Detailed Description
HFFileByteSlice is a subclass of HFByteSlice that represents a portion of data from a file. The file is specified as an HFFileReference; since the HFFileReference encapsulates the file descriptor, multiple HFFileByteSlices may all reference the same file without risking overrunning the limit on open files.Member Function Documentation
