构造器详细资料

DimensionLookup

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

方法详细资料

setMeta

protected void setMeta(DimensionLookupMeta meta)

setData

protected void setData(DimensionLookupData data)

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

isAutoIncrement

protected boolean isAutoIncrement()

dimInsert

public Long dimInsert(org.pentaho.di.core.row.RowMetaInterface inputRowMeta,
                      Object[] row,
                      Long technicalKey,
                      boolean newEntry,
                      Long versionNr,
                      Date dateFrom,
                      Date dateTo)
               throws org.pentaho.di.core.exception.KettleException

This inserts new record into dimension Optionally, if the entry already exists, update date range from previous version of the entry.

抛出:

org.pentaho.di.core.exception.KettleException

isRowLevel

public boolean isRowLevel()

从类复制的说明: BaseStep

Checks if is row level.

覆盖:

isRowLevel 在类中 BaseStep

返回:

true, if is row level

isDebug

public boolean isDebug()

从类复制的说明: BaseStep

Checks if is debug.

覆盖:

isDebug 在类中 BaseStep

返回:

true, if is debug

dimUpdate
