Detailed Description

template<typename V, typename A>
struct morph::forms::Engaged< V, A >

Condition: field is engaged (has a value). One of the closed condition kinds a requiredWhen / visibleWhen / readonlyWhen rule's when clause accepts.

Template Parameters

V	Field member type (must satisfy EngageableField).
A	Action type the field belongs to.

test()

template<typename V, typename A>

bool morph::forms::Engaged< V, A >::test ( const A & action ) const

inlinenodiscardconstexprnoexcept

Evaluates the condition against action.

Parameters

action

The action snapshot to inspect.

Returns

true when the field is engaged.

Definition at line 932 of file forms.hpp.

emitNode()

template<typename V, typename A>

glz::generic_u64 morph::forms::Engaged< V, A >::emitNode ( ) const

inlinenodiscard

Emits this condition's x-rules JSON node.

Returns

{"kind":"engaged","fields":["<wire name>"]}.

kind

template<typename V, typename A>
