Constructor Detail

MapTypeMapping

public MapTypeMapping(Class<?> objectType,
              N dataTypeName,
              K keyNodeMapping,
              Collection<V> valueNodeMappings,
              ObjectAccessor objectAccessor)

Constructs a new MapTypeMapping.

Parameters:

objectType - the object type

dataTypeName - the data type name

keyNodeMapping - the node mapping for the keys of the map

valueNodeMappings - the node mappings for the values of the map

objectAccessor - the object accessor

Method Detail

getKeyNodeMapping

public final K getKeyNodeMapping()

Returns:

the node mapping for the keys of the map.

getValueNodeMappings

public final Collection<V> getValueNodeMappings()

Returns:

the node mappings for the values of the map.

getValueNodeMapping

public <T extends V> T getValueNodeMapping(D nodeDescriptor)

Returns the value node mapping for the given node descriptor.

Type Parameters:

T - the expected type of the value node mapping

Parameters:

nodeDescriptor - the node descriptor

Returns:

the value node mapping

getValueNodeMapping

public <T extends V> T getValueNodeMapping(Class<?> objectType)

Returns the value node mapping for a map value object with the given object type. If none is registered for the object type the one for its super type is returned (and so on).

Type Parameters:

T - the expected type of the node mapping

Parameters:

objectType - the object type.

Returns:

the element mapping

getObjectAccessor

public final ObjectAccessor getObjectAccessor()

Returns:

the object accessor.

createValueNodeMappingsByNodeDescriptorMap

protected Map<D,V> createValueNodeMappingsByNodeDescriptorMap(Collection<V> nodeMappings)

Creates a map of value node mappings by node descriptors.

Parameters:

nodeMappings - the value node mappings for the map values

Returns:

a map of value node mappings by node descriptors
