Design Principles

• The Java API largely consists of interfaces with factory methods named of or ofXxx.
• Nullable types are annotated with org.jspecify.Nullable. Types not annotated with Nullable are implicitly org.jspecify.NonNull. Non-nullness of method arguments is not enforced with runtime checks.
• MxPack throws the exception types listed in MxPackException.
• MxPack embraces Java NIO. For best performance, use MessageSources and MessageSinks backed by java.nio.channels.Channels. Byte buffers are represented as java.nio.ByteBuffer and LeasedByteBuffer. If frequent buffer allocations are a concern, share a single pooled BufferAllocator between message sources and sinks.
