Examples of java.nio.channels.FileChannel.transferFrom()

java.nio.channels.FileChannel.transferFrom()
Transfers bytes into this channel's file from the given readable byte channel. It may be very efficient. By invoking this methid, it will read form the source channel and write into the file channel. Note: no guarantee whether all bytes may be transferred. And it does not modify the position of the channel. @param src the source channel to read @param position the non-negative position to begin @param count the non-negative bytes to be transferred @return the number of bytes that are transferred. @throws IllegalArgumentException If the parameters are not correct @throws NonReadableChannelException If the source channel is not readable @throws NonWritableChannelException If this channel is not writable @throws ClosedChannelException If either channel has already been closed @throws AsynchronousCloseException If either channel is closed by other threads during this operation @throws ClosedByInterruptException If the thread is interrupted during this operation @throws IOException If any I/O error occurs
