Method Detail

newChecksumPolicy

ChecksumPolicy newChecksumPolicy(RepositorySystemSession session,
                                 RemoteRepository repository,
                                 TransferResource resource,
                                 String policy)

Retrieves the checksum policy with the specified identifier for use on the given remote resource.

Parameters:

session - The repository system session during which the request is made, must not be null.

repository - The repository hosting the resource being transferred, must not be null.

resource - The transfer resource on which the policy will be applied, must not be null.

policy - The identifier of the policy to apply, must not be null.

Returns:

The policy to apply or null if checksums should be ignored.

getEffectiveChecksumPolicy

String getEffectiveChecksumPolicy(RepositorySystemSession session,
                                  String policy1,
                                  String policy2)

Returns the least strict policy. A checksum policy is said to be less strict than another policy if it would accept a downloaded resource in all cases where the other policy would reject the resource.

Parameters:

session - The repository system session during which the request is made, must not be null.

policy1 - A policy to compare, must not be null.

policy2 - A policy to compare, must not be null.

Returns:

The least strict policy among the two input policies.
