registerDeprecationHandler (handler) publicstatic
Allows for runtime registration of handler functions that override the default deprecation behavior. Deprecations are invoked by calls to Ember.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.
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 ofpackage-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.
Parameters:
-
