4.6.2.4. Parameterized Bridge

A ParameterizedBridge interface passes parameters to the bridge implementation, making it more flexible. The ParameterizedBridge interface can be implemented by StringBridge, TwoWayStringBridge, FieldBridge implementations. All implementations must be thread-safe.
The following example implements a ParameterizedBridge interface, with parameters passed through the @FieldBridge annotation.

Example 4.16. Configure the ParameterizedBridge Interface

public class PaddedIntegerBridge implements StringBridge, ParameterizedBridge {

    public static String PADDING_PROPERTY = "padding";
    private int padding = 5; //default

    public void setParameterValues(Map<String,String> parameters) {
        String padding = parameters.get( PADDING_PROPERTY );
        if (padding != null) this.padding = Integer.parseInt( padding );
    }

    public String objectToString(Object object) {
        String rawInteger = ( (Integer) object ).toString();
        if (rawInteger.length() > padding) 
            throw new IllegalArgumentException( "Try to pad on a number too big" );
        StringBuilder paddedInteger = new StringBuilder( );
        for ( int padIndex = rawInteger.length() ; padIndex < padding ; padIndex++ ) {
            paddedInteger.append('0');
        }
        return paddedInteger.append( rawInteger ).toString();
    }
}


//property
@FieldBridge(impl = PaddedIntegerBridge.class,
             params = @Parameter(name="padding", value="10")
            )
private Integer length;
