Methods

CloneCore(Cloneable)

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

Declaration
protected override 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).

CreateAggregate(IAggregateContext)

Creates an AggregateValue supported by that AggregateFunction.

Declaration
protected override AggregateValue CreateAggregate(IAggregateContext context)
Parameters
IAggregateContext context

AggregateContext containing information about AggregateValue usage.
Returns
AggregateValue

An AggregateValue.
Overrides

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.

Equals(Object)

Declaration
public override bool Equals(object obj)
Parameters
System.Object obj

Returns
System.Boolean

GetHashCode()

Declaration
public override int GetHashCode()
Returns
System.Int32

GetStringFormat(Type, String)

Gets a string format suitable to format the value of the AggregateValues produced by that AggregateFunction.

Declaration
public override string GetStringFormat(Type dataType, string format)
Parameters
System.Type dataType

The type of the data items.
System.String format

A string format selected by other means. You may keep or discard it.
Returns
System.String

A string.
Overrides

ToString()

Declaration
public override string ToString()
