Method Detail

loadBuffer

public byte[] loadBuffer(long position,
                         int size)
                  throws java.io.IOException

Description copied from class: BinaryLoader

Loads the contents of the memory-mapped file starting at the given position and for the given size, into a byte buffer. This method is implemented because MappedByteBuffer.load() does not work properly.

Overrides:

loadBuffer in class BinaryLoader

Parameters:

position - the starting position in the file

size - the number of bytes to load

Returns:

the loaded ByteBuffer

Throws:

java.io.IOException - if IO went wrong
