Returns a composed constraint that represents a logical AND of this constraint and another.
If the composed constraint would be unsatisfiable, an Error
is thrown.

Require a value at a specific position in the JSON object.
The pointer is a

syntax reference locating the value in the JSON object. If
the pointer parameter cannot be parsed as a JSON pointer an
Error is thrown.
The function returns a new PartialJSON object. The original object remains unmodified.

Require a specific position in the JSON object to be empty.
The pointer is a
JSON Pointer syntax
reference that should have no value in the JSON object. If the
pointer parameter cannot be parsed as a JSON pointer an
Error is thrown.
The function returns a new PartialJSON object. The original object remains unmodified.

A constraint requiring the current value of the JSON topic to match the partially described value.
The code:
const factory = diffusion.updateConstraints(); const constraint = factory.jsonValue().with('/id', idValue).without('/cancellation');creates a constraint for a JSON object with a specific ID value and no value for a 'cancellation' property.
