示例1: release
import org.apache.flink.core.memory.MemorySegment; //导入方法依赖的package包/类
/**
* Tries to release the memory for the specified segment. If the segment has already been released or
* is null, the request is simply ignored.
*
* <p>If the memory manager manages pre-allocated memory, the memory segment goes back to the memory pool.
* Otherwise, the segment is only freed and made eligible for reclamation by the GC.
*
* @param segment The segment to be released.
* @throws IllegalArgumentException Thrown, if the given segment is of an incompatible type.
