- public class IndexedPropertyDescriptor
- extends PropertyDescriptor
An IndexedPropertyDescriptor describes a property that acts like an
array and has an indexed read and/or indexed write method to access
specific elements of the array.
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 Summary
|
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 getterName,
String setterName,
String indexedGetterName,
String indexedSetterName)
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 getter,
Method setter,
Method indexedGetter,
Method indexedSetter)
This constructor takes the name of a simple property, and Method
objects for reading and writing the property.

IndexedPropertyDescriptor
public IndexedPropertyDescriptor(String propertyName,
Class beanClass) throws IntrospectionException
- 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.
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".
- Parameters:
propertyName
- The programmatic name of the property.
beanClass
- The Class object for the target bean.
- Throws:
- IntrospectionException - if an exception occurs during
introspection.
IndexedPropertyDescriptor
public IndexedPropertyDescriptor(String propertyName,
Class beanClass,
String getterName,
String setterName,
String indexedGetterName,
String indexedSetterName) throws IntrospectionException
- This constructor takes the name of a simple property, and method
names for reading and writing the property, both indexed
and non-indexed.
- Parameters:
propertyName
- The programmatic name of the property.
beanClass
- The Class object for the target bean.
getterName
- The name of the method used for reading the property
values as an array. May be null if the property is write-only
or must be indexed.
setterName
- The name of the method used for writing the property
values as an array. May be null if the property is read-only
or must be indexed.
indexedGetterName
- The name of the method used for reading
an indexed property value.
May be null if the property is write-only.
indexedSetterName
- The name of the method used for writing
an indexed property value.
May be null if the property is read-only.
- Throws:
- IntrospectionException - if an exception occurs during
introspection.
IndexedPropertyDescriptor
public IndexedPropertyDescriptor(String propertyName,
Method getter,
Method setter,
Method indexedGetter,
Method indexedSetter) throws IntrospectionException
- This constructor takes the name of a simple property, and Method
objects for reading and writing the property.
- Parameters:
propertyName
- The programmatic name of the property.
getter
- The method used for reading the property values as an array.
May be null if the property is write-only or must be indexed.
setter
- The method used for writing the property values as an array.
May be null if the property is read-only or must be indexed.
indexedGetter
- The method used for reading an indexed property value.
May be null if the property is write-only.
indexedSetter
- The method used for writing an indexed property value.
May be null if the property is read-only.
- Throws:
- IntrospectionException - if an exception occurs during
introspection.
getIndexedReadMethod
public Method getIndexedReadMethod()
- Returns:
- The method that should be used to read an indexed
property value.
May return null if the property isn't indexed or is write-only.
setIndexedReadMethod
public void setIndexedReadMethod(Method getter) throws IntrospectionException
- Set the method that should be used to read an indexed property value.
- Parameters:
getter
- The new indexed getter method.
getIndexedWriteMethod
public Method getIndexedWriteMethod()
- Returns:
- The method that should be used to write an indexed
property value.
May return null if the property isn't indexed or is read-only.
setIndexedWriteMethod
public void setIndexedWriteMethod(Method setter) throws IntrospectionException
- Set the method that should be used to write an indexed property value.
- Parameters:
getter
- The new indexed setter method.
getIndexedPropertyType
public Class getIndexedPropertyType()
- Returns:
- The Java Class for the indexed properties type. Note that
the Class may describe a primitive Java type such as "int".
This is the type that will be returned by the indexedReadMethod.
