SendObject

SendObject is a general term for a programming facility that transmits an object from one execution context to another. It typically involves serializing the object's state and transporting it across a channel, such as a network or inter-process communication link, so the recipient can reconstruct or use it.

In software libraries and frameworks, SendObject may be a named function or operation designed to encapsulate the steps of preparation, transmission, and optional acknowledgement. The exact semantics vary by language and platform, but common goals include correctness, portability, and efficiency in object transfer.

Serialization is a central aspect. Objects are converted to a portable representation (e.g., JSON, XML, or a binary format) before sending. The receiver then deserializes to recreate the object. Some implementations preserve object identity and references; others only copy data fields, limiting compatibility.

Transport layers differ. SendObject can use HTTP(S), WebSocket, message queues (AMQP, MQTT), or direct sockets. The choice affects latency, reliability, and ordering guarantees. Some systems implement acknowledgments or retries to improve delivery assurance.

Security and robustness are important considerations. Transmission may require authentication, encryption, and integrity checks. Versioning and schema evolution pose challenges when the sender and receiver implement different object definitions, potentially requiring adapters or compatibility layers.
