public abstract class BeanInfoSupport
extends SimpleBeanInfo

Support class for test bean beanInfo objects. It will help using the introspector to get most of the information, to then modify it at will.

To use, subclass it, create a subclass with a parameter-less constructor that:

1. Calls super(beanClass)
2. Modifies the property descriptors, bean descriptor, etc. at will.

Even before any such modifications, a resource bundle named xxxResources (where xxx is the fully qualified bean class name) will be obtained if available and used to localize the following:

• Bean's display name -- from property displayName.
• Properties' display names -- from properties propertyName.displayName.
• Properties' short descriptions -- from properties propertyName.shortDescription.

The resource bundle will be stored as the bean descriptor's "resourceBundle" attribute, so that it can be used for further localization. TestBeanGUI, for example, uses it to obtain the group's display names from properties groupName.displayName.

Constructor Detail

BeanInfoSupport

protected BeanInfoSupport(Class<? extends TestBean> beanClass)

Construct a BeanInfo for the given class.

Method Detail

property

protected PropertyDescriptor property(String name)

Get the property descriptor for the property of the given name.

Parameters:

name - property name

Returns:

descriptor for a property of that name, or null if there's none

property

protected PropertyDescriptor property(String name,
                                      TypeEditor editor)

Get the property descriptor for the property of the given name. Sets the GUITYPE to the provided editor.

Parameters:

name - property name

editor - the TypeEditor enum that describes the property editor

Returns:

descriptor for a property of that name, or null if there's none

property

protected PropertyDescriptor property(String name,
                                      Class<? extends Enum<?>> enumClass)

Get the property descriptor for the property of the given name. Sets the GUITYPE to the provided enum.

Parameters:

name - property name

enumClass - the enum class that is to be used by the editor

Returns:

descriptor for a property of that name, or null if there's none

setIcon

protected void setIcon(String resourceName)

Set the bean's 16x16 colour icon.

Parameters:

resourceName - A pathname relative to the directory holding the class file of the current class.

createPropertyGroup

protected void createPropertyGroup(String group,
                                   String[] names)

Utility method to group and order properties.

It will assign the given group name to each of the named properties, and set their order attribute so that they are shown in the given order.

The created groups will get order 1, 2, 3,... in the order in which they are created.

Parameters:

group - name of the group

names - property names in the desired order
