatedAt > cutoff);

var spec = (paid & big) | !recent;          // operator overloads
var alt  = paid.AndAlso(big).OrNot(recent); // fluent equivalents

var results = orders.Where(spec.SatisfiedBy());
  • DirectSpecification, TrueSpecification, And/AndAlso, Or/OrElse, Not — parameters are rebound (no Invoke), so composed expressions stay translatable by LINQ providers such as EF.
  • Composition is powered by the engine's PredicateExtensions (eQuantic.Linq.Expressions), which offers the same AndAlso/OrElse/Not directly over Expression<Func<T, bool>> when you don't need the pattern.

Specifications from serialized payloads

ExpressionModelSpecification<T> turns a serialized expression — an ExpressionModel<T> or its raw JSON, received from another service, a queue or an API client — into a composable specification:

// payload received over the wire (lean, hand-writable format)
var spec = new ExpressionModelSpecification<Order>(json);

var query = orders.Where((spec & onlyActive).SatisfiedBy());

Everything the engine offers applies: root-anchored type inference, strict type-resolution policies for untrusted payloads (ExpressionSerializer.CreateSecure) and DTO→entity casting via a customized ExpressionSerializer. The parsed filter stays available as spec.Model for onward transport.

eQuantic.Core.Data

eQuantic Core Data Class Library
eQuantic.Linq

The eQuantic.Linq engine as a single reference: a meta-package that brings in eQuantic.Linq.Expressions (expression ⇄ JSON serialization, inference, casting), eQuantic.Linq.Web (query-string syntax and typed builders) and eQuantic.Linq.Specification (the specification pattern). Framework-free core — the ASP.NET Core / Swagger / OpenAPI integrations remain opt-in packages.
eQuantic.Linq.Web.Specification

Query-string specifications for eQuantic.Linq: build composable, reusable specifications directly from REST filter query strings (property:op(value), and/or/not, any/all, aggregates) via eQuantic.Linq.Web.
