新的Java花括号

Question

我对Java比较陌生，偶然发现了用于CA证书绕过的代码片段。在为TrustManager []和X509TrustManager（）更新之后，我无法理解花括号。有人能解开一些光吗？谢谢。

TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }
    };
