Type Parameters:

E - object this reader return

All Implemented Interfaces:

Closeable, Iterator<E>

public class BeanReader<E>
extends Object
implements Iterator<E>, Closeable

Class specialized in reading objects from a file. Used a IReader to read file as iterator of list of Strings. Used a BeanProcessor to transform a list of strings returned by the reader into a new object.

Constructor Detail

BeanReader

public BeanReader(File configFile,
                  IReader reader)
           throws LoadException

Parameters:

configFile - the file which describes how to load the transformer used to transform list of String into new object. Must be not null.

reader - the reader to use. allows to iterate list of Strings from the file the reader deals. Must be not null.

Throws:

LoadException - if an error occurs during loading transformer from file

BeanReader

public BeanReader(File configFile,
                  IReader reader,
                  boolean skipEmptyRow)
           throws LoadException

Parameters:

configFile - the file which describe how to load the transformer used to transform list of String into new object. Must be not null.

reader - the reader to use. allows to iterate list of Strings from the file the reader deals. Must be not null.

skipEmptyRow - avoids reading blank lines and skip creating beans from them

Throws:

LoadException - if an error occurs during loading transformer from file

BeanReader

public BeanReader(IBeanProcessor<E> beanProcessor,
                  IReader reader)

Constructs a BeanReader with a BeanProcessor and a reader.

Parameters:

beanProcessor - the BeanProcessor. Must be not null.

reader - the reader. If this reader products empty row, the Beanreader could return empty bean(use IgnoreNullReader to avoid this case). Must be not null.
