方法详细资料

initTable

protected void initTable()
                  throws IOException

从类复制的说明: AbstractTableInputFormat

Creates a Scan object and opens the HTable connection to initialize the HBase table.

指定者:

initTable 在类中 AbstractTableInputFormat<org.apache.flink.table.data.RowData>

抛出:

IOException - Thrown, if the connection could not be opened due to an I/O problem.

getScanner

protected org.apache.hadoop.hbase.client.Scan getScanner()

从类复制的说明: AbstractTableInputFormat

Returns an instance of Scan that retrieves the required subset of records from the HBase table.

指定者:

getScanner 在类中 AbstractTableInputFormat<org.apache.flink.table.data.RowData>

返回:

The appropriate instance of Scan for this use case.

getTableName

public String getTableName()

从类复制的说明: AbstractTableInputFormat

What table is to be read.

Per instance of a TableInputFormat derivative only a single table name is possible.

指定者:

getTableName 在类中 AbstractTableInputFormat<org.apache.flink.table.data.RowData>

返回:

The name of the table

mapResultToOutType

protected org.apache.flink.table.data.RowData mapResultToOutType(org.apache.hadoop.hbase.client.Result res)

从类复制的说明: AbstractTableInputFormat

HBase returns an instance of Result.

This method maps the returned Result instance into the output type T.

指定者:

mapResultToOutType 在类中 AbstractTableInputFormat<org.apache.flink.table.data.RowData>

参数:

res - The Result instance from HBase that needs to be converted

返回:

The appropriate instance of T that contains the data of Result.
