Method Detail

connect

public final void connect(String reponame,
                          AbstractRepository repository)
                   throws AnalysisConfigurationException

Description copied from interface: IPlugin

Connects the given repository to this plugin via the given name. DO NOT USE THIS METHOD! Use AnalysisController.connect instead!

Specified by:

connect in interface IPlugin

Parameters:

reponame - The name of the port to connect the repository.

repository - The repository which should be used.

Throws:

AnalysisConfigurationException - if the repository-port is invalid, the repository itself is incompatible or the port is already used.

connect

public static final void connect(AbstractPlugin src,
                                 String outputPortName,
                                 AbstractPlugin dst,
                                 String inputPortName)
                          throws AnalysisConfigurationException

This method connects two plugins. DO NOT USE THIS METHOD! Use AnalysisController.connect instead!

Parameters:

src - The source plugin.

outputPortName - The output port of the source plugin.

dst - The destination plugin.

inputPortName - The input port of the destination port.

Throws:

AnalysisConfigurationException - if any given plugin is invalid, any output or input port doesn't exist or if they are incompatible. Furthermore the destination plugin must not be a reader.

isConnectionAllowed

public static final boolean isConnectionAllowed(AbstractPlugin src,
                                                String output,
                                                AbstractPlugin dst,
                                                String input)

This method checks whether two plugins can be connected.

Parameters:

src - The source plugin.

output - The output port of the source plugin.

dst - The destination plugin.

input - The input port of the destination port.

Returns:

true if and only if both given plugins are valid, the output and input ports exist and if they are compatible. Furthermore the destination plugin must not be a reader.

getName

public final String getName()

Description copied from interface: IPlugin

This method delivers the current name of this plugin instance. The name does not have to be unique.

Specified by:

getName in interface IPlugin

Returns:

The current name of the plugin instance.

getPluginName

public final String getPluginName()

Description copied from interface: IPlugin

This method delivers the plugin name of this plugin. The name should be unique, e.g., the classname.

Specified by:

getPluginName in interface IPlugin

Returns:

The name of the plugin.

getPluginDescription

public final String getPluginDescription()

Description copied from interface: IPlugin

This method delivers the description of this plugin type.

Specified by:

getPluginDescription in interface IPlugin

Returns:

The description of the plugin type.

areAllRepositoryPortsConnected

public final boolean areAllRepositoryPortsConnected()

This method checks whether all repository ports of the current plugin are connected.

Returns:

true if and only if all plugin ports (defined in the annotation) are connected to a repository.

getCurrentRepositories

public final Map<String,AbstractRepository> getCurrentRepositories()

Description copied from interface: IPlugin

This method delivers an array of AbstractRepository containing the current repositories of this instance. In other words: The constructor should be able to use the given object to initialize a new instance of this class with the same intern properties.

Specified by:

getCurrentRepositories in interface IPlugin

Returns:

An (possible empty) array of repositories.

getAllOutputPortNames

public final String[] getAllOutputPortNames()

Specified by:

Specified by:

getConnectedPlugins in interface IPlugin

Parameters:

outputPortName - The name of the output port.

Returns:
