Constructor Detail

ItemProcessor

protected ItemProcessor(ItemTO<?> entry)

Protected constructor used by EntryProcessor.getInstance(net.sf.layoutParser.to.EntryTO)

Parameters:

entry - The object containing all information regarding the ItemTO that is going to be used to parse or format data.

Method Detail

format

public String format(Object field)
              throws MalformedOutputException

Formats the field using EntryProcessor.entry information.
The job of formating is done by calling TypeHandler#format(data, format, filler, size), so in order
to format a ItemTO, the EntryTO.getType() should have a TypeHandler that handles this kind of "type".

After the format, the string is validated using ItemTO.getMaskName() to retrieve a MaskTO and
check the string data against the regex in MaskTO.

Specified by:

format in class EntryProcessor<ItemTO<?>>

Parameters:

field - The object that should be parsed

Returns:

The block of positional data representing the field

Throws:

MalformedOutputException - In case there's a problem formating the field into a positional data string

EntryProcessor.format(java.lang.Object), TypeHandler.format(Object, String, String, int)

parse

public Object parse(String data)
             throws MalformedInputException

Parses the field using EntryProcessor.entry information.
First and foremost the data passed to the method is going to be validated against the mask informed on ItemTO.getMaskName(). The job of parsing is done by calling TypeHandler#parse(data, format), so in order
to parse a ItemTO, the EntryTO.getType() should have a TypeHandler that handles this kind of "type".

Specified by:

parse in class EntryProcessor<ItemTO<?>>

Parameters:

data - Textual raw data to be parsed.

Returns:

A object that represents the EntryTO.getType().

Throws:

MalformedInputException - In case there's a problem parsing the data.
