Constructor Detail

AbstractReader

public AbstractReader(Reader r)

Constructs a reader to read messages from a given Reader instance

AbstractReader

public AbstractReader(String string)

Constructs a reader to read messages from a string

Throws:

IllegalArgumentException - if string is null

AbstractReader

public AbstractReader(InputStream stream)

Constructs a reader to read messages from a stream

Throws:

IllegalArgumentException - if stream is null

Throws:

IllegalArgumentException - if file is null

FileNotFoundException

Method Detail

iterator

public Iterator<String> iterator()

Specified by:

iterator in interface Iterable<String>

next

public abstract String next()

Specified by:

next in interface Iterator<String>

remove

public void remove()

Specified by:

remove in interface Iterator<String>

nextMT

public AbstractMT nextMT()
                  throws IOException

Reads the next raw content from the iterator and returns the message parsed into an MT.

IMPORTANT:
Since MTnnn model classes are implemented only for system and user-to-user messages (categories 0 to 9) if an ACK/NAK (service id 21) message is found, the MT following the system message is returned (not the ACK/NAK).
For other service messages (login, select, quit) this method will return null because there is no MT representation to create.
If you need to deal with all type of messages (including service, system and user-to-user) you can use nextSwiftMessage() instead.

Returns:

parsed message or null if content is blank

Throws:

IOException - if the message content cannot be parsed into an MT

nextSwiftMessage

public SwiftMessage nextSwiftMessage()
                              throws IOException

Reads the next raw content from the iterator and returns the message parsed as a generic SwiftMessage. This method is convenient where the RJE content can include any type of message including service messages, system messages and user-to-user messages.

Returns:

parsed message or null if content is blank

Throws:

IOException - if the message content cannot be parsed into a SwiftMessage
