Method Detail

registerEditor

public static void registerEditor(java.lang.Class beanClass,
                                  java.lang.Class editorClass)

see BeanBindingDemo2.java

Parameters:

beanClass - the bean class, e.g. Datum.class

editorClass - the editor class, e.g. DatumEditor.class

findEditor

public static java.beans.PropertyEditor findEditor(java.lang.Class propertyClass)

getEditor

public static java.beans.PropertyEditor getEditor(java.beans.PropertyDescriptor pd)

One-stop place to get the editor for the given propertyDescriptor.

Parameters:

pd - the property descriptor

Returns:

the editor

getPropertyDescriptors

public static java.beans.PropertyDescriptor[] getPropertyDescriptors(java.lang.Class c)

Use reflection to get a list of all the property names for the class. The properties are returned in the order specified, and put inherited properties at the end of the list. Implement the include/exclude logic. This will not return write-only descriptors!!!

getBeanInfo

public static java.beans.BeanInfo getBeanInfo(java.lang.Class c)
                                       throws java.beans.IntrospectionException

Throws:

java.beans.IntrospectionException

getPropertyNames

public static java.lang.String[] getPropertyNames(java.beans.PropertyDescriptor[] propertyList)

getPropertyNames

public static java.lang.String[] getPropertyNames(java.lang.Class c)

Use reflection to get a list of all the property names for the class. The properties are returned in the order specified, and put inherited properties at the end of the list. This is motivated by the arbitrary order that the Introspector presents the properties, which is in conflict with our desire to control the property order.

asAccessLevelBeanInfo

public static AccessLevelBeanInfo asAccessLevelBeanInfo(java.beans.BeanInfo beanInfo,
                                                        java.lang.Class beanClass)

Returns an AccessLevelBeanInfo for the BeanInfo class, implementing the logic of how to handle implicit properties.
