Method Details

retrieveNativeKeys

public ISMObject[] retrieveNativeKeys()

Description copied from class: SQLWrapper

Native Keys refer to either a. any keys set by setRecordKey b. in absence of any keys defined by setRecordKey, then an additional index keys is created by SoftwareMining framework. (This is usually called INDX_FLD_0;)

Specified by:

retrieveNativeKeys in interface ISQLWrapper

Overrides:

retrieveNativeKeys in class SQLWrapper

Returns:

addRecordKeyField

public void addRecordKeyField(AbstractCBLField field)

priorRecord

public void priorRecord()

first

public void first()

firstRecord

public void firstRecord()
                 throws IOCriticalException

Specified by:

firstRecord in interface IDb400

Throws:

IOCriticalException

last

public void last()

lastRecord

public void lastRecord()
                throws IOCriticalException

Specified by:

lastRecord in interface IDb400

Throws:

IOCriticalException

assignLegacyFileNames

protected void assignLegacyFileNames(String[] legacyFileNames)

This is for benefit of CL. Before running the program, the CL can tell the system to swap one file-name with another (from this list). Note the fileNames would have referred to table-names or VIEWS-names. I.e the system wants to replace a TABLE/VIEW-NAME (from this list) with another TABLE/VIEW-NAME - without specifying which DB400 class actually references it. Therefore this class provides a means for identifying which Db400 class was referencing the original Table/View name.

Parameters:

fileNames -

referencesLegacyFile

public boolean referencesLegacyFile(String fileName)

Parameters:
