Constructor Detail

BeanList

public BeanList(List<E> list)

Specify the underlying List implementation.

BeanList

public BeanList()

Uses an ArrayList as the underlying List implementation.

BeanList

public BeanList(BeanCollectionLoader loader,
                Object ownerBean,
                String propertyName)

Used to create deferred fetch proxy.

Method Detail

addBean

public void addBean(Object bean)

Description copied from interface: BeanCollectionAdd

Add a loaded bean to the collection.

Specified by:

addBean in interface BeanCollectionAdd

internalAdd

public void internalAdd(Object bean)

Description copied from interface: BeanCollection

Add the bean to the collection.

This is disallowed for BeanMap.

Specified by:

internalAdd in interface BeanCollection<E>

checkEmptyLazyLoad

public boolean checkEmptyLazyLoad()

Description copied from interface: BeanCollection

Check after the lazy load that the underlying collection is not null (handle case where join to many not outer).

That is, if the collection was not loaded due to filterMany predicates etc then make sure the collection is set to empty.

Specified by:

checkEmptyLazyLoad in interface BeanCollection<E>

setActualList

public void setActualList(List<?> list)

Set the actual underlying list.

This is primarily for the deferred fetching function.

getActualList

public List<E> getActualList()

Return the actual underlying list.

getActualDetails

public Collection<E> getActualDetails()

Description copied from interface: BeanCollection

Returns the underlying details as an iterator.

Note that for maps this returns the entrySet as we need the keys of the map.

Specified by:

getActualDetails in interface BeanCollection<E>

getActualCollection

public Object getActualCollection()

Returns the underlying list.

Specified by:

getActualCollection in interface BeanCollection<E>

isPopulated

public boolean isPopulated()

Return true if the underlying list is populated.

Specified by:

isPopulated in interface BeanCollection<E>

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Equal if obj is a List and equal in a list sense.

Specifically obj does not need to be a BeanList but any list. This does not use the FindMany, fetchedMaxRows or finishedFetch properties in the equals test.

Specified by:

equals in interface Collection<E>

Specified by:

equals in interface List<E>

Overrides:

equals in class Object

hashCode

public int hashCode()

Specified by:

hashCode in interface Collection<E>

Specified by:

hashCode in interface List<E>

Overrides:

hashCode in class Object

add

public void add(int index,
                E element)

Specified by:

add in interface List<E>

add

public boolean add(E o)

Specified by:

add in interface Collection<E>

Specified by:

add in interface List<E>

addAll

public boolean addAll(Collection<? extends E> c)

Specified by:

addAll in interface Collection<E>

Specified by:

addAll in interface List<E>

addAll

public boolean addAll(int index,
                      Collection<? extends E> c)

Specified by:
