Detailed Description

template<typename V, typename A, typename Cond>
struct morph::forms::ReadonlyWhen< V, A, Cond >

Presentation rule: the listed field is editable only while Cond does not hold (the field is read-only while when holds). Never gates allRulesSatisfied, exactly like VisibleWhen.

Template Parameters

V	Field member type.
A	Action type the field belongs to.
Cond	Condition node type.

Member Function Documentation

test()

template<typename V, typename A, typename Cond>

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

inlinenodiscardconstexprnoexcept

Always true: presentation rules never gate submission. A renderer inspects when directly (not this method) to decide the field's editability.

Parameters

action

Unused (kept for interface uniformity with every other rule node).

Returns

true, unconditionally.

Definition at line 1707 of file forms.hpp.

emitNode()

template<typename V, typename A, typename Cond>

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

inlinenodiscard

Emits this rule's x-rules JSON node.

Returns

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