readblock and readnextheaderblock are the methods that users of this class should use to read header blocks from the tar file . readnextheaderblock continues working through the tar file from the current point until it finds a block with a non-0 first byte . concode_field_sep int DEFAULT_BLOCKS_PER_RECORD concode_elem_sep int DEFAULT_COMPRESSION concode_elem_sep byte[] readBuffer concode_elem_sep long bytesRead concode_elem_sep int readBufferBlocks concode_elem_sep int NO_COMPRESSION concode_elem_sep InputStream readStream concode_elem_sep int GZIP_COMPRESSION concode_elem_sep int compressionType concode_field_sep int getReadBufferBlocks concode_elem_sep void readBlock concode_elem_sep void readBlocks concode_elem_sep void readCompressedBlocks concode_elem_sep void close
