Class UlidConverter

java.lang.Object
com.broadleafcommerce.data.tracking.jpa.UlidConverter
All Implemented Interfaces:
javax.persistence.AttributeConverter<String,byte[]>
public class UlidConverter extends Object implements javax.persistence.AttributeConverter<String,byte[]>
Serves to convert the string ULID representation of the field in the Java entity class into the byte array representation for storage in a binary field in the database. This can serve to save some memory space in the database (especially for indexed fields) at the cost of readability and easy data troubleshooting. There is a string passthrough version of this converter as well. Which version is used is determined by which library is mounted on the classpath at runtime.

String fields in an entity class that should receive this persistence behaviour should be annotated with @Convert(converter = UlidConverter.class).
