方法详细资料

close

void close()

指定者:

close 在接口中 java.lang.AutoCloseable

指定者:

close 在接口中 java.io.Closeable

hasNext

boolean hasNext()

指定者:

hasNext 在接口中 java.util.Iterator<TResult>

next

TResult next()

指定者:

next 在接口中 java.util.Iterator<TResult>

tryNext

TResult tryNext()

A special next() case that returns the next element in the iteration if available or null.

Tailable cursors are an example where this is useful. A call to tryNext() may return null, but in the future calling tryNext() would return a new element if a document had been added to the capped collection.

返回:

the next element in the iteration if available or null.
