Member Function Documentation

TString zeus::TLibLoader::getFileName

(

)

const [inline]

Returns the file name of the library

void * zeus::TLibLoader::getLibraryHandle

(

)

const [inline]

Returns the handle of the loaded library

Retval zeus::TLibLoader::registerLibrary

(

)

Register a code module library. If this method succeeded the method unregisterLibrary().

Return values:

	RET_NOERROR	: module registered
	RET_REQUEST_FAILED	: registration failed

Retval zeus::TLibLoader::unregisterLibrary

(

bool

bLog = true

)

Unregister a code module library.

Parameters:

bLog

: using the logging

Return values:

	RET_NOERROR	: module unregistered
	RET_REQUEST_FAILED	: unregistration failed

Retval zeus::TLibLoader::createObject	(	const IString &	rClassName,
		IZUnknown *&	rpIface
	)

This method creates an object out of the codemodule

Parameters:

	rClassName	: Name of the class
	rpIface	: Reference to return

Return values:

	RET_NOERROR	: Object created
	RET_REQUEST_FAILED	: library not valid or factory function returned error
	RET_METHOD_NOT_IMPL	: method for classname not implemented

Retval zeus::TLibLoader::load

(

)

loads the Library

Return values:

	RET_NOERROR	: Library loaded
	RET_INVALID_DATA	: not able to load the library

Retval zeus::TLibLoader::unload

(

bool

bLog = true

)

Unloads the library

Parameters:

bLog

: using the logging

Return values:

	RET_NOERROR	: Library unloaded
	RET_REQUEST_FAILED	: Failed. Library was not loaded.

bool zeus::TLibLoader::isLoaded

(

)

const [inline]

Checks if the libray is loaded

Return values:

	true	: Lib is loaded
	false,:	Lib is not loaded

void * zeus::TLibLoader::getFunction

(

const TString &

rFunctName

)

Returns the pointer of a library function.

Return values:

	NULL	: Function not found
	>	NULL: Pointer of the function

Retval zeus::TLibLoader::registerXClass	(	const IString &	rClassName,
		Uint &	rHandle
	)

Register a exported function for creating an x-object. If there is a method found it will be used to create X-Objects with a configuration ClassName="rClassName" and CodeModule="Name of Library"

Parameters:

	rClassName	: class name of the X-Object
	rHandle	: Returns the handle of the method registration

Return values:

	RET_REQUEST_FAILED	: registration failed because the library is not valid or the method is already registered
	RET_NOERROR	: registration succeeded
	RET_METHOD_NOT_IMPL	: method for classname not implemented
