Method Detail

getMagicPattern

byte[] getMagicPattern()
                       throws java.io.IOException

Description copied from interface: BlockRecord

Returns the Magic number or pattern that is used to uniquely identify the file type of the capture file. The magic number is not normalized so the pattern may be returned differently on big and small endian machines.

Specified by:

getMagicPattern in interface BlockRecord

Returns:

pattern that is used to identify the file type

Throws:

java.io.IOException - any IO errors
