方法详细资料

getTableBuilder

public AsyncTableBuilder<AdvancedScanResultConsumer> getTableBuilder(TableName tableName)

从接口复制的说明: AsyncConnection

Returns an AsyncTableBuilder for creating AsyncTable.

This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.

指定者:

getTableBuilder 在接口中 AsyncConnection

参数:

tableName - the name of the table

getTableBuilder

public AsyncTableBuilder<ScanResultConsumer> getTableBuilder(TableName tableName,
                                                             ExecutorService pool)

从接口复制的说明: AsyncConnection

Returns an AsyncTableBuilder for creating AsyncTable.

This method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.

指定者:

getTableBuilder 在接口中 AsyncConnection

参数:

tableName - the name of the table

pool - the thread pool to use for executing callback

getConfiguration

public org.apache.hadoop.conf.Configuration getConfiguration()

从接口复制的说明: AsyncConnection

Returns the Configuration object used by this instance.

The reference returned is not a copy, so any change made to it will affect this instance.

指定者:

getConfiguration 在接口中 AsyncConnection

close

public void close()

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

getRegionLocator

public AsyncTableRegionLocator getRegionLocator(TableName tableName)

从接口复制的说明: AsyncConnection

Retrieve a AsyncRegionLocator implementation to inspect region information on a table. The returned AsyncRegionLocator is not thread-safe, so a new instance should be created for each using thread. This is a lightweight operation. Pooling or caching of the returned AsyncRegionLocator is neither required nor desired.

指定者:

getRegionLocator 在接口中 AsyncConnection

参数:

tableName - Name of the table who's region is to be examined

返回:

An AsyncRegionLocator instance

getNonceGenerator

public NonceGenerator getNonceGenerator()

getAdminBuilder

public AsyncAdminBuilder getAdminBuilder()

从接口复制的说明: AsyncConnection

Returns an AsyncAdminBuilder for creating AsyncAdmin.

The admin operation's returned CompletableFuture will be finished directly in the rpc framework's callback thread, so typically you should not do any time consuming work inside these methods.

指定者:

getAdminBuilder 在接口中 AsyncConnection

getAdminBuilder

public AsyncAdminBuilder getAdminBuilder(ExecutorService pool)

从接口复制的说明: AsyncConnection

Returns an AsyncAdminBuilder for creating AsyncAdmin.

指定者:

getAdminBuilder 在接口中 AsyncConnection

参数:

pool - the thread pool to use for executing callback

getBufferedMutatorBuilder

public AsyncBufferedMutatorBuilder getBufferedMutatorBuilder(TableName tableName)

从接口复制的说明: AsyncConnection

Returns an AsyncBufferedMutatorBuilder for creating AsyncBufferedMutator.

指定者:

getBufferedMutatorBuilder 在接口中 AsyncConnection

参数:

tableName - the name of the table

getBufferedMutatorBuilder

public AsyncBufferedMutatorBuilder getBufferedMutatorBuilder(TableName tableName,
                                                             ExecutorService pool)

从接口复制的说明: AsyncConnection

Returns an AsyncBufferedMutatorBuilder for creating AsyncBufferedMutator.

指定者:

getBufferedMutatorBuilder 在接口中 AsyncConnection

参数:

tableName - the name of the table

pool - the thread pool to use for executing callback
