java.lang.Objectjava.beans.FeatureDescriptor
java.beans.PropertyDescriptor
A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.
| Constructor Summary | |
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 getterName,
String setterName)
This constructor takes the name of a simple property, and method names for reading and writing the property. |
|
PropertyDescriptor(String propertyName,
Method getter,
Method setter)
This constructor takes the name of a simple property, and Method objects for reading and writing the property. |
|
| Method Summary | |
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()
Gets the Class object 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. |
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 getter)
Sets the method that should be used to read the property value. |
void |
setWriteMethod(Method setter)
Sets the method that should be used to write the property value. |

public PropertyDescriptor(String propertyName,
Class beanClass)
throws IntrospectionException
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.
public PropertyDescriptor(String propertyName,
Class beanClass,
String getterName,
String setterName)
throws IntrospectionException
propertyName - The programmatic name of the property.beanClass - The Class object for the target bean. For
example sun.beans.OurButton.class.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.
IntrospectionException - if an exception occurs during
introspection.
public PropertyDescriptor(String propertyName,
Method getter,
Method setter)
throws IntrospectionException
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.
IntrospectionException - if an exception occurs during
introspection.| Method Detail |
public Class getPropertyType()
This is the type that will be returned by the ReadMethod.
public Method getReadMethod()
public void setReadMethod(Method getter)
throws IntrospectionException
getter - The new getter method.
IntrospectionExceptionpublic Method getWriteMethod()
public void setWriteMethod(Method setter)
throws IntrospectionException
setter - The new setter method.
IntrospectionExceptionpublic boolean isBound()
public void setBound(boolean bound)
bound - True if this is a bound property.public boolean isConstrained()
public void setConstrained(boolean constrained)
constrained - True if this is a constrained property.public void setPropertyEditorClass(Class propertyEditorClass)
propertyEditorClass - The Class for the desired PropertyEditor.public Class getPropertyEditorClass()
public boolean equals(Object obj)
PropertyDescriptor against the specified object.
Returns true if the objects are the same. Two PropertyDescriptors
are the same if the read, write, property types, property editor and
flags are equivalent.
equals in class Objectobj - the reference object with which to compare.
true if this object is the same as the obj
argument; false otherwise.Object.hashCode(),
Hashtable
