Field Detail

conf

protected final ImportConf conf

Deprecated.

Csv import configuration.

model

protected ImportModel<E> model

Deprecated.

Csv import model.

reader

protected com.csvreader.CsvReader reader

Deprecated.

Csv reader (this is the input).

validate

protected Import2(ImportConf conf,
       ImportModel<E> model,
       InputStream inputStream)

Deprecated.

       Reader reader)

Deprecated.

Method Detail

newImport

public static <E> Import2<E> newImport(ImportModel<E> model,
                       InputStream inputStream)

Deprecated.

newImport

public static <E> Import2<E> newImport(ImportModel<E> model,
                       Reader reader)

Deprecated.

                       ImportModel<E> model,
                       Reader reader)

Deprecated.

iterator

public Iterator<ImportRow<E>> iterator()

Deprecated.

Define iterator over import. First of all, the input stream will be validated based on defined model. Iteration will be done on all csv rows except first headers line.

Specified by:

iterator in interface Iterable<ImportRow<E>>

Returns:

the Iterator used for csv iteration

close

public void close()

Deprecated.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

prepareAndValidate

public void prepareAndValidate()

Deprecated.

Read the first mandatory headers line and validate it with the input model. This will check if headers are unique, known by the model and if mandatory headers exist in the file. During this phase, the model will retrieve headers value with ImportModel.pushCsvHeaderNames(List) call.
