Type-safe "enumeration" of the GDS types registered in the system.
 
 public final class GDSType implements Serializable {
     
     private final static HashMap typeMap = new HashMap();
 
     // Getter for the typeMap variable, please note that static initializer of

Factory method for instances of this class. There's only three possible instances of this class, however linking to them directly is not always possible and desirable (for example when type is specified in configuration). This method gives the possibility to translate string representation of the type into correct type instance.

Parameters:
type string representation of the type to match (matching is case insensitive). Possible values are:
  • "PURE_JAVA" or "TYPE4" for pure Java (type 4) driver version;
  • "NATIVE" or "TYPE2" for type 2 JDBC driver that will use Firebird client library to access the database using JNI link.
  • "EMBEDDED" for type 2 JDBC driver that will use embedded version of the server to perform database-related operations.
Returns:
instance of GDSType corresponding to the specified string representation or null if no match could be found.
 
     public static GDSType getType(String type) {
         if (type == null)
             return null;
             
         return (GDSType)getTypeMap().get(type.toUpperCase());
     }
    
    
Register the GDS type. Method can be called only by GDSFactory.registerPlugin(org.firebirdsql.gds.impl.GDSFactoryPlugin) method.

Parameters:
typeName name of the GDS type.
Returns:
instance of GDSType corresponding to the specified type name.
 
     static GDSType registerType(String typeName) {
         HashMap typeMap = getTypeMap();
         
         synchronized(typeMap) {
             if (typeMap.containsKey(typeName))
                 return (GDSType)typeMap.get(typeName);
             
             GDSType type = new GDSType(typeName);
             typeMap.put(typeNametype);
             
             return type;
         }
     }
     
    private GDSType(String s) {
         = s;
    }
    public Object readResolve() {
        return registerType();
    }
    public String toString() {
        return ;
    }
    private final String name;
