Example 1 with FlexBean

use of org.jaffa.flexfields.FlexBean in project jaffa-framework by jaffa-projects.

the class BeanHelper method setField.

/**
 * This method will introspect the bean & get the setter method for the input propertyName.
 * It will then try & convert the propertyValue to the appropriate datatype.
 * Finally it will invoke the setter.
 * @return A true indicates, the property was succesfully set to the passed value. A false indicates the property doesn't exist or the propertyValue passed is not compatible with the setter.
 * @param bean The bean class to be introspected.
 * @param propertyName The Property being searched for.
 * @param propertyValue The value to be set.
 * @throws IntrospectionException if an exception occurs during introspection.
 * @throws IllegalAccessException if the underlying method is inaccessible.
 * @throws InvocationTargetException if the underlying method throws an exception.
