Methods
CloneOverride(Cloneable)
Makes the instance a clone (deep copy) of the specified Cloneable.
Declaration
protected override void CloneOverride(Cloneable source)
Parameters
Cloneable
source
The object to clone. |
Overrides
Remarks
Notes to Inheritors If you derive from Cloneable, you need to override this method to copy all properties. It is essential that all implementations call the base implementation of this method (if you don't call base you should manually copy all needed properties including base properties).
CreateInstanceCore()
When implemented in a derived class, creates a new instance of the Cloneable derived class.
Declaration
protected override Cloneable CreateInstanceCore()
Returns
Cloneable
New instance for cloning. |
Overrides
Remarks
Do not call this method directly (except when calling base in an implementation). This method is called internally by the Clone() method whenever a new instance of the Cloneable is created. Notes to Inheritors. Every Cloneable derived class must implement this method. A typical implementation is to simply call the default constructor and return the result.
GetAllNames(IEnumerable<Object>, IEnumerable<Object>)
Returns all possible group keys for this instance.
Declaration
protected override IEnumerable<object> GetAllNames(IEnumerable<object> uniqueNames, IEnumerable<object> parentGroupNames)
Parameters

System.Collections.Generic.IEnumerable<System.Object>
parentGroupNames

Returns
System.Collections.Generic.IEnumerable<System.Object>
Returns all possible group keys for this instance. |
