java.lang.Class<C>	componentType() Used to ensure that the parameterization of the component type of the indexed property won't cause problems for the PropertyHandler.
C	get(PropertyValues values, java.lang.String propertyName, int index) Invoked by the PropertyHandler when a read is performed against a specified indexed property, alternate that returns the element at the specified index, rather than the entire array.
void	set(PropertyValues values, java.lang.String propertyName, int index, C value) Invoked by the PropertyHandler when a write is performed against a specified indexed property, alternate that sets the element at the specified index, rather than the entire array.

Method Detail

componentType

java.lang.Class<C> componentType()

Used to ensure that the parameterization of the component type of the indexed property won't cause problems for the PropertyHandler.

Returns:

Should match the component type of the T parameters, which will be checked to ensure it is an array.

get

C get(PropertyValues values,
      java.lang.String propertyName,
      int index)

Invoked by the PropertyHandler when a read is performed against a specified indexed property, alternate that returns the element at the specified index, rather than the entire array.

Parameters:

values - Gives the delegate access to the internal state of the bean.

propertyName - Discriminates which property is being accessed, so a single delegate can intelligently be re-used.

index - Element to manipulate.

Returns:

Must match the property type or will cause an InvocationTargetException.

set

void set(PropertyValues values,
         java.lang.String propertyName,
         int index,
         C value)

Invoked by the PropertyHandler when a write is performed against a specified indexed property, alternate that sets the element at the specified index, rather than the entire array.

Parameters:

values - Gives the delegate access to the internal state of the bean.

propertyName - Discriminates which property is being accessed, so a single delegate can intelligently be re-used.

index - Element to manipulate.
