loadConfiguration

public ConfigurationData loadConfiguration(Artifact configId)
                                    throws NoSuchConfigException,
                                           IOException,
                                           InvalidConfigException

Description copied from interface: ConfigurationStore

Loads the specified configuration into the kernel

Specified by:

loadConfiguration in interface ConfigurationStore

Parameters:

configId - the id of the configuration to load, which must be fully resolved (isResolved() == true)

Returns:

the the configuration object

Throws:

NoSuchConfigException - if the configuration is not contained in the kernel

IOException - if a problem occurs loading the configuration from the store

InvalidConfigException - if the configuration is corrupt

containsConfiguration

public boolean containsConfiguration(Artifact configId)

Description copied from interface: ConfigurationStore

Determines if the store contains a configuration with the specified ID. The configuration need not be loaded or running, this just checks whether the configuration store has the data for it.

Specified by:

containsConfiguration in interface ConfigurationStore

Parameters:

configId - the unique ID of the configuration, which must be fully resolved (isResolved() == true)

Returns:

true if the store contains the configuration

createNewConfigurationDir

public File createNewConfigurationDir(Artifact configId)
                               throws ConfigurationAlreadyExistsException

Description copied from interface: ConfigurationStore

Creates an empty directory for a new configuration with the specified configId

Specified by:

createNewConfigurationDir in interface ConfigurationStore

Parameters:

configId - the unique ID of the configuration, which must be fully resolved (isResolved() == true)

Returns:

the location of the new directory

Throws:

ConfigurationAlreadyExistsException - if the configuration already exists in this store

resolve

public Set<URL> resolve(Artifact configId,
                        String moduleName,
                        String path)
                 throws NoSuchConfigException,
                        MalformedURLException

Description copied from interface: ConfigurationStore

Locate the physical locations which match the supplied path in the given artifact/module. The path may be an Ant-style pattern.

Specified by:

resolve in interface ConfigurationStore

Parameters:

configId - the artifact to search, which must be fully resolved (isResolved() == true)

moduleName - the module name or null to search in the top-level artifact location

path - the pattern to search for within the artifact/module, which may also be null to identify the artifact or module base path

Returns:

a Set (with entries of type URL) of the matching locations

Throws:

NoSuchConfigException

MalformedURLException

exportConfiguration

public void exportConfiguration(Artifact configId,
                                OutputStream output)
                         throws IOException,
                                NoSuchConfigException

Description copied from interface: ConfigurationStore

Exports a configuration as a ZIP file.

Specified by:
