Parameters

type	The type to get the driver for.

Returns: The active driver.

◆ GetDriversInfo()

void DriverFactoryBase::GetDriversInfo ( std::back_insert_iterator< std::string > & output_iterator )

static

Build a human readable list of available drivers, grouped by type.

Parameters

output_iterator The iterator to write the string to.

Definition at line 219 of file driver.cpp.

Parameters

type	The type of driver to get the name of.

Returns: The name of the type.

Definition at line 95 of file driver.h.

Referenced by DriverFactoryBase(), GetDriversInfo(), SelectDriverImpl(), and ~DriverFactoryBase().

◆ SelectDriver()

void DriverFactoryBase::SelectDriver	(	const std::string &	name,
		Driver::Type	type
	)

static

Find the requested driver and return its class.

Parameters

name	the driver to select.
type	the type of driver to select

Postcondition: Sets the driver so GetCurrentDriver() returns it too.

Definition at line 88 of file driver.cpp.

References name, SelectDriverImpl(), and type.

◆ SelectDriverImpl()

bool DriverFactoryBase::SelectDriverImpl	(	const std::string &	name,
		Driver::Type	type

staticprivate

Find the requested driver and return its class.

Parameters

name	the driver to select.
type	the type of driver to select

Postcondition: Sets the driver so GetCurrentDriver() returns it too.

Returns: True upon success, otherwise false.
