Interface ErrorMessageOverlayConfig

Allows overwriting of the error messages displayed in the overlay for customization and localization. This is either a function that receives any ErrorEvent as parameter and translates error messages, or a map of error codes that overwrites specific error messages with a plain string or a function that receives the ErrorEvent as parameter and returns a customized string. The translation functions can be used to extract data (e.g. parameters) from the original error message.

Example 1 (catch-all translation function): errorMessageOverlayConfig = { messages: function(error) { switch (error.code) { // Overwrite error 1000 'Unknown error' case 1000: return 'Houston, we have a problem'

  // Transform error 1201 'The downloaded manifest is invalid' to uppercase
  case 1201:
    var description = ErrorUtils.defaultErrorMessages[error.code];
    return description.toUpperCase();

  // Customize error 1207 'The manifest could not be loaded'
  case 1207:
    var statusCode = error.data.statusCode;
    return 'Manifest loading failed with HTTP error ' + statusCode;
}
// Return unmodified error message for all other errors
return error.message;

} };

Example 2 (translating specific errors): errorMessageOverlayConfig = { messages: { // Overwrite error 1000 'Unknown error' 1000: 'Houston, we have a problem',

// Transform error 1201 'Unsupported manifest format' to uppercase
1201: function(error) {
  var description = ErrorUtils.defaultErrorMessages[error.code];
  return description.toUpperCase();
},

// Customize error 1207 'The manifest could not be loaded'
1207: function(error) {
  var statusCode = error.data.statusCode;
  return 'Manifest loading failed with HTTP error ' + statusCode;
}

} };
