Constructs a PropertyDescriptor for a property that follows the standard Java convention by having getFoo and setFoo accessor methods. |
|
PropertyDescriptor(String propertyName,
Class beanClass,
String getterName,
String setterName)
This constructor takes the name of a simple property, and method names for reading and writing the property. |
|

getReadMethod()
Gets the method that should be used to read the property value. |
java.lang.reflect.Method |
getWriteMethod()
Gets the method that should be used to write the property value. |
boolean |
isBound()
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed. |
boolean |
isConstrained()
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed. |
void |
setBound(boolean bound)
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed. |
void |
setConstrained(boolean constrained)
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed. |
void |
setPropertyEditorClass(Class propertyEditorClass)
Normally PropertyEditors will be found using the PropertyEditorManager. |
void |
setReadMethod(java.lang.reflect.Method getter)
Sets the method that should be used to read the property value. |
void |
setWriteMethod(java.lang.reflect.Method setter)
Sets the method that should be used to write the property value. |
