从类复制的说明: AbstractPagedOutputView

This method must return a segment. If no more segments are available, it must throw an EOFException.

指定者:

nextSegment 在类中 AbstractPagedOutputView

参数:

current - The current memory segment

positionInCurrent - The position in the segment, one after the last valid byte.

返回:

The next memory segment.

抛出:

EOFException

getCurrentOffset

public long getCurrentOffset()
