GetUserData<T>(T)

Provides ad-hoc approach to associate some data with the object without modification of it.

Declaration

public static UserDataStorage GetUserData<T>(this T obj)

    where T : class

Parameters

Type	Name	Description
T	obj	Target object.

Returns

Type	Description
UserDataStorage	User data storage.

Type Parameters

Name	Description
T	The type of the object.

Remarks

This method allows to associate arbitrary user data with any object. User data storage is not a part of object type declaration. Modification of user data doesn't cause modification of internal state of the object. The storage is associated with the object reference. Any user data are transient and can't be passed across process boundaries (i.e. serialization is not supported).

IsOneOf<T>(T, T[])

Checks whether the specified object is equal to one of the specified objects.

Declaration

public static bool IsOneOf<T>(this T value, params T[] values)

    where T : class

Parameters

Type	Name	Description
T	value	The object to compare with other.
T[]	values	Candidate objects.

Returns

Type	Description
Boolean	true, if `value` is equal to one of `values`.

Type Parameters

Name	Description
T	The type of object to compare.

Remarks

This method uses Equals(Object, Object) to check equality between two objects.

IsOneOf<T>(T, IEnumerable<T>)

Checks whether the specified object is equal to one of the specified objects.

Declaration

public static bool IsOneOf<T>(this T value, IEnumerable<T> values)

    where T : class

Parameters

Type	Name	Description
T	value	The object to compare with other.
IEnumerable<T>	values	Candidate objects.

Returns

Type	Description
Boolean	true, if `value` is equal to one of `values`.

Type Parameters

Name	Description
T	The type of object to compare.

Remarks

This method uses Equals(Object, Object) to check equality between two objects.
