Creates a deep copy of this group description by copying core properties including sort order and group comparer. This method ensures that cloned instances maintain their grouping and sorting configuration independently.
protected override void CloneCore(Cloneable source)The source group description to clone from.
Overrides:
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).
Creates the group key expression.
protected override Expression CreateGroupKeyExpression(IEnumerable<Expression> valueExpressions)Value expressions used for generating group key.
Returns:Expression that creates group key for the given item.
Overrides:
Creates value expressions for values that will be used for generating group key expression.
protected override IEnumerable<Expression> CreateGroupKeyValuesExpressions(ParameterExpression itemExpression)The parameter expression, which will be used for grouping.
Returns:IEnumerable<Expression>
Value expressions.
Overrides:
Returns the member name for this description.
