Method Detail

clear

protected abstract void clear(C target)

Calls the clear method on the target collection

Parameters:

target - the collection to call clear() on

create

protected abstract C create()

Creates a new instance of the collection class

Returns:

mapItem

public Object mapItem(BeanMapper beanMapper,
                      Class collectionElementClass,
                      Object source)

getTargetCollection

public C getTargetCollection(BeanCollectionUsage collectionUsage,
                             Class<C> preferredCollectionClass,
                             Class<?> collectionElementClass,
                             C targetCollection,
                             CollectionFlusher collectionFlusher,
                             Boolean mustFlush)

Description copied from interface: CollectionHandler

Retrieves either the target collection or creates a new collection instance. If CONSTRUCT is set, it will always create a new instance. For the other two options a new instance will only be created if the target collection is null. If CLEAR is used, the target collection will have its clear() method called.

Specified by:

getTargetCollection in interface CollectionHandler<C>

Parameters:

collectionUsage - the type of collection usage to apply

preferredCollectionClass - the class type of the target collection

collectionElementClass - the class type of an element within the target collection

targetCollection - the actual target collection

collectionFlusher - the flusher to call after clear has been called on a filled collection

mustFlush - whether flush must be called after clear on a collection has been called

Returns:

the target collection to copy the source collection to

getType

public Class<C> getType()

Description copied from interface: CollectionHandler

The type of the collection class. This will be used to determine if the source collection contains the type somewhere in its super classes or interfaces

Specified by:

getType in interface CollectionHandler<C>

Returns:

the type of the collection class

isMatch

public boolean isMatch(Class<?> clazz)

Description copied from interface: CollectionHandler

Check if the sourceClass contains the matching class somewhere in its hierarchy

Specified by:

isMatch in interface CollectionHandler<C>

Parameters:

clazz - the class to check for the type

Returns:

true if the class can be upcast to the type

create

protected C create(Class<?> elementClass)

determineGenericParameterFromType

public Class<?> determineGenericParameterFromType(ParameterizedType type)

Specified by:

determineGenericParameterFromType in interface CollectionHandler<C>

getGenericParameterIndex

protected int getGenericParameterIndex()
