package com.babelqueue

BabelQueue — Polyglot Queues, Simplified.

The framework-agnostic Java core: the canonical wire-envelope codec (EnvelopeCodec), contracts (PolyglotMessage, HasTraceId) and dead-letter helpers (DeadLetters). It lets a Java service exchange queue messages with the PHP/Laravel, Python, Go and Node SDKs over one strict JSON format — with zero dependencies (pure JDK, including its own minimal JSON codec).

Package	Description

Class	Description
BabelQueueException	Base unchecked exception for all BabelQueue failures.
DeadLetter	The additive block appended to an Envelope when a message is dead-lettered.
DeadLetters	Builds the additive dead_letter block for an Envelope.
Envelope	The canonical BabelQueue wire message: a strict, language-neutral JSON shape ({job, trace_id, data, meta, attempts}) that every SDK produces and consumes identically — no language-specific serialization on the wire.
EnvelopeCodec	Builds, encodes and decodes the canonical BabelQueue envelope — the single Java implementation of the wire format.
HasTraceId	Optionally implemented alongside PolyglotMessage to continue an existing distributed trace instead of minting a fresh one.
Meta	The immutable per-message metadata block of a Envelope.
PolyglotMessage	A message that can be produced as a polyglot envelope.
Redrive	DLQ redrive tooling — safe replay off the dead-letter queue (ADR-0026).
Redrive.Item	What happened to one message during a Redrive.redrive(com.babelqueue.Redrive.Transport, java.lang.String, com.babelqueue.Redrive.Options) run.
Redrive.Options	Options for a Redrive.redrive(com.babelqueue.Redrive.Transport, java.lang.String, com.babelqueue.Redrive.Options) run; immutable, built with the fluent withers from Redrive.Options.all().
Redrive.Reserved	A reserved DLQ message: its raw body plus a transport-specific handle used to ack it.
Redrive.Result	Summary of a Redrive.redrive(com.babelqueue.Redrive.Transport, java.lang.String, com.babelqueue.Redrive.Options) run.
Redrive.Transport	The minimal transport surface Redrive.redrive(com.babelqueue.Redrive.Transport, java.lang.String, com.babelqueue.Redrive.Options) needs, implemented over any broker.
UnknownUrnException	Raised when no handler is mapped for a message URN.
UnknownUrnStrategy	What a consumer does with a message whose URN has no registered handler.
