IcePatch2::FileServer
Overview
interface FileServer
The interface that provides access to files.
Operation Index
- getFileInfoSeq
- Return the FileInfoSeq for the specified partition.
- getChecksumSeq
- Return the checksums for all partitions.
- getChecksum
- Return the master checksum for all partitions.
- getFileCompressed
- Read the specified file.
Operations
FileInfoSeq getFileInfoSeq(int partition) throws PartitionOutOfRangeException
Return the FileInfoSeq for the specified partition. If the partion number is out of range, the operation throws PartitionOutOfRangException.
Parameters
- partition
- The partition number in the range 0-255.
Return Value
A sequence containing the FileInfo structures for files in the specified partition.
ByteSeqSeq getChecksumSeq()
Return the checksums for all partitions.
Return Value
A sequence containing 256 checksums. Partitions with a checksum that differs from the previous checksum for the same partition contain updated files. Partitions with a checksum that is identical to the previous checksum do not contain updated files.
::Ice::ByteSeq getChecksum()
Return the master checksum for all partitions. If this checksum is the same as for a previous run, the entire file set is up-to-date.
Return Value
The master checksum for the file set.
::Ice::ByteSeq getFileCompressed(string path, int pos, int num) throws FileAccessException
Read the specified file. If the read operation fails, the operation throws FileAccessException. This operation may only return fewer bytes than requested in case there was an end-of-file condition.
Parameters
- path
- The pathname (relative to the data directory) for the file to be read.
- pos
- The file offset at which to begin reading.
- num
- The number of bytes to be read.
Return Value
A sequence containing the compressed file contents.
