Examples of org.lilyproject.repository.api.FieldTypeEntry

org.lilyproject.repository.api.FieldTypeEntry
Describes the association between a {@link RecordType} and a {@link FieldType}. Or in other words, the occurrence of a field type within a record type.
At this time, the only attribute specific to this relation indicates if the field type is mandatory within the record type.
Field type entries are added to record types via {@link RecordType#addFieldTypeEntry(FieldTypeEntry) RecordType.addFieldTypeEntry} and instantiated via{@link TypeManager#newFieldTypeEntry(String,boolean) TypeManager.newFieldTypeEntry}. As all entities within this API, field type entries are dumb data objects.

        FieldType fieldType = typeManager.newFieldType(typeManager.getValueType("PATH<BLOB>"), fieldName,
                Scope.VERSIONED_MUTABLE);
        fieldType = typeManager.createFieldType(fieldType);
        RecordType recordType = typeManager.newRecordType(new QName(namespace, "testUpdateMutableHierarchyBlobRT"
                + size));
        FieldTypeEntry fieldTypeEntry = typeManager.newFieldTypeEntry(fieldType.getId(), true);
        recordType.addFieldTypeEntry(fieldTypeEntry);
        recordType = typeManager.createRecordType(recordType);


        byte[] bytes = new byte[size];
        random.nextBytes(bytes);
