Overview

IDADriverManager provides access to all the functionality needed to load, unload and verify drivers.

Though this interface isn't used in Data Abstract directly, it can be usable in Hydra plugins for drivers managing.

It can be obtained using a TDADriverManager component:

var
 idm:IDADriverManager;
begin
  idm :=  DriverManager as IDADriverManager;

Location

uDAInterfaces.pas

• TDADriverManager

Properties

DriverCount
Returns the number of drivers currently available, including both statically linked and dynamically loaded drivers. property DriverCount: integer read
Drivers
Returns the IDADriver reference for the specified driver. property Drivers[Index: integer]: IDADriver read

Required Methods

DriverByDriverID
function DriverByDriverID(const aDriverID: string): IDADriver Parameters: aDriverID:
FindDriver
function FindDriver(const aDriverID: string; out Driver: IDADriver): boolean Parameters: aDriverID: Driver:
GetDriverCount
Returns the number of drivers currently available, including both statically linked and dynamically loaded drivers. function GetDriverCount: integer
GetDrivers
Returns the IDADriver reference for the specified driver. function GetDrivers(Index: integer): IDADriver Parameters: Index:
ListDrivers
function ListDrivers(const aDirectory: string; out FileNames: IROStrings): integer Parameters: aDirectory: FileNames:
LoadDriver
Dynamically loads the driver from the specified .dad file. procedure LoadDriver(const aFileName: string) Parameters: aFileName:
LoadDrivers ()   overload
Dynamically loads all the drivers from the specified list of .dad files. procedure LoadDrivers
LoadDrivers (IROStrings, boolean, boolean)   overload
procedure LoadDrivers(const aDriverList: IROStrings; aIgnoreDuplicates: boolean; aIgnoreErrors: boolean) Parameters: aDriverList: aIgnoreDuplicates: aIgnoreErrors:
UnloadAllDrivers
Unloads all dynamically loaded drivers. Before calling this method, make sure that there are no active or pooled connections using the driver(s) about to be unloaded. You can ensure all pooled connections are closed by calling the TDAConnectionManager.ClearPool method. procedure UnloadAllDrivers
UnloadDriver
Unloads the specified driver, if it was dynamically loaded. Before calling this method, make sure there are no active or pooled connections using the driver(s) about to be unloaded. You can ensure all pooled connections are closed by calling the TDAConnectionManager.ClearPool method. procedure UnloadDriver(anIndex: integer) Parameters: anIndex:
