slice

public void slice(long start,
                  long length)
           throws java.io.IOException

Description copied from interface: com.pt.io.RandomAccess

Restricts reads to a slice of file, from start to start + length - 1. While the slice is set, all file operations including RandomAccess.seek(long) and RandomAccess.getFilePointer() are relative to start, and RandomAccess.length() is set to the passed length. Subsequent slices are relative to the original file, not other slices. Remove the slice by invoking with slice(0, Long.MAX_VALUE).

Specified by:

slice in interface com.pt.io.RandomAccess

Throws:

java.io.IOException
