DynamicSQLRow

public DynamicSQLRow(StepMeta stepMeta,
                     StepDataInterface stepDataInterface,
                     int copyNr,
                     TransMeta transMeta,
                     Trans trans)

方法详细资料

processRow

public boolean processRow(StepMetaInterface smi,
                          StepDataInterface sdi)
                   throws org.pentaho.di.core.exception.KettleException

从接口复制的说明: StepInterface

Perform the equivalent of processing one row. Typically this means reading a row from input (getRow()) and passing a row to output (putRow)).

指定者:

processRow 在接口中 StepInterface

覆盖:

processRow 在类中 BaseStep

参数:

smi - The steps metadata to work with

sdi - The steps temporary working data to work with (database connections, result sets, caches, temporary variables, etc.)

返回:

false if no more rows can be processed or an error occurred.

抛出:

org.pentaho.di.core.exception.KettleException

stopRunning

public void stopRunning(StepMetaInterface smi,
                        StepDataInterface sdi)
                 throws org.pentaho.di.core.exception.KettleException

Stop the running query

指定者:

stopRunning 在接口中 StepInterface

覆盖:

stopRunning 在类中 BaseStep

参数:

smi - The metadata that might be needed by the step to stop running.

sdi - The interface to the step data containing the connections, resultsets, open files, etc.

抛出:

org.pentaho.di.core.exception.KettleException - in case something goes wrong

init

public boolean init(StepMetaInterface smi,
                    StepDataInterface sdi)

从接口复制的说明: StepInterface

Initialize and do work where other steps need to wait for...

指定者:

init 在接口中 StepInterface

覆盖:

init 在类中 BaseStep

参数:

smi - The metadata to work with

sdi - The data to initialize

dispose

public void dispose(StepMetaInterface smi,
                    StepDataInterface sdi)

从接口复制的说明: StepInterface

Dispose of this step: close files, empty logs, etc.

指定者:

dispose 在接口中 StepInterface

覆盖:

dispose 在类中 BaseStep

参数:

smi - The metadata to work with

sdi - The data to dispose of
