@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:29:55.199Z") @Stability(Stable) public abstract class Matcher extends software.amazon.jsii.JsiiObject
Represents a matcher that can perform special data matching capabilities between a given pattern and a target.

Example: 

 // Given a template -
 // {
 //   "Resources": {
 //     "MyBar": {
 //       "Type": "Foo::Bar",
 //       "Properties": {
 //         "Fred": ["Flob", "Cat"]
 //       }
 //     }
 //   }
 // }
 // The following will NOT throw an assertion error
 template.hasResourceProperties("Foo::Bar", Map.of(
         "Fred", Match.arrayWith(List.of("Flob"))));
 // The following will throw an assertion error
 template.hasResourceProperties("Foo::Bar", Match.objectLike(Map.of(
         "Fred", Match.arrayWith(List.of("Wobble")))));
