public class IndexedPropertyDescriptor extends PropertyDescriptor
An indexed property may also provide simple non-indexed read and write methods. If these are present, they read and write arrays of the type returned by the indexed read method.
| Constructor and Description |
|---|
IndexedPropertyDescriptor(String propertyName,
Class<?> beanClass)
This constructor constructs an IndexedPropertyDescriptor for a property
that follows the standard Java conventions by having getFoo and setFoo
accessor methods, for both indexed access and array access.
|
IndexedPropertyDescriptor(String propertyName,
Class<?> beanClass,
String readMethodName,
String writeMethodName,
String indexedReadMethodName,
String indexedWriteMethodName)
This constructor takes the name of a simple property, and method
names for reading and writing the property, both indexed
and non-indexed.
|
IndexedPropertyDescriptor(String propertyName,
Method readMethod,
Method writeMethod,
Method indexedReadMethod,
Method indexedWriteMethod)
This constructor takes the name of a simple property, and Method
objects for reading and writing the property.
|
| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(Object obj)
Compares this
PropertyDescriptor against the specified object. |
Class<?> |
getIndexedPropertyType()
Gets the
Class object of the indexed properties' type. |
Method |
getIndexedReadMethod()
Gets the method that should be used to read an indexed
property value.
|
Method |
getIndexedWriteMethod()
Gets the method that should be used to write an indexed property value.
|
int |
hashCode()
Returns a hash code value for the object.
|
void |
setIndexedReadMethod(Method readMethod)
Sets the method that should be used to read an indexed property value.
|
void |
setIndexedWriteMethod(Method writeMethod)
Sets the method that should be used to write an indexed property value.

Thus if the argument name is "fred", it will assume that there is an indexed reader method "getFred", a non-indexed (array) reader method also called "getFred", an indexed writer method "setFred", and finally a non-indexed writer method "setFred".

Class object of the indexed properties' type.
The returned Class may describe a primitive type such as int.Class for the indexed properties' type; may return null
if the type cannot be determined.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 PropertyDescriptorobj - the reference object with which to compare.true if this object is the same as the obj
