Example 6 with ReferenceImplementation

use of io.crate.metadata.ReferenceImplementation in project crate by crate.

@Test
public void testName() throws Exception {
    Reference refInfo = refInfo("sys.nodes.name", DataTypes.STRING, RowGranularity.NODE);
    @SuppressWarnings("unchecked") ReferenceImplementation<BytesRef> name = (ReferenceImplementation<BytesRef>) resolver.getChildImplementation(refInfo.ident().columnIdent().name());
    assertEquals(new BytesRef("node 1"), name.value());
}
