Examples with Struct org.apache.atlas.typesystem.Struct used on opensource projects

Example 11 with Struct

use of org.apache.atlas.typesystem.Struct in project incubator-atlas by apache.

the class GraphBackedMetadataRepositoryDeleteTestBase method testDeleteEntityWithTraits.

@Test
public void testDeleteEntityWithTraits() throws Exception {
    Referenceable entity = createDBEntity();
    String id = createInstance(entity);
    TraitType dataType = typeSystem.getDataType(TraitType.class, PII);
    ITypedStruct trait = dataType.convert(new Struct(TestUtils.PII), Multiplicity.REQUIRED);
    repositoryService.addTrait(id, trait);
    ITypedReferenceableInstance instance = repositoryService.getEntityDefinition(id);
    assertTrue(instance.getTraits().contains(PII));
    deleteEntities(id);
    assertEntityDeleted(id);
    assertTestDeleteEntityWithTraits(id);
}

Example 12 with Struct

use of org.apache.atlas.typesystem.Struct in project incubator-atlas by apache.

the class TypeInheritanceTest method testDiamondInheritance.

/*
     * Type Hierarchy is:
     *   A(a,b,c,d)
     *   B(b) extends A
     *   C(c) extends A
     *   D(d) extends B,C
     *
     * - There are a total of 11 fields in an instance of D
     * - an attribute that is hidden by a SubType can referenced by prefixing it with the
     * complete Path.
     *   For e.g. the 'b' attribute in A (that is a superType for B) is hidden the 'b' attribute
     *   in B.
     *   So it is availabel by the name 'A.B.D.b'
     *
     * - Another way to set attributes is to cast. Casting a 'D' instance of 'B' makes the 'A.B.D
     * .b' attribute
     *   available as 'A.B.b'. Casting one more time to an 'A' makes the 'A.B.b' attribute
     *   available as 'b'.
