IcePatch2::FileServer
Overview
interface FileServer
The interface that provides access to files.
Operation Index
getFileInfoSeq — Return the IcePatch2::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
[ "nonmutating" ] IcePatch2::FileInfoSeq getFileInfoSeq(int partition) throws IcePatch2::PartitionOutOfRangeException
Return the IcePatch2::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 IcePatch2::FileInfo structures for files in the specified partition.
[ "nonmutating" ] IcePatch2::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.
[ "nonmutating" ] 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.
[ "amd", "nonmutating", "cpp:array" ] Ice::ByteSeq getFileCompressed(string path, int pos, int num) throws IcePatch2::FileAccessException
Read the specified file. If the read operation fails, the operation throws IcePatch2::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.
