expression\n * bound to the trigger changes.\n *\n * @param name An identifying string.\n * @param definitions An animation definition object, containing an array of\n * [`state()`](api/animations/state) and `transition()` declarations.\n *\n * @return An object that encapsulates the trigger data.\n *\n * @usageNotes\n * Define an animation trigger in the `animations` section of `@Component` metadata.\n * In the template, reference the trigger by name and bind it to a trigger expression that\n * evaluates to a defined animation state, using the following format:\n *\n * `[@triggerName]=\"expression\"`\n *\n * Animation trigger bindings convert all values to strings, and then match the\n * previous and current values against any linked transitions.\n * Booleans can be specified as `1` or `true` and `0` or `false`.\n *\n * ### Usage Example\n *\n * The following example creates an animation trigger reference based on the provided\n * name value.\n * The provided animation value is expected to be an array consisting of state and\n * transition declarations.\n *\n * ```typescript\n * @Component({\n * selector: \"my-component\",\n * templateUrl: \"my-component-tpl.html\",\n * animations: [\n * trigger(\"myAnimationTrigger\", [\n * state(...),\n * state(...),\n * transition(...),\n * transition(...)\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"something\";\n * }\n * ```\n *\n * The template associated with this component makes use of the defined trigger\n * by binding to an element within its template code.\n *\n * ```html\n * \n * http://example.com#/foo,\n * and `PathLocationStrategy` produces\n * http://example.com/foo as an equivalent URL.\n *\n * See these two classes for more.\n *\n * @publicApi\n
