getNextArEntry

public ArArchiveEntry getNextArEntry()
                              throws IOException

Returns the next AR entry in this stream.

Returns:

the next AR entry.

Throws:

IOException - if the entry could not be read

getNextEntry

public ArchiveEntry getNextEntry()
                          throws IOException

Description copied from class: ArchiveInputStream

Returns the next Archive Entry in this Stream.

Specified by:

getNextEntry in class ArchiveInputStream

Returns:

the next entry, or null if there are no more entries

Throws:

IOException - if the next entry could not be read

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class InputStream

Throws:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Overrides:

read in class InputStream

Throws:

IOException

matches

public static boolean matches(byte[] signature,
                              int length)

Checks if the signature matches ASCII "!<arch>" followed by a single LF control character

Parameters:

signature - the bytes to check

length - the number of bytes to check

Returns:

true, if this stream is an Ar archive stream, false otherwise
