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 | Description |
|---|---|
IndexedPropertyDescriptor |
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 |
This constructor takes the name of a simple property, and method names for reading and writing the property, both indexed and non-indexed. |
IndexedPropertyDescriptor |
This constructor takes the name of a simple property, and Method objects for reading and writing the property. |
| Modifier and Type | Method | Description |
|---|---|---|
boolean |
equals |
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 |
Sets the method that should be used to read an indexed property value. |
void |
setIndexedWriteMethod |
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".

Class object may describe primitive Java types such as int. This type is returned by the indexed read method or is used as the parameter type of the indexed write method.Class object that represents the Java type info, or null if the type cannot be determinedpublic 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 PropertyDescriptor
obj - the reference object with which to compare.true if this object is the same as the obj argument; false otherwise.public int hashCode()
Object.hashCode() for a complete description.hashCode in class PropertyDescriptor
