public class PropertyDescriptor
extends FeatureDescriptor
A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.

Constructor Index

o PropertyDescriptor(String, Method, Method)
This constructor takes the name of a simple property, and Method objects for reading and writing the property.
o PropertyDescriptor(String, String)
This constructor constructs a PropertyDescriptor for a property that follows the standard Java convention by having getFoo and setFoo accessor methods.
o PropertyDescriptor(String, String, String, String)
This constructor takes the name of a simple property, and method names for reading and writing the property.

Method Index

o getPropertyEditorClass()
o getPropertyType()
o getReadMethod()
o getWriteMethod()
o isBound()
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
o isConstrained()
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
o setBound(boolean)
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
o setConstrained(boolean)
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
o setPropertyEditorClass(Class)
Normally PropertyEditors will be found using the PropertyEditorManager.

Constructors

o PropertyDescriptor 
  public PropertyDescriptor(String propertyName,
                            String beanClassName) throws IntrospectionException
This constructor constructs a PropertyDescriptor for a property that follows the standard Java convention by having getFoo and setFoo accessor methods. Thus if the argument name is "fred", it will assume that the reader method is "getFred" and the writer method is "setFred". Note that the property name should start with a lower case character, which will be capitalized in the method names.
Parameters:
propertyName - The programmatic name of the property.
beanClassName - The full class name for the target bean. For example "sun.beans.OurButton".
o PropertyDescriptor 
  public PropertyDescriptor(String propertyName,
                            String beanClassName,
                            String getterName,
                            String setterName) throws IntrospectionException
This constructor takes the name of a simple property, and method names for reading and writing the property.
Parameters:
propertyName - The programmatic name of the property.
beanClassName - The full class name for the target bean. For example "sun.beans.OurButton".
getterName - The name of the method used for reading the property value. May be null if the property is write-only.
setterName - The name of the method used for writing the property value. May be null if the property is read-only.
o PropertyDescriptor 
  public PropertyDescriptor(String propertyName,
                            Method getter,
                            Method setter) throws IntrospectionException
This constructor takes the name of a simple property, and Method objects for reading and writing the property.
Parameters:
propertyName - The programmatic name of the property.
getter - The method used for reading the property value. May be null if the property is write-only.
setter - The method used for writing the property value. May be null if the property is read-only.

Methods

o getPropertyType 
  public Class getPropertyType()
Returns:
The Java type info for the property. Note that the "Class" object may describe a built-in Java type such as "int".

This is the type that will be returned by the ReadMethod.

o getReadMethod 
  public Method getReadMethod()
Returns:
The method that should be used to read the property value. May return null if the property can't be read.
o getWriteMethod 
  public Method getWriteMethod()
Returns:
The method that should be used to write the property value. May return null if the property can't be written.
o isBound 
  public boolean isBound()
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
Returns:
True if this is a bound property.
o setBound 
  public void setBound(boolean bound)
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
Parameters:
bound - True if this is a bound property.
o isConstrained 
  public boolean isConstrained()
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
Returns:
True if this is a constrained property.
o setConstrained 
  public void setConstrained(boolean constrained)
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
Parameters:
constrained - True if this is a constrained property.
o setPropertyEditorClass 
  public void setPropertyEditorClass(Class propertyEditorClass)
Normally PropertyEditors will be found using the PropertyEditorManager. However if for some reason you want to associate a particular PropertyEditor with a given property, then you can do it with this method.
Parameters:
propertyEditorClass - The Class for the desired PropertyEditor.
o getPropertyEditorClass 
  public Class getPropertyEditorClass()
Returns:
Any explicit PropertyEditor Class that has been registered for this property. Normally this will return "null", indicating that no special editor has been registered, so the PropertyEditorManager should be used to locate a suitable PropertyEditor.
