Method Detail

readCommand

String readCommand()
            throws IOException

Reads a command.

Returns:

the command name.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readString

String readString()
           throws IOException

Reads a string parameter.

Returns:

the read string.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readLong

long readLong()
       throws IOException

Reads a long parameter.

Returns:

the read long.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readInt

int readInt()
     throws IOException

Reads an integer parameter.

Returns:

the read integer.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readFloat

float readFloat()
         throws IOException

Reads a float parameter.

Returns:

the read float.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readDouble

double readDouble()
           throws IOException

Reads a double parameter.

Returns:

the read double.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readBoolean

boolean readBoolean()
             throws IOException

Reads a boolean parameter.

Returns:

the read boolean.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readByteArray

byte[] readByteArray()
              throws IOException

Reads a byte array parameter.

Returns:

the read byte array.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readInputStream

InputStream readInputStream()
                     throws IOException

Reads an input stream.

The returned input stream must be fully read before returning the method.

Returns:

an inputStream.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

readObject

Object readObject()
           throws IOException

Reads a parameter, whatever it's type. Note that if the parameter is a byte array, it will be returned as an InputStream that must be completely consumed before reading the next parameter.

Returns:

an object reflecting the read parameter.

Throws:

IOException - the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.

skipParameters

void skipParameters()
             throws IOException

Skips the parameters of a command and get ready to read the following command.

Throws:

IOException
