Annotation Type TextAdapter

@Documented
@Retention(value=RUNTIME)
@Target(value=METHOD)
@AdapterDefinition(storageTypePreferences={java.lang.String.class,Clob.class,Blob.class})
public @interface TextAdapter

Converts database Blobs and Clobs to Strings. This is suitable for text values which are expected to fit entirely in memory. The storage layer will attempt to store the text as a regular string, but will use a blob type if required to.

Example:

 public interface UserInfo extends Storable {
     @TextAdapter(charset="UTF-8")
     String getWelcomeMessage();
     void setWelcomeMessage(String message);

     ...
 }
