IndexedPropertyDescriptor
public class PropertyDescriptor extends FeatureDescriptor
Constructor | Description |
---|---|
PropertyDescriptor |
Constructs a PropertyDescriptor for a property that follows the standard Java convention by having getFoo and setFoo accessor methods. |
PropertyDescriptor |
This constructor takes the name of a simple property, and method names for reading and writing the property. |
PropertyDescriptor |
This constructor takes the name of a simple property, and Method objects for reading and writing the property. |
Modifier and Type | Method | Description |
---|---|---|
PropertyEditor |
createPropertyEditor |
Constructs an instance of a property editor using the current property editor class. |
boolean |
equals |
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 |
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed. |
void |
setConstrained |
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed. |
void |
setPropertyEditorClass |
Normally PropertyEditors will be found using the PropertyEditorManager. |
void |
setReadMethod |
Sets the method that should be used to read the property value. |
void |
setWriteMethod |
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.
