Example 1 with NamespaceIsolationPolicy

    nsPolicyData.auto_failover_policy.parameters = new HashMap<String, String>();
    nsPolicyData.auto_failover_policy.parameters.put("min_limit", "1");
    nsPolicyData.auto_failover_policy.parameters.put("usage_threshold", "100");
    policies.setPolicy("otherPolicy", nsPolicyData);
    byte[] morePolicyJson = jsonMapperForWriter.writeValueAsBytes(policies.getPolicies());
    ObjectMapper jsonParser = ObjectMapperFactory.create();
    Map<String, NamespaceIsolationData> policiesMap = jsonParser.readValue(morePolicyJson, new TypeReference<Map<String, NamespaceIsolationData>>() {
    });
    assertEquals(policiesMap.size(), 2);
}

}

Example 3 with NamespaceIsolationPolicy
