    assertSame(ProjectionFilter.PROJECT_NONE, ProjectionFilter.providedSchemaFilter(Projections.projectNone(), schema, EmptyErrorContext.INSTANCE));
    assertSame(ProjectionFilter.PROJECT_ALL, ProjectionFilter.providedSchemaFilter(Projections.projectAll(), new TupleSchema(), EmptyErrorContext.INSTANCE));
    TupleMetadata strictEmpty = new TupleSchema();
    strictEmpty.setBooleanProperty(TupleMetadata.IS_STRICT_SCHEMA_PROP, true);
    assertSame(ProjectionFilter.PROJECT_NONE, ProjectionFilter.providedSchemaFilter(Projections.projectAll(), strictEmpty, EmptyErrorContext.INSTANCE));
    assertTrue(ProjectionFilter.providedSchemaFilter(Projections.parse(RowSetTestUtils.projectList("a")), schema, EmptyErrorContext.INSTANCE) instanceof CompoundProjectionFilter);
}

Example 2 with SchemaProjectionFilter

use of org.apache.drill.exec.physical.resultSet.impl.ProjectionFilter.SchemaProjectionFilter in project drill by apache.

the class TestProjectionFilter method testCompoundMap.

@Test

    TupleMetadata schema = new SchemaBuilder().add(A_COL.copy()).add(B_COL.copy()).addMap("m").add("a", MinorType.INT).add("b", MinorType.INT).resumeSchema().build();
    ProjectionFilter filter = new CompoundProjectionFilter(new DirectProjectionFilter(Projections.parse(RowSetTestUtils.projectList("a", "c", "m.a")), EmptyErrorContext.INSTANCE), new SchemaProjectionFilter(schema, EmptyErrorContext.INSTANCE));
    ProjResult result = filter.projection(MAP_COL);
    assertTrue(result.isProjected);
    assertTrue(result.mapFilter.isProjected("a"));
}
