构造器详细资料

ReplaceString

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

方法详细资料

replaceString

public static String replaceString(String originalString,
                                   Pattern pattern,
                                   String replaceByString)

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

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
