About
The Metalama.Patterns.Immutability implements the concept of immutable type, i.e. types whose value cannot be changed after they have been created. Other packages, such as Metalama.Patterns.Observability, can then rely on this concept to achieve a better understanding of the code.
Key Features
- You can mark types as immutable using the
[Immutable]custom attribute or theConfigreImmutabilityfabric extension warning. - Concept of shallow or deep immutability.
- The
[Immutable]aspect reports warnings if some fields or properties are not mutable.
Main Types
The primary types in this package are:
ImmutabilityKindrepresents the kind of immutability of a type, i.e.None,ShalloworDeep.ImmutableAttributeis an aspect that marks a type as immutable and reports warnings if some fields or properties are mutable.ImmutabilityExtensions.GetImmutabilityis an extension ofINamedTypeto get theImmutabilityKindof a given type.ImmutabilityConfigurationExtensions.ConfigureImmutabilityis a fabric extension method to programmatically set theImmutabilityKindof types.IImmutabilityClassifieris an abstraction whose implementations can be passed toImmutabilityConfigurationExtensions.ConfigureImmutabilityto dynamically return theImmutabilityKindof a kind. It is useful when theImmutabilityKinddepends on type arguments.
