Examples with SupportedAlgorithm gov.loc.repository.bagit.hash.SupportedAlgorithm used on opensource projects

Example 1 with SupportedAlgorithm

use of gov.loc.repository.bagit.hash.SupportedAlgorithm in project bagit-java by LibraryOfCongress.

the class BagVerifierTest method testVerificationExceptionIsThrownForNoSuchAlgorithmException.

@Test(expected = VerificationException.class)
public void testVerificationExceptionIsThrownForNoSuchAlgorithmException() throws Exception {
    Path unreadableFile = Paths.get(folder.newFile().toURI());
    Manifest manifest = new Manifest(new SupportedAlgorithm() {

        @Override
        public String getMessageDigestName() {
            return "FOO";
        }

        @Override
        public String getBagitName() {
            return "foo";
        }
    });
    manifest.getFileToChecksumMap().put(unreadableFile, "foo");
    sut.checkHashes(manifest);
}

Example 2 with SupportedAlgorithm

use of gov.loc.repository.bagit.hash.SupportedAlgorithm in project bagit-java by LibraryOfCongress.

the class ManifestReader method readManifest.

/**
 * Reads a manifest file and converts it to a {@link Manifest} object.
 *
 * @param nameMapping a map between BagIt algorithm names and {@link MessageDigest} names
 * @param manifestFile a specific manifest file
 * @param bagRootDir the root directory of the bag
 * @param charset the encoding to use when reading the manifest file
 * @return the converted manifest object from the file
 *
 * @throws IOException if there is a problem reading a file
 * @throws MaliciousPathException if there is path that is referenced in the manifest that is outside the bag root directory
 * @throws UnsupportedAlgorithmException if the manifest uses a algorithm that isn't supported
 * @throws InvalidBagitFileFormatException if the manifest is not formatted properly
