Example 83 with ColumnCapabilities

use of org.apache.druid.segment.column.ColumnCapabilities in project druid by apache.

the class RowBasedColumnSelectorFactoryTest method testCapabilitiesUnknownColumn.

Example 84 with ColumnCapabilities

use of org.apache.druid.segment.column.ColumnCapabilities in project druid by apache.

the class RowBasedStorageAdapterTest method test_getColumnCapabilities_float.

@Test
public void test_getColumnCapabilities_float() {
    final RowBasedStorageAdapter<Integer> adapter = createIntAdapter(0, 1, 2);
    final ColumnCapabilities capabilities = adapter.getColumnCapabilities(ValueType.FLOAT.name());
    Assert.assertEquals(ValueType.FLOAT, capabilities.getType());
    Assert.assertFalse(capabilities.hasMultipleValues().isMaybeTrue());
}

Example 85 with ColumnCapabilities

use of org.apache.druid.segment.column.ColumnCapabilities in project druid by apache.

the class RowBasedStorageAdapterTest method test_getColumnCapabilities_string.

@Test
public void test_getColumnCapabilities_string() {
    final RowBasedStorageAdapter<Integer> adapter = createIntAdapter(0, 1, 2);
    final ColumnCapabilities capabilities = adapter.getColumnCapabilities(ValueType.STRING.name());
    Assert.assertEquals(ValueType.STRING, capabilities.getType());
    // Note: unlike numeric types, STRING-typed columns might have multiple values, so they report as incomplete. It
    // would be good in the future to support some way of changing this, when it is known ahead of time that
    // multi-valuedness is definitely happening or is definitely impossible.
    Assert.assertTrue(capabilities.hasMultipleValues().isUnknown());
