capabilities property
DocumentCapabilities
get
capabilities
What this build tells the server it can read.
Defaults to CRDTDocument.describeBuildCapabilities, sent as
incomplete: an app usually opens a handler after connecting, so a kind
it does not name is passed over rather than refused. One passed at
construction is sent as complete, and a kind left out refuses the client.
Either way, a kind that is named is checked in full: a missing operation kind, or a snapshot blob of another layout, refuses the client.
Implementation
DocumentCapabilities get capabilities =>
_declaredCapabilities ?? document.describeBuildCapabilities();
