Interface RecordParserFactory

All Known Implementing Classes:

CsvRecordParserFactory, DelimitedRecordParserFactory, FixedLengthRecordParserFactory, JsonRecordParserFactory, RecordParserFactorySupport, XmlRecordParserFactory

public interface RecordParserFactory

Factory interface for creating record parsers.

The Java object bound to a record depends on the stream format. The following table shows the object used for each format:

Format	Record Type
Fixed Length	String
CSV, Delimited	String[]
XML	Document

The following table shows the method invoked for a requested BeanIO interface.

Requests For	Invokes
BeanReader	createReader(Reader)
BeanWriter	createWriter(Writer)
Unmarshaller	createUnmarshaller()
Marshaller	createMarshaller()

A RecordParserFactory implementation must be thread safe (after all of its properties have been set).

Since:

2.0

Method Summary

Modifier and Type	Method and Description
RecordMarshaller	createMarshaller() Creates a parser for marshalling records.
RecordReader	createReader(Reader in) Creates a parser for reading records from an input stream.
RecordUnmarshaller	createUnmarshaller() Creates a parser for unmarshalling records.
RecordWriter	createWriter(Writer out) Creates a parser for writing records to an output stream.
void	init() Initializes the factory.

Method Detail

init

void init()
   throws IllegalArgumentException

Initializes the factory. This method is called when a mapping file is loaded after all parser properties have been set, and is therefore ideally used to preemptively validate parser configuration settings.

Throws:

IllegalArgumentException - if the parser configuration is invalid

createReader

RecordReader createReader(Reader in)
                   throws IllegalArgumentException

Creates a parser for reading records from an input stream.

Parameters:

in - the input stream to read from

Returns:

the created RecordReader

Throws:

IllegalArgumentException - if this factory is improperly configured and a RecordReader cannot be created

createWriter

RecordWriter createWriter(Writer out)
                   throws IllegalArgumentException

Creates a parser for writing records to an output stream.

Parameters:

out - the output stream to write to

Returns:

the new RecordWriter

Throws:

IllegalArgumentException - if this factory is improperly configured and a RecordWriter cannot be created

createMarshaller

RecordMarshaller createMarshaller()
                           throws IllegalArgumentException

Creates a parser for marshalling records.

Returns:

the created RecordMarshaller

Throws:

IllegalArgumentException - if this factory is improperly configured and a RecordMarshaller cannot be created

createUnmarshaller

RecordUnmarshaller createUnmarshaller()
                               throws IllegalArgumentException

Creates a parser for unmarshalling records.

Returns:

the created RecordUnmarshaller

Throws:

IllegalArgumentException - if this factory is improperly configured and a RecordUnmarshaller cannot be created
