copyTo
Copy bytes from this buffer's subrange, starting at startIndex and ending at endIndex, to out. This method does not consume data from the buffer.
Parameters
out
the destination to copy data into.
startIndex
the index (inclusive) of the first byte to copy, 0 by default.
endIndex
the index (exclusive) of the last byte to copy, buffer.size by default.
Throws
when startIndex or endIndex is out of this buffer bounds ([0..buffer.size)).
when startIndex > endIndex.
