Method Detail

readAddress

public static Address readAddress(org.jboss.netty.buffer.ChannelBuffer buffer)
                           throws UnrecoverablePduException,
                                  RecoverablePduException

Read and create a new Address from a buffer. Checks if there is a minimum number of bytes readable from the buffer.

Parameters:

buffer -

Returns:

Throws:

UnrecoverablePduEncodingException

RecoverablePduEncodingException

UnrecoverablePduException

RecoverablePduException

writeAddress

public static void writeAddress(org.jboss.netty.buffer.ChannelBuffer buffer,
                Address value)
                         throws UnrecoverablePduException,
                                RecoverablePduException

Writes an address to a buffer. If the address is null, this method will safely write out the SmppConstants.EMPTY_ADDRESS instance.

Parameters:

buffer -

value -

Throws:

UnrecoverablePduEncodingException

RecoverablePduEncodingException

UnrecoverablePduException

RecoverablePduException

readTlv

public static Tlv readTlv(org.jboss.netty.buffer.ChannelBuffer buffer)
                   throws NotEnoughDataInBufferException

Reads a TLV from a buffer. This method is greedy and will read bytes even if it won't be able to successfully complete. It's assumed this method will only be called if its known ahead of time that all bytes will be available ahead of time.

Parameters:

buffer - The buffer to read from

Returns:

A new TLV instance

Throws:

NotEnoughDataInBufferException

writeTlv

public static void writeTlv(org.jboss.netty.buffer.ChannelBuffer buffer,
            Tlv tlv)
                     throws NotEnoughDataInBufferException

Throws:

NotEnoughDataInBufferException

writeNullTerminatedString

public static void writeNullTerminatedString(org.jboss.netty.buffer.ChannelBuffer buffer,
                             String value)
                                      throws UnrecoverablePduException

Writes a C-String (null terminated) to a buffer. If the String is null this method will only write out the NULL byte (0x00) to the buffer.

Parameters:

buffer -

value -

Throws:

UnsupportedEncodingException

UnrecoverablePduException

readNullTerminatedString

public static String readNullTerminatedString(org.jboss.netty.buffer.ChannelBuffer buffer)
                                       throws TerminatingNullByteNotFoundException

Reads a C-String (null terminated) from a buffer. This method will attempt to find the null byte and read all data up to and including the null byte. The returned String does not include the null byte. Will throw an exception if no null byte is found and it runs out of data in the buffer to read.

Parameters:

buffer -

Returns:

Throws:

TerminatingNullByteNotFoundException
