Examples of FieldConverter

com.j256.ormlite.field.FieldConverter
Convert a Java object into the appropriate argument to a SQL statement and then back from the result set to the Java object. This allows databases to configure per-type conversion. This is used by the {@link BaseDatabaseType#getFieldConverter(DataPersister)} method to find the converter for a particular databasetype. Databases can then override the default data conversion mechanisms as necessary. @author graywatson
