use of io.crate.expression.reference.DocRefResolver in project crate by crate.

the class GeneratedColumnsTest method testSubscriptExpressionThatReturnsAnArray.

@Test

    GeneratedColumns<Doc> generatedColumns = new GeneratedColumns<>(new InputFactory(e.nodeCtx), CoordinatorTxnCtx.systemTransactionContext(), GeneratedColumns.Validation.NONE, new DocRefResolver(Collections.emptyList()), Collections.emptyList(), table.generatedColumns());
    BytesReference bytes = BytesReference.bytes(XContentFactory.jsonBuilder().startObject().startObject("obj").startArray("arr").value(10).value(20).endArray().endObject().endObject());
    generatedColumns.setNextRow(new Doc(1, table.concreteIndices()[0], "1", 1, 1, 1, XContentHelper.convertToMap(bytes, false, XContentType.JSON).v2(), bytes::utf8ToString));
