Method Detail

setMandatoryHeaders

public void setMandatoryHeaders(java.lang.String[] mandatoryHeaders)

Sets mandatory headers - if they are not found, NoDataException is thrown.

Parameters:

mandatoryHeaders - the headers that must exist in first row

setDataTextObjectWithDelimiter

protected void setDataTextObjectWithDelimiter(DataTextObjectWithDelimiter inp)

Sets the file containing the rows to be imported.

Parameters:

inp - the file containing the rows to be imported

setMainDataObject

protected void setMainDataObject(DataObject mainDataObject)

Set the main DataObject receiving the imported rows.

Parameters:

mainDataObject - main DataObject receiving the imported rows

addDescDo

protected <DoByDesc extends DataObject & LoadableByDescription> void addDescDo(DoByDesc descDo)

Adds a DataObject implementing LoadableByDescription to delegate import to a table reference. Preferred version: full automatic - causes a new entry in the reference DataObject if not found + assigns the internal value to the main data object.

Parameters:

descDo - DataObject implementing LoadableByDescription

addDescDo

protected <DoByDesc extends DataObject & LoadableByDescription> void addDescDo(java.lang.String desc,
                                                                               DoByDesc descDo)

Adds a DataObject implementing LoadableByDescription to delegate import to a table reference. Preferred version: full automatic - causes a new entry in the reference DataObject if not found + assigns the internal value to the main data object.

Parameters:

desc - the description of the column

descDo - DataObject implementing LoadableByDescription

addRefDo

protected void addRefDo(java.lang.String keyColumn,
                        DataObject refDo)

Adds a reference DataObject with single string identifier associated with the column. Causes a new entry in the reference DataObject if not found. Elder version - half automatic - prefer using addDescDo!

Parameters:

keyColumn - the key column name

refDo - the reference data object

importFromTextFile

public void importFromTextFile(java.lang.String filePath)
                        throws ImportStd.NoDataFoundException

Throws:

ImportStd.NoDataFoundException

processImport

protected void processImport()
                      throws ImportStd.NoDataFoundException

Throws:

ImportStd.NoDataFoundException

setInitialValues

protected void setInitialValues()

beforeSaving

protected void beforeSaving()

load

protected boolean load()

Returns true if a database record exists which matches the row to import. Override it to use this feature.

Returns:

true if a database record exists which matches the row to import

getImportAmount

public int getImportAmount()
