Example 1 with ReferenceableInstance

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

the class GraphHelper method getTypedReferenceableInstance.

public static ITypedReferenceableInstance getTypedReferenceableInstance(TypeSystem typeSystem, Referenceable entityInstance) throws AtlasException {

    ClassType entityType = typeSystem.getDataType(ClassType.class, entityTypeName);
    //Both assigned id and values are required for full update
    //classtype.convert() will remove values if id is assigned. So, set temp id, convert and
    // then replace with original id
    Id origId = entityInstance.getId();
    entityInstance.replaceWithNewId(new Id(entityInstance.getTypeName()));
