the class TbGetTelemetryNodeTest method givenAggregationAsString_whenParseAggregation_thenReturnEnum.

@Test
public void givenAggregationAsString_whenParseAggregation_thenReturnEnum() {
    // compatibility with old configs without "aggregation" parameter
    assertThat(node.parseAggregationConfig(null), is(Aggregation.NONE));
    assertThat(node.parseAggregationConfig(""), is(Aggregation.NONE));
    // common values
    assertThat(node.parseAggregationConfig("MIN"), is(Aggregation.MIN));

    assertThat(node.parseAggregationConfig("COUNT"), is(Aggregation.COUNT));
    assertThat(node.parseAggregationConfig("NONE"), is(Aggregation.NONE));
    // all possible values in future
    for (Aggregation aggEnum : Aggregation.values()) {
        assertThat(node.parseAggregationConfig(aggEnum.name()), is(aggEnum));
    }
}

Example 2 with Aggregation

use of org.thingsboard.server.common.data.kv.Aggregation in project thingsboard by thingsboard.

the class CassandraBaseTimeseriesDao method findAndAggregateAsync.
