Function collectDirectiveIO

collectDirectiveIO(
cls: ClassDeclaration,
componentDecorators?: readonly string[],
): DirectiveIO
Lists the public inputs and outputs of a component or directive class and its base classes, as a parent template binds them. Members of the class win over same-name members of a base class.
Parameters
- cls: ClassDeclaration
  Component or directive class.
- OptionalcomponentDecorators: readonly string[]
  Project component decorators in addition to Component (parser.componentDecorators) whose metadata can declare inputs / outputs.
Returns DirectiveIO
Remarks
Sources:
- @Input() / @Output() on properties and accessors, with a string alias or { alias, required }
- signal APIs: input(), input.required(), model() (input plus <name>Change output), output(), outputFromObservable(), with an { alias } option
- inputs: [...] / outputs: [...] in the decorator metadata ('prop', 'prop: alias', { name, alias, required })
Example
```
collectDirectiveIO(itemClass);
// { inputs: [{ name: 'item', property: 'item', required: true, source: 'signal' }],
//   outputs: [{ name: 'formError', property: 'formError', source: 'decorator' }] }
```
