Method Detail

open

public void open()
          throws ReaderException

Description copied from interface: SerialTransport

Causes the communication interface to be opened but does not transmit any serial-layer data. This should perform actions such as opening a serial port device or establishing a network connection within a wrapper protocol.

Specified by:

open in interface SerialTransport

Throws:

ReaderException

sendBytes

public void sendBytes(int length,
                      byte[] message,
                      int offset,
                      int timeoutMs)
               throws ReaderException

Description copied from interface: SerialTransport

Send bytes down the serial transport layer. No interpretation or modification occurs.

Specified by:

sendBytes in interface SerialTransport

Parameters:

length - number of bytes to send

message - array containing the bytes to be sent

offset - position in array to send from

timeoutMs - The duration to wait for the operation to complete.

Throws:

ReaderException

receiveBytes

public byte[] receiveBytes(int length,
                           byte[] messageSpace,
                           int offset,
                           int timeoutMillis)
                    throws ReaderException

Description copied from interface: SerialTransport

Receive a number of bytes on the serial transport.

Specified by:

receiveBytes in interface SerialTransport

Parameters:

length - number of bytes to receive

messageSpace - byte array to store the message in, or null to have one allocated

offset - location in messageSpace to store bytes

timeoutMillis - maximum duration to wait for a message

Returns:

the byte array with the number of bytes added

Throws:

ReaderException

performRead

public int performRead(byte[] mReadBuffer,
                       int length,
                       int offset,
                       int timeoutMillis)
                throws ReaderCommException

Throws:

ReaderCommException

copyRequestedData

public byte[] copyRequestedData(int length,
                                byte[] messageSpace,
                                int offset)

checkForCorruptedData

public byte[] checkForCorruptedData(int length,
                                    int offset,
                                    byte[] messageSpace)

getBaudRate

public int getBaudRate()
                throws ReaderException

Description copied from interface: SerialTransport

Get the current baud rate of the communication channel.

Specified by:

getBaudRate in interface SerialTransport

Returns:

the baud rate

Throws:

ReaderException

setBaudRate

public void setBaudRate(int baudRate)
                 throws ReaderException

Description copied from interface: SerialTransport

Set the current baud rate of the communication channel.

Specified by:

setBaudRate in interface SerialTransport

Parameters:

baudRate - the baud rate to set

Throws:

ReaderException

public void flush()
           throws ReaderException

Description copied from interface: SerialTransport

Take any actions necessary (possibly none) to remove unsent data from the output path.

Specified by:
