A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.
Public Constructors | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Constructs a PropertyDescriptor for a property that follows
the standard Java convention by having getFoo and setFoo
accessor methods.
| |||||||||||
This constructor takes the name of a simple property, and method
names for reading and writing the property.

This constructor takes the name of a simple property, and Method
objects for reading and writing the property.

Public Methods | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Constructs an instance of a property editor using the current
property editor class.

Compares this
PropertyDescriptor against the specified object. | |||||||||||
Gets any explicit PropertyEditor Class that has been registered
for this property.
| |||||||||||
Gets the Class object for the property.

| |||||||||||
Returns a hash code value for the object.
| |||||||||||
Updates to "bound" properties will cause a "PropertyChange" event to
get fired when the property is changed.
| |||||||||||
Attempted updates to "Constrained" properties will cause a "VetoableChange"
event to get fired when the property is changed.

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 writer method is "setFred" and the reader method is "getFred" (or "isFred" for a boolean property). Note that the property name should start with a lower case character, which will be capitalized in the method names.
propertyName | The programmatic name of the property. |
---|---|
beanClass | The Class object for the target bean. For example sun.beans.OurButton.class. |
IntrospectionException | if an exception occurs during introspection. |

beanClass | The Class object for the target bean. For example sun.beans.OurButton.class. |
readMethodName | The name of the method used for reading the property value. May be null if the property is write-only. |
writeMethodName | The name of the method used for writing the property value. May be null if the property is read-only. |

IntrospectionException | if an exception occurs during introspection. |
---|
Constructs an instance of a property editor using the current property editor class.
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.
bean | the source object |
---|
Compares this PropertyDescriptor
against the specified object.
Returns true if the objects are the same. Two PropertyDescriptor
s
are the same if the read, write, property types, property editor and
flags are equivalent.
obj | the reference object with which to compare. |
---|
true
if this object is the same as the obj
argument; false
otherwise.Gets any explicit PropertyEditor Class that has been registered for this property.
Gets the Class object for the property.
This is the type that will be returned by the ReadMethod.
Gets the method that should be used to read the property value.
Gets the method that should be used to write the property value.
Returns a hash code value for the object.
See hashCode()
for a complete description.
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
Updates to "bound" properties will cause a "PropertyChange" event to get fired when the property is changed.
bound | True if this is a bound property. |
---|
Attempted updates to "Constrained" properties will cause a "VetoableChange" event to get fired when the property is changed.
constrained | True if this is a constrained property. |

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.
propertyEditorClass | The Class for the desired PropertyEditor. |

Sets the method that should be used to read the property value.
readMethod | The new read method. |

IntrospectionException |

Sets the method that should be used to write the property value.
writeMethod | The new write method. |
