loadModule()

static Module* kanzi::connect::DynamicModule::loadModule ( const string  modulename, uint32_t  majorVersion, uint32_t  minorVersion  )

static

Loads and constructs a module from specific file.

Parameters

modulename	the name of the module from which the library filename is build upon.
majorVersion	major version of kanzi loading the service.
minorVersion	minor version of kanzi loading the service.

Returns

newly allocated module instance or nullptr in case loading failed. NOTE: It is not possible to unload modules so everything loaded remains in memory.

lookupModules()

static vector<string> kanzi::connect::DynamicModule::lookupModules ( )

static

Searches for module from the current working directory.

Returns

vector of filenames pointing to potential modules.

serviceNameFromModuleFilename()

static string kanzi::connect::DynamicModule::serviceNameFromModuleFilename ( string  moduleFilename )

static

Tries to resolve service name from module filename.

This function expects the naming to be following "service_cluster_GL_vs2015_Debug.dll" | "libservice_cluster.so"

Parameters

moduleFilename

the module filename to be analyzed.

Returns

service name if able to resolve it. empty string if unable to do the task.

unloadModule()

static bool kanzi::connect::DynamicModule::unloadModule ( const string  modulename )

static

Unloads a module .

Parameters

modulename

the name of the module from which the library filename is build upon. return true if moulde is unloaded, otherwise false.
