Method Detail

getProperties

public java.util.Properties getProperties(java.lang.Class aClass,
                                          java.lang.String resourceName)

getInstance

public static PropertiesManager getInstance()

initializeBeanFrom

public void initializeBeanFrom(java.lang.Object bean,
                               java.util.Properties properties)
                        throws InitializeFromPropertiesException

This method introspects a Java Bean and for all writeable bean properties, it looks in the provided properties file to get a value which will be used to set the property.

Example:

Suppose the Java Bean had three properties:

1. lastName : String
2. firstName : String
3. bankBalance : BigDecimal

This method will look in the properties file for each of these properties and will then call the appropriate set methods (setLastName(), setFirstName(), and setBankBalance()).

To handle the bankBalance (and other non-String classes), this method will look for a constructor that takes a String parameter, and perform the equivalent of new BigDecimal("12345.67").

This method knows how to handle the standard primitive types; an int property, for example, will be set by first calling the new Integer(propertyValueAsString) constructor of the object type.
