setLookahead

public SkipListMemTableConfig setLookahead(long lookahead)

返回:

the current instance of SkipListMemTableConfig

lookahead

public long lookahead()

Returns the currently set lookahead value.

返回:

lookahead value

newMemTableFactoryHandle

从类复制的说明: MemTableConfig

This function should only be called by Options.setMemTableConfig(), which will create a c++ shared-pointer to the c++ MemTableRepFactory that associated with the Java MemTableConfig.

指定者:

newMemTableFactoryHandle 在类中 MemTableConfig

返回:

native handle address to native memory table instance.
