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()
Returns the Java type info for the indexed property.
|
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.

public IndexedPropertyDescriptor(String propertyName, Class<?> beanClass) throws IntrospectionException
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".
