org.apache.cxf.ws.mex.model._2004_09.Metadata

SimpleSeekableFormat supports seek based on compressed byte offsets as well as uncompressed byte offsets. File Format Description: 0. Definition * Metadata block: a fixed size block of 1024 bytes storing metadata of the file. * Data block: a fixed size block of 1023K bytes storing actual data. * Data segment: a variable-length segment of bytes storing a logical data unit that needs to be processed together. 1. File Format Layout Each 1K bytes at the beginning of x MB is a metadata block. The rest of 1023K bytes are data blocks. 2. Metadata block (1024 bytes): Each metadata block looks like this: 32 bytes: "SSF_Magic_C17e5C697a00bB1A859aD\n" 4 bytes: version number, now is 1. 16 bytes: 8-byte of uncompressed data stream offset + 8-byte of compressed data stream offset 3. Data block (1023 * 1024 bytes): All data blocks should be concatenated to be a stream. The stream consists of consecutive data segments, back by back. 4. Data segment: Each data segment looks like this: 4 bytes: length (implies that a single data segment cannot be longer than 4GB). It does not include the length field itself, but includes all following fields like codec name and crc32 checksum. 2 bytes: byte length of compression codec class name. Or 0 for uncompressed. x-bytes: UTF-8 encoded compression codec class name. (Only when x = 0) 8 bytes: crc32 checksum of the data following. (length - 2 - x - (x==0?8:0) ) bytes: actual data This class encapsulates all underlying logics of the SeekableFileFormat. NOTE: Requirement on the CompressionCodec InputStream: available() should only return 0 when EOF. Otherwise SeekableFileInputStream.available() will break.
