Method Detail

loadConfigurations

GridBiTuple<Collection<GridConfiguration>,? extends GridSpringResourceContext> loadConfigurations(URL cfgUrl,
                                                                                                String... excludedProps)
                                                                                                  throws GridException

Loads all grid configurations specified within given configuration file.

Usually Spring XML configuration file will contain only one Grid definition. Note that Grid configuration bean(s) is retrieved form configuration file by type, so the name of the Grid configuration bean is ignored.

Parameters:

cfgUrl - Configuration file path or URL. This cannot be null.

excludedProps - Properties to exclude.

Returns:

Tuple containing all loaded configurations and Spring context used to load them.

Throws:

GridException - If grid could not be started or configuration read. This exception will be thrown also if grid with given name has already been started or Spring XML configuration file is invalid.

loadBeans

Map<Class<?>,Object> loadBeans(URL cfgUrl,
                             Class<?>... beanClasses)
                               throws GridException

Loads bean instances that match the given types from given configuration file.

Parameters:

cfgUrl - Configuration file path or URL. This cannot be null.

beanClasses - Beans classes.

Returns:

Bean class -> loaded bean instance map, if configuration does not contain bean with required type the map value is null.

Throws:

GridException - If failed to load configuration.

userVersion

String userVersion(ClassLoader ldr,
                 GridLogger log)

Gets user version for given class loader by checking META-INF/gridgain.xml file for userVersion attribute. If gridgain.xml file is not found, or user version is not specified there, then default version (empty string) is returned.

Parameters:

ldr - Class loader.

log - Logger.

Returns:

User version for given class loader or empty string if no version was explicitly specified.
