Method Detail
-
build
public RangeBitmap build(java.util.function.IntFunction<java.nio.ByteBuffer> supplier)
Converts the appender into an immutable range index.- Parameters:
supplier
- provides an appropriate ByteBuffer to store into- Returns:
- a queriable RangeBitmap
-
build
public RangeBitmap build()
{@see #build(IntFunction)}
-
build
public RangeBitmap build(java.nio.ByteBuffer buffer)
Converts the appender into an immutable range index, using the supplied ByteBuffer.- Parameters:
buffer
- a little endian buffer which must have sufficient capacity for the appended values.- Returns:
- a queriable RangeBitmap
-
clear
public void clear()
Call this to reuse the appender and its buffers
-
serializedSizeInBytes
public int serializedSizeInBytes()
Returns the size of the RangeBitmap on disk.- Returns:
- the serialized size in bytes.
-
serialize
public void serialize(java.nio.ByteBuffer buffer)
Serializes the bitmap to the buffer without materialising it. The user should call {@see serializedSizeInBytes} to size the buffer appropriately.It is not guaranteed that all values will be written
- Parameters:
buffer
- expected to be large enough to contain the bitmap.
-
add
public void add(long value)
Adds the value and associates it with the current row index.- Parameters:
value
- the value, will be rejected if greater than max value.
