Constructor Detail

TableAgileMart

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

Method Detail

init

public boolean init(StepMetaInterface smi,
                    StepDataInterface sdi)

Description copied from interface: StepInterface

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

Specified by:

init in interface StepInterface

Overrides:

init in class TableOutput

Parameters:

smi - The metadata to work with

sdi - The data to initialize

adjustSchema

public boolean adjustSchema()

Description copied from interface: TableManager

Adjust schema. This is used to change the schema when the input fields change.

Specified by:

adjustSchema in interface TableManager

Returns:

true if the operation succeeded

writeToTable

protected Object[] writeToTable(org.pentaho.di.core.row.RowMetaInterface rowMeta,
                                Object[] r)
                         throws org.pentaho.di.core.exception.KettleException

Overrides:

writeToTable in class TableOutput

Throws:

org.pentaho.di.core.exception.KettleException

flush

public boolean flush()

Description copied from interface: TableManager

Flushes the current in-memory buffer to the storage system. This is called during cancel operations when the current set of data is still wanted.

Specified by:

flush in interface TableManager

Returns:

true if the operation succeeded

processRow

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

Description copied from interface: StepInterface

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

Specified by:

processRow in interface StepInterface

Overrides:

processRow in class TableOutput

Parameters:

smi - The steps metadata to work with

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

Returns:

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

Throws:

org.pentaho.di.core.exception.KettleException

dropTable

public boolean dropTable()

Description copied from interface: TableManager

Drops the current table. This is used during management operations.

Specified by:

dropTable in interface TableManager

Returns:

true if the operation succeeded

getMessage

public String getMessage()

Description copied from interface: TableManager

Returns a human-readable message about any errors that have occurred. If any of the operations (dropTable, flush, truncateTable) fail, this method should return a nice, accurate message describing the problem that was encountered.

Specified by:

getMessage in interface TableManager

Returns:

setRowLimit

public void setRowLimit(long rowLimit)

Description copied from interface: TableManager

Sets the row limit. This is used to limit the data loaded during a specific execution. This value might change every time the transformation is executed.

Specified by:

setRowLimit in interface TableManager

setTableName

public void setTableName(String tableName)

Description copied from interface: TableManager

Sets the table name. If the name of the database table is determined programatically this method can be used to set the table name.

Specified by:

setTableName in interface TableManager

truncateTable

public boolean truncateTable()

Description copied from interface: TableManager

Truncates the current table. This is used during management operations.

Specified by:

truncateTable in interface TableManager

Returns:

true if the operation succeeded
