This method may return different results depending on the value of $checkInstance.
- If $checkInstance is false (default), the method will return a value indicating whether the locator has the specified
component definition.
- If $checkInstance is true, the method will return a value indicating whether the locator has
instantiated the specified component.

| $id | string | component ID (e.g. `db`). |
| $checkInstance | boolean | whether the method should check if the component is shared and instantiated. |
| return | boolean | whether the locator has the specified component definition or has instantiated the component. |
