### `before_category_group_insert($category_group, $values)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
Returns | `NULL` | void

Called before the category group object is inserted. Changes made to the object will be saved automatically.

How it’s called:

    ee()->extensions->call('before_category_group_insert', $this, $this->getValues());

### `after_category_group_insert($category_group, $values)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
Returns | `NULL` | void

Called after the category group object is inserted. Changes made to the object object will not be saved automatically. Saving the object may trigger the save and update hooks.

How it’s called:

    ee()->extensions->call('after_category_group_insert', $this, $this->getValues());

### `before_category_group_update($category_group, $values, $modified)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
$modified | `Array` | An array of all the old values that were changed
Returns | `NULL` | void

Called before the category group object is updated. Changes made to the object will be saved automatically.

How it’s called:

    ee()->extensions->call('before_category_group_update', $this, $this->getValues(), $modified);

### `after_category_group_update($category_group, $values, $modified)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
$modified | `Array` | An array of all the old values that were changed
Returns | `NULL` | void

Called after the category group object is updated. Changes made to the object will not be saved automatically. Calling save may fire additional hooks.

How it’s called:

    ee()->extensions->call('after_category_group_update', $this, $this->getValues(), $modified);

### `before_category_group_save($category_group, $values)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
Returns | `NULL` | void

Called before the category group object is inserted or updated. Changes made to the object will be saved automatically.

How it’s called:

    ee()->extensions->call('before_category_group_save', $this, $this->getValues());

### `after_category_group_save($category_group, $values)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
Returns | `NULL` | void

Called after the category group object is inserted or updated. Changes made to the object will not be saved automatically. Calling save may fire additional hooks.

### `before_category_group_delete($category_group, $values)`

Parameter | Type | Description
--- | --- | ---
$category_group | `Object` | Current CategoryGroup model object
$values | `Array` | The CategoryGroup model object data as an array
Returns | `NULL` | void

Called before the category group object is deleted. If you are conditionally deleting one of your own models, please consider creating an inverse relationship instead. This will provide better performance and strictly enforce data consistency.

How it’s called:

    ee()->extensions->call('before_category_group_delete', $this, $this->getValues());

### `after_category_group_delete($category_group, $values)`

Parameter | Type | Description
