Field Detail

containerSetAccessor

private final PojoPropertyAccessorOneArg containerSetAccessor

The according setter to use if array has to be resized.

Constructor Detail

PojoPropertyAccessorProxySetIndexed

public PojoPropertyAccessorProxySetIndexed(PojoDescriptorDependencies dependencies,
                                           PojoPropertyAccessorNonArg containerGetAccessor,
                                           PojoPropertyAccessorOneArg containerSetAccessor)

The constructor.

Parameters:

dependencies - are the PojoDescriptorDependencies to use.

containerGetAccessor - is the accessor delegate that gets an array, or List property.

containerSetAccessor - is the accessor that sets the array, or List property. May be null if NOT available.

Method Detail

getMode

public PojoPropertyAccessorIndexedOneArgMode getMode()

This method gets the mode of this accessor.

Specified by:

getMode in interface PojoPropertyAccessor

Specified by:

getMode in interface PojoPropertyAccessorIndexedOneArg

Overrides:

getMode in class AbstractPojoPropertyAccessorProxy

Returns:

the access mode.

getReturnType

public GenericType<?> getReturnType()

This method gets the GenericType of the object returned when this accessor is invoked.

Specified by:

getReturnType in interface PojoPropertyAccessor

Overrides:

getReturnType in class AbstractPojoPropertyAccessorProxy

Returns:

the return type.

See Also:

Method.getGenericReturnType(), Field.getGenericType()

getReturnClass

public Class<?> getReturnClass()

This method gets the Class of the object returned when this accessor is invoked.
is a convenience method for PojoPropertyAccessor.getReturnType(). getUpperBound()

Specified by:

getReturnClass in interface PojoPropertyAccessor

Overrides:

getReturnClass in class AbstractPojoPropertyAccessorProxy

Returns:

the return class.

Method.getReturnType(), Field.getType()

invoke

public Object invoke(Object pojoInstance,
                     int index,
                     Object item)

This method invokes the according property-method of pojoInstance with the given arguments.

Specified by:

invoke in interface PojoPropertyAccessorIndexedOneArg

Parameters:

pojoInstance - is the instance of the POJO where to access the property. Has to be an instance of the type from where this accessor was created for.

index - is the position in the indexed property where to apply (e.g. set or insert) the given item.

item - is the value to apply (e.g. set or insert) as element of the indexed property.

Returns:

the result of the invocation. Will be null if void (e.g. regular setter method).
