StructConverter (EclipseLink 2.7.15, API Reference)

```
public interface StructConverter
```
PUBLIC: A StuctConverter can be added to a DatabasePlatform It allows custom processing dealing java.sql.Struct types When added to the DatabasePlatform: 1. convertToObject(Struct) will be invoked when a Struct named by the value returned by getStructName() is returned from the database. This conversion happens immediately after the object is returned from the database 2. convertToStruct(Object, Connection) will be invoked when an Object of the class returned by getJavaType() is written to the database. This conversion happens immediately before the object is written to the database Note: Many Structs can also be mapped with mappings StructureMapping and ObjectRelationalDataTypeDescriptor This class provides support for advanced types of Structures that require some processing immediately before writing to the database or immediately after reading from the database.
