Constructor Detail

NAVXFile

public NAVXFile(File file)
         throws IOException

Create a NAVXFile from the specified file.

Parameters:

file - the file to open

Throws:

IOException - if an I/O error occurs

Parameters:

channel - the channel to read the file from

Throws:

IOException - if an I/O error occurs

Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

computeDigest

public byte[] computeDigest(net.jsign.DigestAlgorithm digestAlgorithm)
                     throws IOException

Description copied from interface: Signable

Computes the digest of the file.

Specified by:

computeDigest in interface Signable
