      • newChecksumPolicy

        ChecksumPolicy newChecksumPolicy​(RepositorySystemSession session,
                                 RemoteRepository repository,
                                 TransferResource resource,
                                 java.lang.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

        java.lang.String getEffectiveChecksumPolicy​(RepositorySystemSession session,
                                            java.lang.String policy1,
                                            java.lang.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.
