Detailed Description

Query and set certain properties of the CppMicroServices library.

The following environment variables influence the runtime behavior of the CppMicroServices library:

  • US_DISABLE_AUTOLOADING If set, auto-loading of modules is disabled.
  • US_AUTOLOAD_PATHS A ':' (Unix) or ';' (Windows) separated list of paths from which modules should be auto-loaded.
Remarks
This class is thread safe.

Member Function Documentation

void us::ModuleSettings::AddAutoLoadPath ( const std::string &  path)
static

Add a path in the file-system to the list of paths from which modules will be auto-loaded.

Parameters
pathThe additional absolute auto-load path in the file-system.

Definition at line 159 of file usModuleSettings.cpp.

Referenced by AddMitkAutoLoadPaths().

std::string us::ModuleSettings::CURRENT_MODULE_PATH ( )
static

Returns a special string which can be used as an argument for a AddAutoLoadPath() call.

When a module is loaded and this string has been added as a path to the list of auto-load paths the CppMicroServices library will auto-load all modules from the currently being loaded module's auto-load directory.

Returns
A string to be used in AddAutoLoadPath().
Remarks
The returned string is contained in the default set of auto-load paths, unless a new set of paths is given by a call to SetAutoLoadPaths().

ModuleSettings::PathList us::ModuleSettings::GetAutoLoadPaths ( )
static
Returns
A list of paths in the file-system from which modules will be auto-loaded.

Definition at line 136 of file usModuleSettings.cpp.

MsgType us::ModuleSettings::GetLogLevel ( )
static

Get the current logging level.

Returns
The currently used logging level.

Definition at line 183 of file usModuleSettings.cpp.

std::string us::ModuleSettings::GetStoragePath ( )
static

Get the absolute path for persistent data. The returned path might be empty. If the path is non-empty, it is safe to assume that the path exists and is writable.

Returns
The absolute path to the persistent storage path.

Definition at line 171 of file usModuleSettings.cpp.

bool us::ModuleSettings::IsAutoLoadingEnabled ( )
static
Returns
true if support for module auto-loading is enabled, false otherwise.
Remarks
This method will always return false if support for auto-loading has not been configured into the CppMicroServices library or if it has been disabled by defining the US_DISABLE_AUTOLOADING environment variable.

Definition at line 119 of file usModuleSettings.cpp.

bool us::ModuleSettings::IsThreadingSupportEnabled ( )
static
Returns
true if threading support has been configured into the CppMicroServices library, false otherwise.

Definition at line 110 of file usModuleSettings.cpp.

void us::ModuleSettings::SetAutoLoadingEnabled ( bool  enable)
static

Enable or disable auto-loading support.

Parameters
enableIf true, enable auto-loading support, disable it otherwise.
Remarks
Calling this method will have no effect if support for auto-loading has not been configured into the CppMicroServices library of it it has been disabled by defining the US_DISABLE_AUTOLOADING envrionment variable.

Definition at line 130 of file usModuleSettings.cpp.

void us::ModuleSettings::SetAutoLoadPaths ( const PathList paths)
static

Set a list of paths in the file-system from which modules should be auto-loaded.

Parameters
pathsA list of absolute file-system paths.

Definition at line 148 of file usModuleSettings.cpp.

void us::ModuleSettings::SetLogLevel ( MsgType  level)
static

Set the logging level for log messages from CppMicroServices modules.

Higher logging levels will discard messages with lower priority. E.g. a logging level of WarningMsg will discard all messages of type DebugMsg and InfoMsg.

Parameters
levelThe new logging level.

Definition at line 177 of file usModuleSettings.cpp.

void us::ModuleSettings::SetStoragePath ( const std::string &  path)
static

Set a local storage path for persistend module data.

This path is used as a base directory for providing modules with a storage path for writing persistent data. The callee must ensure that the provided path exists and is writable.

See also
ModuleContext::GetDataFile(const std::string&)
Parameters
pathAn absolute path for writing persistent data.
