public ByteBufferBytes slice()
BytesCommonThe content of the new bytes will start at this bytes' current position. Changes to this bytes' content will be visible in the new bytes, and vice versa; the two bytes' position and limit values will be independent.
The new bytes' position will be zero, its capacity and its limit will be the number of bytes remaining in this bytes.
slice() is equivalent of slice(0, remaining()).

BytesCommonThe content of the new bytes will start at this bytes' current
BytesCommon.position()+ offset. Changes to this bytes' content
will be visible in the new bytes, and vice versa; the two bytes'
position and limit values will be independent.
The new bytes' position will be zero, its capacity and its limit
will be equal to length.
offset can be negative (if current bytes' position is positive)
and length can run out of current bytes' limit, the restriction
is that new bytes' should be within this bytes' absolute bounds.

If this BytesStore is Bytes itself rather than natural
BytesStore object, this method will offset the new bytes from the
bytes' start, not from bytes' position like
BytesCommon.slice(long, long).
offset should be non-negative, length should be positive,
offset + length should be less or equal to size.

RandomDataInputReads len bytes from an input stream.
This method blocks until one of the following conditions occurs:
len bytes of input data are available, in which case a normal return is made.EOFException is thrown.IOException other than EOFException is thrown.
If bytes is null, a NullPointerException is thrown. If off is
negative, or len is negative, or off+len is greater than the length of the array
bytes, then an IndexOutOfBoundsException is thrown. If len is zero, then no
bytes are read. Otherwise, the first byte read is stored into element bytes[off], the next one into
bytes[off+1], and so on. The number of bytes read is, at most, equal to len.

RandomDataOutputfloat value, which is comprised of four bytes, to the output stream. It does this as if it
first converts this float value to an int in exactly the manner of the
Float.floatToIntBits method and then writes the int value in exactly the manner of the
writeInt method. The bytes written by this method may be read by the readFloat method
of interface DataInput, which will then return a float equal to v.writeFloat in interface DataOutputwriteFloat in interface RandomDataOutputv - the float value to be written.public void writeFloat(long offset,
