public class ValidationParameterParser

extends DefaultJetspeedParameterParser

implements org.apache.turbine.util.ParameterParser, org.apache.turbine.util.pool.Recyclable

A Turbine parameter parser with Validation built in. Validates any bean with methods that begin with validate[AttributeName]. Works with Torque-generated beans. To use this class, override the TurbineResources.properties: services.RunDataService.default.parameter.parser=org.apache.turbine.util.parser.DefaultParameterParser

Method Detail

setProperties

public void setProperties(java.lang.Object bean)
                   throws java.lang.Exception

Uses bean introspection to set writable properties of bean from the parameters, where a (case-insensitive) name match between the bean property and the parameter is looked for.

Specified by:

setProperties in interface org.apache.turbine.util.ValueParser

Parameters:

bean - An Object.

Throws:

Exception, - a generic exception.

java.lang.Exception

setMyProperty

protected void setMyProperty(java.lang.Object bean,
                             java.beans.PropertyDescriptor prop)
                      throws java.lang.Exception

Set the property 'prop' in the bean to the value of the corresponding parameters. Supports all types supported by getXXX methods plus a few more that come for free because primitives have to be wrapped before being passed to invoke anyway.

Parameters:

bean - An Object.

prop - A PropertyDescriptor.

Throws:

Exception, - a generic exception.

java.lang.Exception

getArguments

protected java.lang.Object[] getArguments(java.beans.PropertyDescriptor prop)
                                   throws java.lang.Exception

Throws:

java.lang.Exception

validateProperty

protected boolean validateProperty(java.lang.Object bean,
                                   java.beans.PropertyDescriptor prop)
                            throws java.lang.Exception

Validate a bean's property based on definition in the business object

Parameters:

bean - The bean to be validated.

prop - The bean's property descriptor

Returns:

true if validation was successful, false if validation failed

Throws:

java.lang.Exception

validateObject

protected boolean validateObject(java.beans.PropertyDescriptor prop)
                          throws java.lang.Exception

Throws:

generalValidation

protected java.lang.String generalValidation(java.lang.Object bean)
                                      throws java.lang.Exception

Validate a bean's property based on definition in the business object

Parameters:

bean - The bean to be validated.

Returns:

null if validation was successful, an error message if validation failed

Throws:

java.lang.Exception
