Class ExtendedMinLowerLayerProtocol

java.lang.Object
  ca.uhn.hl7v2.llp.LowerLayerProtocol
      ca.uhn.hl7v2.llp.ExtendedMinLowerLayerProtocol

public class ExtendedMinLowerLayerProtocol
extends LowerLayerProtocol

Minimal Lower Layer Protocol implementation which is detects the text character set being used by reading in the MSH-18 value. For example, if MSH-18 contains "ISO-8859-1", the message is parsed using 8859/1 charset encoding. If MSH-18 contains "UNICODE UTF-8", the message is parsed using UTF-8 charset encoding.

Please note the following warnings regarding the use of this class:

• At present, this class supports only the ER7 (pipe and hat) message style. Using it to receive an XML style message will result in undefined behaviour.
• This class attempts to detect UTF-16 encoding by searching for a byte order mark at the beginning of the string. While the BOM is optional in UTF-16 encoding, this class will not correctly detect UTF-16 if it is missing. Both big-endian and little-endian byte order is supported for UTF-16.
