Allows for runtime registration of handler functions that override the default deprecation behavior. Deprecations are invoked by calls to @ember/debug/deprecate. The following example demonstrates its usage by registering a handler that throws an error if the message contains the word "should", otherwise defers to the default handler.

        
              import { registerDeprecationHandler } from '@ember/debug';

registerDeprecationHandler((message, options, next) => {
  if (message.indexOf('should') !== -1) {
    throw new Error(`Deprecation message with should: ${message}`);
  } else {
    // defer to whatever handler was registered before this one
    next(message, options);
  }
});

The handler function takes the following arguments:

message - The message received from the deprecation call.
options - An object passed in with the deprecation call containing additional information including:

id - An id of the deprecation in the form of package-name.specific-deprecation.
until - The Ember version number the feature and deprecation will be removed in.

next - A function that calls into the previously registered handler.
