方法详细资料

build

public RangeBitmap build(IntFunction<ByteBuffer> supplier)

Converts the appender into an immutable range index.

参数:

supplier - provides an appropriate ByteBuffer to store into

返回:

a queriable RangeBitmap

build

public RangeBitmap build()

see build(IntFunction)

build

public RangeBitmap build(ByteBuffer buffer)

Converts the appender into an immutable range index, using the supplied ByteBuffer.

参数:

buffer - a little endian buffer which must have sufficient capacity for the appended values.

返回:

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.

返回:

the serialized size in bytes.

serialize

public void serialize(ByteBuffer buffer)

Serializes the bitmap to the buffer without materialising it. The user should call serializedSizeInBytes to size the buffer appropriately.

It is not guaranteed that all values will be written

参数:

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.

参数:

value - the value, will be rejected if greater than max value.
