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).

GetValue()

Gets a presentation friendly value of the results in the current AggregateValue.

Declaration
public object GetValue()
Returns
System.Object

Returns an object containing a formatted value or error object.

GetValueOverride()

Gets a presentation friendly value of the results in the current AggregateValue instance to be returned in GetValue(). If an error occurred during calculations the GetValue() will not call GetValueOverride() but return the error instead.

Declaration
protected abstract object GetValueOverride()
Returns
System.Object

A result object.

MergeOverride(AggregateValue)

Merge the results of an AggregateValue with the results in the current AggregateValue instance.

Declaration
protected abstract void MergeOverride(AggregateValue childAggregate)
Parameters
AggregateValue childAggregate

The AggregateValue to merge.
