                                                long hotTtl)

Creates an object to access a HBase table. Used by HBase internally. DO NOT USE. See ConnectionFactory class comment for how to get a Table instance (use Table instead of LayeredHTable).

参数:

connection - Connection to be used.

builder - The table builder

rpcCallerFactory - The RPC caller factory

rpcControllerFactory - The RPC controller factory

pool - ExecutorService to be used.

方法详细资料

getScanner

public ResultScanner getScanner(Scan scan)
                         throws IOException

The underlying LayeredHTable must not be closed. Table.getScanner(Scan) has other usage details.

指定者:

getScanner 在接口中 Table

覆盖:

getScanner 在类中 HTable

参数:

scan - A configured Scan object.

返回:

A scanner.

抛出:

IOException - if a remote or network exception occurs.

get

protected Result get(Get get,
                     boolean checkExistenceOnly)
              throws IOException

覆盖:

get 在类中 HTable

抛出:

IOException

get

public Result[] get(List<Get> gets)
             throws IOException

从接口复制的说明: Table

Extracts specified cells from the given rows, as a batch.

指定者:

get 在接口中 Table

覆盖:

get 在类中 HTable

参数:

gets - The objects that specify what data to fetch and from which rows.

返回:

The data coming from the specified rows, if it exists. If the row specified doesn't exist, the Result instance returned won't contain any Cells, as indicated by Result.isEmpty(). If there are any failures even after retries, there will be a null in the results' array for those Gets, AND an exception will be thrown. The ordering of the Result array corresponds to the order of the list of passed in Gets.

抛出:

IOException - if a remote or network exception occurs.
