public class ContainerAppender<C extends WordStorage<C>,T extends BitmapDataProvider & AppendableStorage<C>> extends java.lang.Object implements RoaringBitmapWriter<T>
This class can be used to write quickly values to a bitmap. The values are expected to be (increasing) sorted order. Values are first written to a temporary internal buffer, but the underlying bitmap can forcefully synchronize by calling "flush" (although calling flush to often would defeat the performance purpose of this class). The main use case for an ContainerAppender is to get bitmaps quickly. You should benchmark your particular use case to see if it helps.//... RoaringBitmapWriter<RoaringBitmap> writer = RoaringBitmapWriter.writer().get(); for (int i :....) { writer.add(i); } writer.flush(); // important

Method Detail
-
getUnderlying
public T getUnderlying()
Grab a reference to the underlying bitmap- Specified by:
getUnderlying
in interfaceRoaringBitmapWriter<C extends WordStorage<C>>
- Returns:
- the underlying bitmap
-
add
public void add(int value)
Adds the value to the underlying bitmap. The data might be added to a temporary buffer. You should call "flush" when you are done.- Specified by:
add
in interfaceRoaringBitmapWriter<C extends WordStorage<C>>
- Parameters:
value
- the value to add.
-
add
public void add(long min, long max)
Description copied from interface:RoaringBitmapWriter
Add a range to the bitmap- Specified by:
add
in interfaceRoaringBitmapWriter<C extends WordStorage<C>>
- Parameters:
min
- the inclusive min valuemax
- the exclusive max value
-
addMany
public void addMany(int... values)
Description copied from interface:RoaringBitmapWriter
Adds many values to the bitmap.- Specified by:
addMany
in interfaceRoaringBitmapWriter<C extends WordStorage<C>>
- Parameters:

- the values to add
-
flush
public void flush()
Ensures that any buffered additions are flushed to the underlying bitmap.- Specified by:
flush
in interfaceRoaringBitmapWriter<C extends WordStorage<C>>
-
reset
public void reset()
Description copied from interface:RoaringBitmapWriter
