Detailed Description

manages the loading of Qore modules from feature or path names. Also manages adding module changes into QoreProgram objects.

in the case that a QoreProgram object is created before a module is loaded externally (either through another QoreProgram object or through a direct call to the appropriate ModuleManager function), if the QoreProgram object then requests the feature, the ModuleManager will load in all namespace (class, constant, etc) changes into the QoreProgram object. All members and methods are static; there will always only be one of these...

addAutoModuleDir()

static DLLEXPORT void ModuleManager::addAutoModuleDir ( const char *  dir )

static

no longer supported - removed for security reasons

this function will abort() in debug builds, does nothing in production builds

Since

qore 0.8.4 support for auto module directories was removed

addAutoModuleDirList()

static DLLEXPORT void ModuleManager::addAutoModuleDirList ( const char *  strlist )

static

no longer supported - removed for security reasons

this function will abort() in debug builds, does nothing in production builds

Since

qore 0.8.4 support for auto module directories was removed

addModuleDir()

static DLLEXPORT void ModuleManager::addModuleDir ( const char *  dir )

static

to add a single directory to the QORE_MODULE_DIR list, can only be called before the library initialization function qore_init()

Parameters

dir	the directory path to add to the list

addModuleDirList()

static DLLEXPORT void ModuleManager::addModuleDirList ( const char *  strlist )

static

to add a list of directories separated by ':' characters to the QORE_MODULE_DIR list, can only be called before the library initialization function qore_init()

Parameters

strlist

a list of directories separated by ':' characters to add to the QORE_MODULE_DIR list

parseLoadModule()

static DLLEXPORT QoreStringNode* ModuleManager::parseLoadModule ( const char *  name, QoreProgram *  pgm = 0  )

static

loads the named module at parse time (or before run time, even if parsing is not active), returns a non-0 QoreStringNode pointer if an error occured, caller owns the QoreStringNode pointer's reference count returned if non-0

if the feature is already loaded, then the function returns immediately without raising an error The feature's namespace changes are added to the QoreProgram object if the feature is loaded and the pgm argument is non-zero.

Parameters

name	can be either a feature name or the full path to the module file
pgm	the QoreProgram object in which to include all module additions (namespaces, classes, constants, etc) immediately

runTimeLoadModule() [1/2]

static DLLEXPORT int ModuleManager::runTimeLoadModule ( const char *  name, ExceptionSink *  xsink  )

static

loads the named module at run time, returns -1 if an exception was raised, 0 for OK

If the feature is already loaded, then the function returns immediately without raising an error. The feature's namespace changes are added to the QoreProgram object if the feature is loaded.

Parameters

name	can be either a feature name or the full path to the module file
xsink	if any errors are encountered loading the module, then a Qore-language "LOAD-MODULE-ERROR" exception is raised here

Returns

-1 if an exception was raised, 0 for OK

runTimeLoadModule() [2/2]

static DLLEXPORT int ModuleManager::runTimeLoadModule ( const char *  name, QoreProgram *  pgm, ExceptionSink *  xsink  )

static

loads the named module at run time, returns -1 if an exception was raised, 0 for OK

If the feature is already loaded, then the function returns immediately without raising an error. The feature's namespace changes are added to the QoreProgram object if the feature is loaded.

Parameters

name	can be either a feature name or the full path to the module file
pgm	the QoreProgram object in which to include all module additions (namespaces, classes, constants, etc) immediately
xsink	if any errors are encountered loading the module, then a Qore-language "LOAD-MODULE-ERROR" exception is raised here

Returns

-1 if an exception was raised, 0 for OK
