Method Details

setLoadFilter

public void setLoadFilter(Predicate<T> loadFilter)

Description copied from interface: FilterMethods

Set the load filter. This will be applied whenever loading takes place.

Specified by:

setLoadFilter in interface FilterMethods<T extends StoredObject>

Parameters:

loadFilter - Load filter to be applied while loading.

applyFilterPredicate

public void applyFilterPredicate()

Description copied from interface: FilterMethods

This method is called whenever a filter predicate is changed. Methods with default implementation already invoke this method. If any of those methods are overridden, make sure that it invokes this method so that logic to handle filter changes can be coded here.

Note: This method is used to show the filtered result of the existing entries

Specified by:

applyFilterPredicate in interface FilterMethods<T extends StoredObject>

getLoadFilter

@Nonnull
public ObjectLoadFilter<T> getLoadFilter()

Description copied from interface: FilterMethods

Get the load filter.

Specified by:

getLoadFilter in interface FilterMethods<T extends StoredObject>

Returns:

Current load filter.

getRoots

public List<T> getRoots()

order

public void order(Comparator<? super T> comparator)

Specified by:

order in interface Filtered<T extends StoredObject>

filter

public void filter(Predicate<? super T> filter)

Specified by:

filter in interface Filtered<T extends StoredObject>

filter

public void filter(Predicate<? super T> filter,
 Comparator<? super T> comparator)

Specified by:

filter in interface Filtered<T extends StoredObject>

getFilter

public Predicate<? super T> getFilter()

Specified by:

getFilter in interface Filtered<T extends StoredObject>

getComparator

public Comparator<? super T> getComparator()

Specified by:

getComparator in interface Filtered<T extends StoredObject>

getParent

public final T getParent(T child)

size

public int size()

Description copied from interface: ObjectLoader

Get the instances count.

Specified by:

size in interface Filtered<T extends StoredObject>

Specified by:

size in interface ObjectLoader<T extends StoredObject>

Returns:

Count.

size

public int size(T parent)

size

public int size(int startingIndex,
 int endingIndex)

Specified by:

size in interface Filtered<T extends StoredObject>

size

public int size(T parent,
 int startingIndex,
 int endingIndex)

sizeAll

public int sizeAll()

Specified by:

sizeAll in interface Filtered<T extends StoredObject>

sizeAll

public int sizeAll(T parent)

stream

public Stream<T> stream(int startingIndex,
 int endingIndex)

Specified by:

stream in interface Filtered<T extends StoredObject>

stream

public Stream<T> stream(T parent,
 int startingIndex,
 int endingIndex)

streamAll

public Stream<T> streamAll(int startingIndex,
 int endingIndex)

Specified by:

streamAll in interface Filtered<T extends StoredObject>

streamAll

public Stream<T> streamAll(T parent,
 int startingIndex,
 int endingIndex)

load

public void load(String condition,
 String orderedBy,
 boolean any)

Description copied from interface: ObjectLoader

Load the instances. Current "load filter" if set will be applied. If "master" is already set, "links" of the "master" will be loaded.

Specified by:

load in interface ObjectLoader<T extends StoredObject>

Parameters:

condition - Filtering condition to be applied.

orderedBy - "ORDER BY" clause to use while loading.

any - Whether instanced of the subclasses to be retrieved or not.

load

public void load(int linkType,
 StoredObject master,
 String condition,
 String orderedBy,
 boolean any)

Description copied from interface: ObjectLoader

Load the links of the given "master" instance. Current "load filter" if set will be applied.

Specified by:

load in interface ObjectLoader<T extends StoredObject>

Parameters:

linkType - Link type.

master - Master instance.

condition - Filtering condition to be applied.

orderedBy - "ORDER BY" clause to use while loading.

any - Whether instanced of the subclasses to be retrieved or not.

load

public void load(Iterable<Id> idList)

Description copied from interface: ObjectLoader

Load the instances created from the list of Ids. Current "load filter" if set will be applied. However, ObjectLoader.getOrderBy() result will be ignored. Also, the value returned by ObjectLoader.getAllowAny() will determine whether instanced of the subclasses to be restricted or not.

Specified by:

load in interface ObjectLoader<T extends StoredObject>

Parameters:

idList - List of Ids from which objects to be loaded.

load

Description copied from interface: ObjectLoader

Load the given instances. Current "load filter" if set will be applied. However, ObjectLoader.getOrderBy() result will be ignored. Also, the value returned by ObjectLoader.getAllowAny() will determine whether instanced of the subclasses to be restricted or not.

Specified by:

load in interface ObjectLoader<T extends StoredObject>

Parameters:

objects - Objects to be loaded.

load

public void load(Stream<T> objects)

Description copied from interface: ObjectLoader

Load the given instances. Current "load filter" if set will be applied. However, ObjectLoader.getOrderBy() result will be ignored. Also, the value returned by ObjectLoader.getAllowAny() will determine whether instanced of the subclasses to be restricted or not.

Specified by:

load in interface ObjectLoader<T extends StoredObject>

Parameters:

objects - Objects to be loaded.
