Methods

CloneCore(Cloneable)

Makes the instance a clone (deep copy) of the specified Cloneable.

Declaration
protected override sealed void CloneCore(Cloneable source)
Parameters
Cloneable source

The object to clone.
Overrides
Remarks

Notes to Inheritors If you derive from Cloneable, you may 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).

CloneOverride(Cloneable)

Makes the instance a clone (deep copy) of the specified Cloneable.

Declaration
protected abstract void CloneOverride(Cloneable source)
Parameters
Cloneable source

The object to clone.
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).
