类 AbstractCompactionFilterFactory<T extends AbstractCompactionFilter<?>>

java.lang.Object

org.rocksdb.AbstractNativeReference

org.rocksdb.AbstractImmutableNativeReference

org.rocksdb.RocksCallbackObject

org.rocksdb.AbstractCompactionFilterFactory<T>

类型参数:

T - The concrete type of the compaction filter

所有已实现的接口:

java.lang.AutoCloseable

public abstract class AbstractCompactionFilterFactory<T extends AbstractCompactionFilter<?>>
extends RocksCallbackObject

Each compaction will create a new AbstractCompactionFilter allowing the application to know about different compactions

方法详细资料

initializeNative

protected long initializeNative(long... nativeParameterHandles)

从类复制的说明: RocksCallbackObject

Construct the Native C++ object which will callback to our object methods

指定者:

initializeNative 在类中 RocksCallbackObject

参数:

nativeParameterHandles - An array of native handles for any parameter objects that are needed during construction

返回:

The native handle of the C++ object which will callback to us

createCompactionFilter

public abstract T createCompactionFilter(AbstractCompactionFilter.Context context)

Create a new compaction filter

参数:

context - The context describing the need for a new compaction filter

返回:

A new instance of AbstractCompactionFilter

name

public abstract java.lang.String name()

A name which identifies this compaction filter

The name will be printed to the LOG file on start up for diagnosis

返回:

name which identifies this compaction filter.

disposeInternal

protected void disposeInternal()

We override RocksCallbackObject.disposeInternal() as disposing of a rocksdb::AbstractCompactionFilterFactory requires a slightly different approach as it is a std::shared_ptr

覆盖:

disposeInternal 在类中 RocksCallbackObject
