Package com.e1c.langtool.generatestring

Class TempFileFeatureCollection

java.lang.Object

com.e1c.langtool.generatestring.TempFileFeatureCollection

All Implemented Interfaces:

Iterable<FeatureValue>, Collection<FeatureValue>

public class TempFileFeatureCollection
extends Object
implements Collection<FeatureValue>

Temp file storage for collection of FeatureValue, using MapDB. It is necessary to use temp storage while collecting huge number of objects, such as "all object of a project". This collection allows to store fast in memory small amount of data with evicting this data to temp-file storage.

Constructor Details

TempFileFeatureCollection

public TempFileFeatureCollection()

Instantiates a new temp-file feature collection.

Method Details

dispose

public void dispose()

finalize

@Deprecated
protected void finalize()
                 throws Throwable

Deprecated.

Overrides:

finalize in class Object

Throws:

Throwable

size

public int size()

Specified by:

size in interface Collection<FeatureValue>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<FeatureValue>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<FeatureValue>

resourceIterator

public Iterator<Long> resourceIterator()

The iterator of TOP-object resources.

Returns:

the iterator, cannot be null.

• #getResourceBucket(Long)
• #putResourceBucket(Long, Collection)

iterator

public Iterator<FeatureValue> iterator()

Specified by:

iterator in interface Collection<FeatureValue>

Specified by:

iterator in interface Iterable<FeatureValue>

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<FeatureValue>

toArray

public <T> T[] toArray(T[] a)

Specified by:

toArray in interface Collection<FeatureValue>

add

public boolean add(FeatureValue e)

Specified by:

add in interface Collection<FeatureValue>

remove

public boolean remove(Object o)

Specified by:

remove in interface Collection<FeatureValue>

updateValue

public void updateValue(FeatureValue value)

Update given value in the MapDB. MapDB expect keys and values to be immutable. If we violate this assertion we should explicitly update value in the map.

Parameters:

value - Value to be updated, cannot be null.

containsAll

public boolean containsAll(Collection<?> c)

Specified by:

containsAll in interface Collection<FeatureValue>

addAll

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

Specified by:

addAll in interface Collection<FeatureValue>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<FeatureValue>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<FeatureValue>

clear

public void clear()

Specified by:

clear in interface Collection<FeatureValue>

getResourceBucket

public Collection<FeatureValue> getResourceBucket(long id)

Gets the resource bucket of collected FeatureValue. Warning! Callers should not modify this resource collection itself. Otherwise should call add(FeatureValue) and remove(Object).

Parameters:

id - the id of resource, that gets from resourceIterator()

Returns:

the resource bucket

putResourceBucket

public void putResourceBucket(long id,
 Collection<FeatureValue> bucket)

Put resource bucket back to cache.

Parameters:

id - the id of the resource, cannot be {@link null}

bucket - the bucket of collected features from the resource, cannot be {@link null}
