About
The Metalama.Patterns.Observability contains an aspect that implements the Observer pattern, i.e. the INotifyPropertyChanged interface.
Key Features
- Supports automatic properties, explicit properties (including field-backed properties).
- Supports child objects, i.e. properties like
string FullName => $"{this.Model.FirstName} {this.Model.LastName}". - Idiomatic. Does not require you to change your coding patterns (unlike the MVVM community toolkit).
- Safe. Reports warnings when a property dependency is not understood.
Main Types
The primary types in this package are:
ObservableAttributeis a type-level aspect that implements the Observer pattern and theINotifyPropertyChangedinterface.NotObservableAttributeis an attribute that waives a property from theObservableAttributeaspect.ConstantAttributeis an attribute that represents that a method is safed for use from a property made observable by theObservableAttributeaspect.SuppressObservabilityWarningsAttributeis an attribute that suppresses all warnings reported by theObservableAttributeaspect in the target property.ObservabilityExtensions.ConfigureObservabilityis a fabric extension method that allows to configure theObservableAttributeaspect.
