Detailed Description

Schema for a single input or output port of an action.

Describes the port's name and payload type, whether it is required and unary (a single value rather than a stream), an optional description, and input autofills. Before applying autofills the runtime requires that input to be writable and empty; existing data causes the action to fail rather than overriding a receiver-owned default.

autofills

std::vector<std::optional<data::NodeFragment> > a11::actions::ActionPortSchema::autofills

Input-default fragments; an autofilled input must otherwise be empty.

description

std::string a11::actions::ActionPortSchema::description

Human-readable description.

name

std::string a11::actions::ActionPortSchema::name

Port name (unique within its direction).

required

bool a11::actions::ActionPortSchema::required = false

Whether the port must be supplied.

type

std::string a11::actions::ActionPortSchema::type

Payload type name.

typeinfo

std::shared_ptr<void> a11::actions::ActionPortSchema::typeinfo

Opaque, owning language-binding type handle (e.g.

a Python type object). The a11::actions layer stays language-agnostic: it only holds the handle and never dereferences it. Ownership is real – the binding that populates it installs a custom deleter (which reacquires its runtime's lock as needed), so the referent is kept alive for exactly as long as any copy of this schema, instead of being a borrowed pointer that can dangle once the caller drops its own reference. Empty when the port has no bound type.

unary

bool a11::actions::ActionPortSchema::unary = false

Whether the port carries a single value.
