方法详细资料

entry

public WBWIRocksIterator.WriteEntry entry()

Get the current entry

The WriteEntry is only valid until the iterator is repositioned. If you want to keep the WriteEntry across iterator movements, you must make a copy of its data!

Note - This method is not thread-safe with respect to the WriteEntry as it performs a non-atomic update across the fields of the WriteEntry

返回:

The WriteEntry of the current entry

disposeInternal

protected final void disposeInternal(long handle)

指定者:

disposeInternal 在类中 RocksObject

close

public void close()

从类复制的说明: AbstractNativeReference

Frees the underlying C++ object

It is strong recommended that the developer calls this after they have finished using the object.

Note, that once an instance of AbstractNativeReference has been closed, calling any of its functions will lead to undefined behavior.

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 AbstractImmutableNativeReference
