Method Detail

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

Returns:

The WriteEntry of the current entry

disposeInternal

protected final void disposeInternal(long handle)

Specified by:

disposeInternal in class RocksObject

close

public void close()

Description copied from class: 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 disposed, calling any of its functions will lead to undefined behavior.

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class AbstractImmutableNativeReference
