Example 21 with Engine

use of com.google.refine.browsing.Engine in project OpenRefine by OpenRefine.

the class EngineDependentMassCellOperation method createHistoryEntry.

@Override

    }
    List<CellChange> cellChanges = new ArrayList<CellChange>(project.rows.size());
    FilteredRows filteredRows = engine.getAllFilteredRows();
    try {
        filteredRows.accept(project, createRowVisitor(project, cellChanges, historyEntryID));
    } catch (Exception e) {
        e.printStackTrace();
    }
    String description = createDescription(column, cellChanges);
    return new HistoryEntry(historyEntryID, project, description, this, createChange(project, column, cellChanges));
}

Example 22 with Engine

use of com.google.refine.browsing.Engine in project OpenRefine by OpenRefine.

the class EngineDependentOperation method createEngine.

protected Engine createEngine(Project project) throws Exception {
    Engine engine = new Engine(project);
    engine.initializeFromJSON(getEngineConfig());
    return engine;
}

Example 23 with Engine

use of com.google.refine.browsing.Engine in project OpenRefine by OpenRefine.

the class CommandTests method getEngineRegressionTest.

@Test
public void getEngineRegressionTest() {
    // TODO refactor getEngine to use dependency injection, so a mock Engine
    // object can be used.
    Engine engine = null;
    when(request.getParameter("engine")).thenReturn("{\"hello\":\"world\"}");
    try {
        engine = SUT.wrapGetEngine(request, project);
        Assert.assertNotNull(engine);
    } catch (Exception e) {
        Assert.fail();
    }
    verify(request, times(1)).getParameter("engine");
// JSON configuration doesn't have 'facets' key or 'INCLUDE_DEPENDENT'
// key, so there should be no further action
// Engine._facets is protected so can't test that it is of zero length.
}

}

Example 25 with Engine

use of com.google.refine.browsing.Engine in project OpenRefine by OpenRefine.

the class RowStarOperation method createHistoryEntry.

@Override
