C# Class Catel.IoC.TypeFactory

Type factory which will cache constructors to ensure the best performance available. This class will automatically watch the IServiceLocator.TypeRegistered event and clear the cache automatically when the event occurs.

Inheritance: ITypeFactory

Public Methods

Method	Description
ClearCache ( ) : void	Clears the cache of all constructors. This call is normally not necessary since the type factory should keep an eye on the IServiceLocator.TypeRegistered event to invalidate the cache.
CreateInstance ( Type typeToConstruct ) : object	Creates an instance of the specified type using dependency injection.
CreateInstanceWithParameters ( Type typeToConstruct ) : object	Creates an instance of the specified type using the specified parameters as injection values.
CreateInstanceWithParametersAndAutoCompletion ( Type typeToConstruct ) : object	Creates an instance of the specified type using the specified parameters as injection values. This method will also auto-complete any additional dependencies that can be resolved from the IServiceLocator.
CreateInstanceWithParametersAndAutoCompletionWithTag ( Type typeToConstruct, object tag ) : object	Creates an instance of the specified type using the specified parameters as injection values. This method will also auto-complete any additional dependencies that can be resolved from the IServiceLocator.
CreateInstanceWithParametersWithTag ( Type typeToConstruct, object tag ) : object	Creates an instance of the specified type using the specified parameters as injection values.
CreateInstanceWithTag ( Type typeToConstruct, object tag ) : object	Creates an instance of the specified type using dependency injection.
TypeFactory ( IServiceLocator serviceLocator ) : System	Initializes a new instance of the TypeFactory class.

Private Methods

Method	Description
CanConstructorBeUsed ( ConstructorInfo constructor, object tag, bool autoCompleteDependencies ) : bool	Determines whether the specified constructor can be used for dependency injection.
CloseCurrentTypeIfRequired ( Catel.IoC.TypeRequestInfo typeRequestInfoForTypeJustConstructed ) : void	Marks the specified type as not being created. If this was the only type being constructed, the type request path will be closed.
CompleteTypeRequestPathIfRequired ( Catel.IoC.TypeRequestInfo typeRequestInfoForTypeJustConstructed ) : void	Completes the type request path by checking if the currently created type is the same as the first type meaning that the type is successfully created and the current type request path can be set to `null`.
CountSpecialObjects ( ConstructorInfo constructor ) : int	Gets the special objects count for the specific constructor.
CreateInstanceWithSpecifiedParameters ( Type typeToConstruct, object tag, object parameters, bool autoCompleteDependencies, bool preventCircularDependencies = true ) : object	Creates an instance of the specified type using the specified parameters as injection values.
GetConstructorCache ( bool autoCompleteDependencies ) : ConstructorInfo>.Dictionary	Gets the constructor cache depending on whether the dependencies should be auto completed.
GetTypeMetaData ( Type type ) : TypeMetaData	Gets the constructors metadata.
InitializeAfterConstruction ( object obj ) : void	Initializes the created object after its construction.
IsValidParameterValue ( Type parameterType, object parameterValue ) : bool	Determines whether the specified parameter value can be used for the specified parameter type.
OnAssemblyLoaded ( object sender, AssemblyLoadedEventArgs e ) : void	Called when the TypeCache.AssemblyLoaded event occurs.
OnServiceLocatorTypeRegistered ( object sender, Catel.IoC.TypeRegisteredEventArgs eventArgs ) : void	Called when the IServiceLocator.TypeRegistered event occurs.
TryCreateToConstruct ( Type typeToConstruct, ConstructorInfo constructor, object tag, object parameters, bool checkConstructor, bool hasMoreConstructorsLeft ) : object	Tries to create the service with the specified constructor using the specified parameters. This method will not throw an exception when the invocation fails. Note that this method does not require an implementation of TypeRequestPath because this already has the parameter values and thus cannot lead to invalid circular dependencies.
