Example 1 with IndexMetadata

use of javax.jdo.metadata.IndexMetadata in project motech by motech.

the class EntityMetadataBuilderImpl method processField.

public void processField(ClassMetadata cmd, ClassData classData, EntityDto entity, EntityType entityType, Class<?> definition, String fieldName, FieldDto field, SchemaHolder schemaHolder) {
    // Metadata for ID field has been added earlier in addIdField() method
