Examples with ClientMetadataService org.apache.geode.cache.client.internal.ClientMetadataService used on opensource projects

Example 31 with ClientMetadataService

use of org.apache.geode.cache.client.internal.ClientMetadataService in project geode by apache.

the class FixedPRSinglehopDUnitTest method verifyEmptyMetadata.

public static void verifyEmptyMetadata() {
    ClientMetadataService cms = ((GemFireCacheImpl) cache).getClientMetadataService();
    assertTrue(cms.getClientPRMetadata_TEST_ONLY().isEmpty());
}

Example 32 with ClientMetadataService

use of org.apache.geode.cache.client.internal.ClientMetadataService in project geode by apache.

the class FixedPRSinglehopDUnitTest method verifyEmptyStaticData.

public static void verifyEmptyStaticData() {
    ClientMetadataService cms = ((GemFireCacheImpl) cache).getClientMetadataService();
    assertTrue(cms.getClientPartitionAttributesMap().isEmpty());
}

Example 33 with ClientMetadataService

use of org.apache.geode.cache.client.internal.ClientMetadataService in project geode by apache.

the class FixedPRSinglehopDUnitTest method testMetadataInClientWithFixedPartitions.

/**
   * This test will check to see if all the partitionAttributes are sent to the client. In case one
   * partition comes late, we should fetch that when there is a network hop because of that
   * partitioned region. This test will create 3 servers with partition. Do some operations on them.
   * Validate that the metadata are fetched and then later up one more partition and do some
   * operations on them. It should fetch new fpa. Verify that the correct servers are known to the
   * client metadata service at the end.
