How to use the @xviz/parser.XVIZObject.get function in @xviz/parser

function getProperty(context, propertyName, f = EMPTY_OBJECT) {
  let objectState = f;

  // Handle XVIZ v1 color override where our semantic color mapping
  // differs from current OCS colors.  In XVIZ v2 we should be aligned.
  if (context.useSemanticColor) {
    switch (propertyName) {
      case 'stroke_color':
      case 'fill_color':
        objectState = XVIZObject.get(f.id) || f;
        break;

      default:
      // ignore
    }
  }

  // Handle XVIZ v1 style property name mismatches and
  // setup validation function based on property name.
  let altPropertyName = null;

  switch (propertyName) {
    case 'stroke_color':
    case 'fill_color':
      altPropertyName = 'color';
      break;

export function setObjectState(objectStates, {stateName, id, value}) {
  const state = {...objectStates[stateName]};

  const xvizObject = XVIZObject.get(id);
  if (xvizObject) {
    xvizObject._setState(stateName, value);
  }

  if (value) {
    state[id] = value;
  } else {
    delete state[id];
  }

  return {
    ...objectStates,
    [stateName]: state
  };
}
