Class SparseDirectoryTrustedChecksumsSource

java.lang.Object

org.eclipse.aether.internal.impl.checksum.FileTrustedChecksumsSourceSupport

org.eclipse.aether.internal.impl.checksum.SparseDirectoryTrustedChecksumsSource

All Implemented Interfaces:

TrustedChecksumsSource

@Singleton
@Named("sparseDirectory")
public final class SparseDirectoryTrustedChecksumsSource
extends FileTrustedChecksumsSourceSupport

Sparse file FileTrustedChecksumsSourceSupport implementation that use specified directory as base directory, where it expects artifacts checksums on standard Maven2 "local" layout. This implementation uses Artifact coordinates solely to form path from basedir, pretty much as Maven local repository does. Metadata checksums are covered as well, on the same layout, with the metadata path composed from the origin repository key (for example g/a/v/maven-metadata-central.xml.sha1).

The source by default is "origin aware", it will factor in origin repository ID as well into base directory name (for example ".checksums/central/...").

The checksums files are directly loaded from disk, so in-flight file changes during lifecycle of session are picked up. This implementation can be simultaneously used to lookup and also write checksums. The written checksums will become visible across all sessions right after the moment they were written.

The name of this implementation is "sparseDirectory".

Since:

1.9.0

Method Details

isEnabled

protected boolean isEnabled(RepositorySystemSession session)

Description copied from class: FileTrustedChecksumsSourceSupport

Returns true if session configuration marks this instance as enabled.

Default value is false.

Specified by:

isEnabled in class FileTrustedChecksumsSourceSupport

doGetTrustedArtifactChecksums

protected Map<String,String> doGetTrustedArtifactChecksums(RepositorySystemSession session,
 Artifact artifact,
 ArtifactRepository artifactRepository,
 List<ChecksumAlgorithmFactory> checksumAlgorithmFactories)

Description copied from class: FileTrustedChecksumsSourceSupport

Implementors MUST NOT return null at this point, as this source is enabled.

Specified by:

doGetTrustedArtifactChecksums in class FileTrustedChecksumsSourceSupport

doGetTrustedMetadataChecksums

protected Map<String,String> doGetTrustedMetadataChecksums(RepositorySystemSession session,
 Metadata metadata,
 ArtifactRepository artifactRepository,
 List<ChecksumAlgorithmFactory> checksumAlgorithmFactories)

Description copied from class: FileTrustedChecksumsSourceSupport

Implementors MUST NOT return null at this point, as this source is enabled. Metadata checksums are looked up using the same file conventions as artifact checksums, with the metadata path composed from the origin repository key (for example g/a/v/maven-metadata-central.xml).

Specified by:

doGetTrustedMetadataChecksums in class FileTrustedChecksumsSourceSupport

doGetTrustedArtifactChecksumsWriter

protected TrustedChecksumsSource.Writer doGetTrustedArtifactChecksumsWriter(RepositorySystemSession session)

Description copied from class: FileTrustedChecksumsSourceSupport

Implementors may override this method and return TrustedChecksumsSource.Writer instance.
