bbcursive is a library to make Java ByteBuffer work more terse and demand fewer casting expressions.

after years of working with bytebuffers with rewarding tradeoffs for ugly syntax I built this to simplify some common idioms repeated in many places.

example below: parsing http 1.1 chunked transefer-encoding involves decoding

[WS]<hex><CRLF><DATA><CRLF>

public ByteBuffer getNextChunk() throws BufferUnderflowException {
ByteBuffer payload = payload();
bb(payload, flip);
int needs;
ByteBuffer lenBuf;
try {

 lenBuf = bb(this.payload, mark, skipWs, slice, forceToEol, rtrim, flip);

 String lenString = str(lenBuf, post.rewind);
needs = Integer.parseInt(lenString, 0x10);
} catch (Exception e) {
payload.reset();
throw new BufferUnderflowException();
}
bb(this.payload, toEol);
if (needs != 0) {
ByteBuffer chunk = ByteBuffer.allocateDirect(needs);
cat(payload, chunk);
bb(payload, compact, debug);
return chunk;
}
return NIL;
}
