For creating writers/readers for buffer messages
XALBufferMessages was created to offer a fast way to create functions that write/read from/to messages with a fixed number of variables. The creator of writer and reader supports adding an offset for adding custom data to the buffer.
To create a writer and reader function for message composed of a signed, big-endian 32-bit integer and a string you can write:
import { createMessageReader, createMessageWriter, VariableType } from '@softprovider/xalbuffermessages';
const MessageVariables = [ VariableType.INT_32_BE, VariableType.STRING ];
const writer = createMessageWriter(MessageVariables);
const reader = createMessageReader(MessageVariables);And now that we have our writer and reader messages we just need to call them:
const buffer = writer(0, 0, 32, "radom string"); // <= Buffer("")
const result = reader(0, 0, buffer); // <= { data: [32, "random string"], nextByte: 0 }
