Class AdlSqlTypeDecorator

java.lang.Object
de.calamanari.adl.sql.AdlSqlTypeDecorator
All Implemented Interfaces:
de.calamanari.adl.cnv.tps.AdlType, AdlSqlType, Serializable
public class AdlSqlTypeDecorator extends Object implements AdlSqlType
Often an AdlSqlTypes behavior will be common resp. applicable in many scenarios but we want to change the formatter or add a type caster. To avoid creating boiler-plate code the AdlSqlTypeDecorator provides an easy solution by composition. A given type gets wrapped to adapt its behavior.
