Class RepositoryLayout.Checksum

java.lang.Object

org.eclipse.aether.spi.connector.layout.RepositoryLayout.Checksum

Enclosing interface:

RepositoryLayout

public static final class RepositoryLayout.Checksum
extends java.lang.Object

A descriptor for a checksum file. This descriptor simply associates the location of a checksum file with the underlying algorithm used to calculate/verify it. Checksum algorithms are denoted by names as used with MessageDigest.getInstance(String), e.g. "SHA-1" or "MD5".

Constructor Detail

Checksum

public Checksum(java.lang.String algorithm,
                java.net.URI location)

Creates a new checksum file descriptor with the specified algorithm and location. The method forLocation(URI, String) is usually more convenient though.

Parameters:

algorithm - The algorithm used to calculate the checksum, must not be null.

location - The relative URI to the checksum file within a repository, must not be null.

Method Detail

forLocation

public static RepositoryLayout.Checksum forLocation(java.net.URI location,
                                                    java.lang.String algorithm)

Creates a checksum file descriptor for the specified artifact/metadata location and algorithm. The location of the checksum file itself is derived from the supplied resource URI by appending the file extension corresponding to the algorithm. The file extension in turn is derived from the algorithm name by stripping out any hyphen ('-') characters and lower-casing the name, e.g. "SHA-1" is mapped to ".sha1".

Parameters:

location - The relative URI to the artifact/metadata whose checksum file is being obtained, must not be null and must not have a query or fragment part.

algorithm - The algorithm used to calculate the checksum, must not be null.

Returns:

The checksum file descriptor, never null.

verify

private static void verify(java.lang.String algorithm,
                           java.net.URI location)

getAlgorithm

public java.lang.String getAlgorithm()

Gets the name of the algorithm that is used to calculate the checksum.

Returns:

The algorithm name, never null.

MessageDigest.getInstance(String)

getLocation

public java.net.URI getLocation()

Gets the location of the checksum file with a remote repository. The URI is relative to the root directory of the repository.

Returns:

The relative URI to the checksum file, never null.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
