Method Detail

hasAttribute

public static boolean hasAttribute(Identified identified_obj,
                                   String attribute)
                            throws WTIntrospectionException,
                                   WTException

Method hasAttribute determines if the given Identified object has an attribute with the given name.

Parameters:

identified_obj - the Identified object to check for the given attribute

attribute - the String name of the attribute to check for in the given object

Returns:

true if the given object has an attribute of the given name

Throws:

WTIntrospectionException - if an error occurs while ` looking for the given attribute name in the given Identified object

WTException - if an error occurs while looking for the given attribute name in the given Identified object

setAttribute

public static Identified setAttribute(Identified identified_obj,
                                      String attribute,
                                      String value)
                               throws WTIntrospectionException,
                                      WTException

Method setAttribute attempts to set the attribute value specified by the given name on the given object to the given value. This method assumes that the attribute specified by the given name takes a String value. Introspection is used to attempt to retrieve the appropriate setter method and invoke it. The updated Identified object is returned.

Parameters:

attribute - the String name of the attribute whose value is to be set

value - the String value used to set the attribute specified by the given name on the given object

Returns:

the updated Identified object

Throws:

WTIntrospectionException - if an error occurs attempting to invoke the setter method for the given attribute on the given object

WTException - if an error occurs attempting to invoke the setter method for the given attribute on the given object

getAttribute

public static String getAttribute(Identified identified_obj,
                                  String attribute)
                           throws WTIntrospectionException,
                                  WTException

Method getAttribute retrieves the value of the attribute specified by the given String name from the given Identified object. Introspection is used to attempt to retrieve the appropriate getter method and invoke it.

Parameters:

identified_obj - the Identified object on which to retrieve the given attribute

attribute - the String name of the attribute whose value is to be retrieved

Returns:

the String value corresponding to the given attribute

Throws:

WTIntrospectionException - if an error occurs attempting to find the appropriate getter method and invoke it

WTException - if an error occurs invoking the getter method for the given attribute name

getObjectPropertyDescriptor

protected static PropertyDescriptor getObjectPropertyDescriptor(Identified identified_obj,
                                                                String attribute)

Utility method to retrieve PropertyDescriptor of modelled attributes on Persistable objects. Note that this method gets the PropertyDescriptor of attributes directly on the Identified object and not on the IdentificationObject.

Throws:

WTIntrospectionException

WTException
