FileReadPlan

cc.otavia.core.channel.message.FileReadPlan

case class FileReadPlan(length: Int, position: Long) extends ReadPlan

Read file channel from position with length， See also FileChannel.

Value parameters

length: Length of bytes want to read. If length is -1, read until file end.
position: If position is -1, bytes are read starting at this channel's current file position, and then the file position is updated with the number of bytes actually read. If position is not -1, then read starting at the given file position rather than at the channel's current position. This method does not modify this channel's position. If the given position is greater than the file's current size then no bytes are read.

Guess the capacity for the next receive buffer size that is probably large enough to read all inbound data and small enough not to waste its space.

Notify the ReadPlan of the last read operation and its result.

actualBytesRead: The number of bytes from the previous read operation. This may be negative if a read error occurs.
attemptedBytesRead: The number of bytes the read operation did attempt to read.
numMessagesRead: The number of messages read.

Method that must be called once the read loop was completed.
