Overview

TROClassFactory forms the base class of all class factories provided with RemObjects SDK.

Use Case

Class factories are used to register and instantiate service classes to be available for remote requests.

This is usually done by creating a new instance of a class factory in the implementation section of the service's unit by code that is auto-generated from your RODL file.

destructor Destroy
CreateInstance   protected virtual
procedure CreateInstance(const aClientID: TGUID; out anInstance: IInterface) Parameters: aClientID: anInstance:
GetAliasNames   protected
function GetAliasNames: TStringList
GetInterfaceName   protected
function GetInterfaceName: string
GetInvoker   protected
function GetInvoker: IROInvoker
IsInterfaceNameSupported   protected
function IsInterfaceNameSupported(const anInterfaceName: string): Boolean Parameters: anInterfaceName:
RegisterInterfaceName   protected
procedure RegisterInterfaceName(const anInterfaceName: string) Parameters: anInterfaceName:
ReleaseInstance   protected virtual
Called whenever a Service instance previously acquired via CreateInstance has finished processing a request. Whether the service instance is actually destroyed or saved for future use will depend on the type of class factory. procedure ReleaseInstance(const aClientID: TGUID; var anInstance: IInterface) Parameters: aClientID: anInstance:
UnregisterInterfaceName   protected
procedure UnregisterInterfaceName(const anInterfaceName: string) Parameters: anInterfaceName:
