DelayedMutate¶

Overview¶

A mixin that delays the mutation of a certain set of mutation keys until AFTER the super() call has fully finished. This can be wrapped around a type where a mutate( { someKey: ... } ) would cause an error in the super(), and we want to postpone that until after construction. e.g.:

const SomeNode = DelayedMutate( 'SomeNode', [ 'someOption' ], class extends SuperNode { constructor( options ) { super( options );

this.someOptionProperty = new Property( something );

}

set someOption( value: Something ) { this.someOptionProperty.value = value; }

get someOption(): Something { return this.someOptionProperty.value; } } );

If this was NOT done, the following would error out:

new SomeNode( { someOption: something } )
