Examples with ReferenceImplementation io.crate.metadata.ReferenceImplementation used on opensource projects

Example 1 with ReferenceImplementation

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

@Test
public void testOsTimestampNotEvaluatedTwice() throws Exception {
    ExtendedOsStats osStats = mock(ExtendedOsStats.class);
    NodeOsExpression nodeOsExpression = new NodeOsExpression(osStats);
    ReferenceImplementation timestampExpr = nodeOsExpression.getChildImplementation("timestamp");
    Long ts1 = (Long) timestampExpr.value();
    Thread.sleep(10L);
    Long ts2 = (Long) timestampExpr.value();
    assertEquals(ts1, ts2);
}

Example 2 with ReferenceImplementation

Example 5 with ReferenceImplementation

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

            //noinspection unchecked
            ((RowCollectExpression) referenceImplementation).setNextRow(this.row);
        }
        Object value = referenceImplementation.value();
        // as we do not want to convert them when building the response
        if (value instanceof BytesRef) {
            value = ((BytesRef) value).utf8ToString();
        }
        map.put(e.getKey(), value);
    }
    return Collections.unmodifiableMap(map);
