public class PropertyDescriptor extends FeatureDescriptor
| Constructor and Description |
|---|
PropertyDescriptor(String propertyName,
Class<?> beanClass)
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 readMethodName,
String writeMethodName)
This constructor takes the name of a simple property, and method
names for reading and writing the property.
|
PropertyDescriptor(String propertyName,
Method readMethod,
Method writeMethod)
This constructor takes the name of a simple property, and Method
objects for reading and writing the property.
|
| Modifier and Type | Method and Description |
|---|---|
PropertyEditor |
createPropertyEditor(Object bean)
Constructs an instance of a property editor using the current
property editor class.
|
boolean |
equals(Object obj)
Compares this
PropertyDescriptor against the specified object. |
Class<?> |
getPropertyEditorClass()
Gets any explicit PropertyEditor Class that has been registered
for this property.
|
Class<?> |
getPropertyType()
Returns the Java type info for the property.
|
Method |
getReadMethod()
Gets the method that should be used to read the property value.
|
Method |
getWriteMethod()
Gets the method that should be used to write the property value.
|
int |
hashCode()
Returns a hash code value for the object.
|
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(Method readMethod)
Sets the method that should be used to read the property value.
|
void |
setWriteMethod(Method writeMethod)
Sets the method that should be used to write the property value.

public PropertyEditor createPropertyEditor(Object bean)
If the property editor class has a public constructor that takes an Object argument then it will be invoked using the bean parameter as the argument. Otherwise, the default constructor will be invoked.
