Description copied from interface: MetadataRepository

Retrieve project references from the metadata repository. Note that this is not built into the content model for a project version as a reference may be present (due to reverse-lookup of dependencies) before the actual project is, and we want to avoid adding a stub model to the content repository.

Specified by:

getProjectReferences in interface MetadataRepository

Parameters:

repoId - the repository ID to look within

namespace - the namespace of the project to get references to

projectId - the identifier of the project to get references to

projectVersion - the version of the project to get references to

Returns:

a list of project references

Throws:

MetadataResolutionException

searchArtifacts

public List<ArtifactMetadata> searchArtifacts(String text,

                                       throws MetadataRepositoryException

This implementation just calls getArtifactsByMetadata( null, text, repositoryId ). We can't search artifacts by any property.

Specified by:

searchArtifacts in interface MetadataRepository

repositoryId - can be null to search in all repositories

exact - running an exact search, the value must exactly match the text.

Returns:

a list of artifacts

Throws:

MetadataRepositoryException

searchArtifacts

public List<ArtifactMetadata> searchArtifacts(String key,
                                              String text,
                                              String repositoryId,
                                              boolean exact)
                                       throws MetadataRepositoryException

The exact parameter is ignored as we can't do non exact searches in Cassandra

Specified by:

searchArtifacts in interface MetadataRepository

Parameters:

key - search only inside this key

repositoryId - can be null to search in all repositories

exact - running an exact search, the value must exactly match the text.

Returns:

a list of artifacts

Throws:

MetadataRepositoryException
