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> uniqueNames

Enumeration of all unique group keys that were discovered after grouping.
System.Collections.Generic.IEnumerable<System.Object> parentGroupNames

Enumeration of all parent groups.
Returns
System.Collections.Generic.IEnumerable<System.Object>

Returns all possible group keys for this instance.
Overrides

GetUniqueName()

Returns the member name for this description.

Declaration
public override string GetUniqueName()
Returns
System.String

Overrides

GroupNameFromItem(Object, Int32)

Names a group that would contain the item. DayGroup. MonthGroup. QuarterGroup. YearGroup.

Declaration
protected override object GroupNameFromItem(object item, int level)
Parameters
System.Object item

The item to group.
System.Int32 level

The level of grouping for this GroupDescription.
Returns
System.Object
