toCommandMessage
Converts any object to a CommandMessage using reflection and metadata.
This extension function analyzes the command object's class to extract metadata and construct a properly configured CommandMessage. It uses command metadata to determine aggregate targeting, property getters, and command characteristics.
Return
a properly configured CommandMessage
Parameters
unique identifier for the command message (auto-generated if not provided)
request identifier for tracking (defaults to id)
target aggregate instance ID (optional, extracted from command if available)
tenant identifier (optional, extracted from command if available)
owner identifier (optional, extracted from command if available)
space identifier (optional); ignored, in favour of the default space, when the target aggregate is known here and is not spaced (@Spaced)
expected aggregate version (optional, extracted from command if available)
named aggregate information (optional, extracted from command if available)
message headers (default empty)
creation timestamp (default current time)
upstream domain event (optional)
whether owner ID should match aggregate ID
propagates upstream's context into header (default: MessagePropagators.DEFAULT)
Type Parameters
the type of the command

Throws
if no named aggregate can be determined

Type Parameters
the type of the command body
