构造器详细资料

BaseRowProcessor

public BaseRowProcessor()

方法详细资料

preProcess

public void preProcess(HRegion region,
                       WALEdit walEdit)
                throws IOException

从接口复制的说明: RowProcessor

The hook to be executed before process().

指定者:

preProcess 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

参数:

region - the HRegion

walEdit - the output WAL edits to apply to write ahead log

抛出:

IOException

preBatchMutate

public void preBatchMutate(HRegion region,
                           WALEdit walEdit)
                    throws IOException

从接口复制的说明: RowProcessor

The hook to be executed after the process() but before applying the Mutations to region. Also by the time this hook is called, mvcc transaction have started.

指定者:

preBatchMutate 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

walEdit - the output WAL edits to apply to write ahead log

抛出:

IOException

postBatchMutate

public void postBatchMutate(HRegion region)
                     throws IOException

从接口复制的说明: RowProcessor

The hook to be executed after the process() and applying the Mutations to region. The difference of this one with RowProcessor.postProcess(HRegion, WALEdit, boolean) is this hook will be executed before the mvcc transaction completion.

指定者:

postBatchMutate 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

抛出:

IOException

postProcess

public void postProcess(HRegion region,
                        WALEdit walEdit,
                        boolean success)
                 throws IOException

从接口复制的说明: RowProcessor

The hook to be executed after process() and applying the Mutations to region.

指定者:

postProcess 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

参数:

region - the HRegion

walEdit - the output WAL edits to apply to write ahead log

success - true if batch operation is successful otherwise false.

抛出:

IOException

getClusterIds

public List<UUID> getClusterIds()

指定者:

getClusterIds 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

返回:

The cluster ids that have the change.

getName

public String getName()

从接口复制的说明: RowProcessor

Human readable name of the processor

指定者:

getName 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

返回:

The name of the processor

useDurability

public Durability useDurability()

指定者:

useDurability 在接口中 RowProcessor<S extends com.google.protobuf.Message,T extends com.google.protobuf.Message>

返回:

The Durability to use
