Constructor Detail

PojoPropertyAccessorProxyGetIndexed

public PojoPropertyAccessorProxyGetIndexed(PojoDescriptorDependencies dependencies,
                                           PojoPropertyAccessorNonArg containerGetAccessor)

The constructor.

Parameters:

dependencies - are the PojoDescriptorDependencies to use.

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

Method Detail

getMode

public PojoPropertyAccessorIndexedNonArgMode getMode()

This method gets the mode of this accessor.

Specified by:

getMode in interface PojoPropertyAccessor

Specified by:

getMode in interface PojoPropertyAccessorIndexedNonArg

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.

See Also:

Method.getReturnType(), Field.getType()

invoke

public Object invoke(Object pojoInstance,
                     int index)

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

Specified by:

invoke in interface PojoPropertyAccessorIndexedNonArg

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 (e.g. where to get or remove an item).

Returns:

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