Cornerstone getMetaData function

[norman-ma]

This is the function which gets the metaData. When invoked it iterates through the list of providers, ordered by their priority and returns the result from the first one to return a value based on the type parameter.

function getMetaData (type, imageId) {
  // Invoke each provider in priority order until one returns something
  for (let i = 0; i < providers.length; i++) {
    const result = providers[i].provider(type, imageId);

    if (result !== undefined) {
      return result;
    }
  }
}
