ExtensionsRepository

Methods

AddExtension<TResult>(IExtension, ExtensionArguments, Func<IExtension, object, ExtensionArguments, object>)

Add an extension to the repository

Declaration

public TResult AddExtension<TResult>(IExtension extension, ExtensionArguments arguments, Func<IExtension, object, ExtensionArguments, object> instanceCreator) where TResult : class

Parameters

Type	Name	Description
IExtension	extension	The extension object
ExtensionArguments	arguments	The arguments required by the instance creator for the extension instance initialization
Func<IExtension, object, ExtensionArguments, object>	instanceCreator	A delegate passed to initialize a custom extension instance which will get the extension object, default extension instance and the extension initializer arguments

Returns

Type	Description
TResult	The instance created and stored in the repository or an assignable instance already present in the repository.

Type Parameters

Name	Description
TResult	The instance which is stored or was created while storing.

FirstOrDefault(Func<ExtensionStoreItem, bool>)

Returns the first element stored in the repository that satisfies a condition or a default value if no such element found.

Declaration

public ExtensionStoreItem FirstOrDefault(Func<ExtensionStoreItem, bool> predicate)

Parameters

Type	Name	Description
Func<ExtensionStoreItem, bool>	predicate	The predicate used for the searching inside the repository.

Returns

Type	Description
ExtensionStoreItem	Returns the first element stored in the repository that contains the instance reference.

FirstOrDefault(object)

Returns the first element stored in the repository that contains the extension instance reference.

Declaration

public ExtensionStoreItem FirstOrDefault(object extensionInstanceReference)

Parameters

Type	Name	Description
object	extensionInstanceReference	The extension instance reference which is searched in the repository

Returns

Type	Description
ExtensionStoreItem	Returns the first element stored in the repository that contains the instance reference.

GetAssignableInstanceOrDefault<TResult>(IExtension)

Returns an extension instance from the repository which can be assigned to a specified TResult type or null if none was found.

Declaration

public TResult GetAssignableInstanceOrDefault<TResult>(IExtension extension) where TResult : class

Parameters

Type	Name	Description
IExtension	extension	The extension instance for which the search is done.

Returns

Type	Description
TResult	Returns the extension instance assignable to TResult.

Type Parameters

Name	Description
TResult	The assignable instance type which is required from the extension store.

GetAssignableInstanceOrDefault<TResult>(Type, Type)

Returns an extension instance from the repository which can be assigned to a specified TResult type or null if none was found.

Declaration

public TResult GetAssignableInstanceOrDefault<TResult>(Type extensionAttributeType, Type extensionType) where TResult : class

Parameters

Type	Name	Description
Type	extensionAttributeType	The type for an attribute decorating the extension for which the search is done.
Type	extensionType	The extension type for which the search is done.

Returns

Type	Description
TResult	Returns the extension instance assignable to TResult.

Type Parameters

Name	Description
TResult	The assignable instance type which is required from the extension store.

GetAssignableInstanceOrDefault<TAttribute, TExtensionType, TResult>()

Returns an extension instance from the repository which can be assigned to a specified TResult type or null if none was found

Declaration

public TResult GetAssignableInstanceOrDefault<TAttribute, TExtensionType, TResult>() where TAttribute : ExtensionAttribute where TResult : class

Returns

Type	Description
TResult	Returns the extension instance assignable to TResult.

Type Parameters

Name	Description
TAttribute	The extension attribute type for which the search is done.
TExtensionType	The extension type for which the search is done.
TResult	The assignable instance type which is required from the extension store.
