Field Detail

JCORE_REPOSITORIES

public static final List<ComponentRepository> JCORE_REPOSITORIES

These are the GitHub locations of the JCoRe repositories, JCoRe Base and JCoRe projects. They currently serve as default repositories to choose from for the pipeline builders.

Method Detail

loadActiveRepositories

public static List<ComponentRepository> loadActiveRepositories()

Looks in the local repository JSON meta information file for currently active repositories. Found repositories are set to this class as the active repositories from which components will be offered.

getRepositories

public static Stream<ComponentRepository> getRepositories()

Returns the repositories that are currently in use, i.e. for which the JSON meta data is stored in the home directory.

Returns:

A stream of repositories currently used by the pipeline builder.

getRepositories

public static Stream<ComponentRepository> getRepositories(Predicate<ComponentRepository> filter)

Returns the repositories that are currently in use, i.e. for which the JSON meta data is stored in the home directory. The optional filter predicate may be used to only get specific repositories back.

Parameters:

filter - A filter to restrict the returned repositories.

Returns:

A - possibly filtered - stream of repositories currently used by the pipeline builder.

addRepositories

public static void addRepositories(ComponentRepository... repositories)
                            throws IOException

Loads existing repositories from the JSON file in the PipelineBuilderConstants.JcoreMeta.LOCAL_STORAGE, if it exists, and adds the given repositories. If the file does not exist, it is created and initialized with the given repositories. Note that this can be used to circumvent the addition of the JCoRe repositories when this method is called before the first call to loadActiveRepositories().

Parameters:

repositories -

Throws:

IOException

saveRepositoryConfiguration

public static void saveRepositoryConfiguration()
                                        throws IOException

Throws:

IOException

getMetaFile

public static File getMetaFile(ComponentRepository repository)

getMetaFile

public static File getMetaFile(String repositoryName,
                               String repositoryVersion)

saveMetaInformationToDisk

public static void saveMetaInformationToDisk(ComponentRepository repository)
                                      throws GithubInformationException

Throws:

GithubInformationException

hasComponentListMetaFile

public boolean hasComponentListMetaFile(ComponentRepository repository)

deleteComponentList

public static void deleteComponentList(String repositoryName,
                                       String version)
