getSortedTvListForQuery

public TVList getSortedTvListForQuery()

从接口复制的说明: IWritableMemChunk

served for query requests.

if tv list has been sorted, just return reference of it

if tv list hasn't been sorted and has no reference, sort and return reference of it

if tv list hasn't been sorted and has reference we should copy and sort it, then return ths list

the mechanism is just like copy on write

This interface should be synchronized for concurrent with sortTvListForFlush

指定者:

getSortedTvListForQuery 在接口中 IWritableMemChunk

返回:

sorted tv list

getSortedTvListForQuery

public TVList getSortedTvListForQuery(List<IMeasurementSchema> schemaList)

served for vector query requests.

the mechanism is just like copy on write

指定者:

getSortedTvListForQuery 在接口中 IWritableMemChunk

返回:

sorted tv list

sortTvListForFlush
