ImportObjectJSON

Object model, document editing

Description

Parses and validates a versioned object graph before cloning its values into the current document. By default, listed objects are created or updated and a supplied trailer is applied while unlisted objects remain. Option 4 additionally removes unlisted indirect objects, enabling exact graph replacement. Type mismatches, duplicate object numbers, malformed hexadecimal or Base64 data, unavailable stream data, excess nesting, and unsupported schema versions are rejected before normal updates begin
