Methods

CloneOverride(Cloneable)

When overridden in derived classes, performs type-specific cloning operations for the derived class properties. This method is called by CloneCore(Cloneable) after base properties have been copied.

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

The source object to clone from.
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>)

Gets all possible group names by combining unique names from the data with calculated items. This method merges the actual data group names with any defined calculated items to provide a complete list of available groups.

Declaration
protected override IEnumerable<object> GetAllNames(IEnumerable<object> uniqueNames, IEnumerable<object> parentGroupNames)
Parameters
System.Collections.Generic.IEnumerable<System.Object> uniqueNames

The unique group names found in the actual data.
System.Collections.Generic.IEnumerable<System.Object> parentGroupNames

The parent group names in the hierarchy.
Returns
System.Collections.Generic.IEnumerable<System.Object>

A combined enumerable of unique names and calculated items.
Overrides

GroupNameFromItem(Object, Int32)

Names a group that would contain the item. DoubleGroup.

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

A DoubleGroup name for the group that would contain the item.
Overrides
