Method Detail

generateInvalidPayloadExceptionMessage

public static String generateInvalidPayloadExceptionMessage(byte[] hl7Bytes)

generateInvalidPayloadExceptionMessage

public static String generateInvalidPayloadExceptionMessage(byte[] hl7Bytes,
                                                            int length)

Verifies that the HL7 payload array

The MLLP protocol does not allow embedded START_OF_BLOCK or END_OF_BLOCK characters. The END_OF_DATA character is allowed (and expected) because it is also the segment delimiter for an HL7 message

Parameters:

hl7Bytes - the HL7 payload to validate

Returns:

If the payload is invalid, an error message suitable for inclusion in an exception is returned. If the payload is valid, null is returned;

findFieldSeparatorIndicesInSegment

public static List<Integer> findFieldSeparatorIndicesInSegment(byte[] hl7MessageBytes,
                                                               int startingIndex)

Find the field separator indices in the Segment. NOTE: The last element of the list will be the index of the end of the segment.

Parameters:

hl7MessageBytes - the HL7 binary message

startingIndex - index of the beginning of the HL7 Segment

Returns:

List of the field separator indices, which may be empty.

findMsh18

public static String findMsh18(byte[] hl7Message)

Find the String value of MSH-18 (Character set).

Parameters:

hl7Message - the HL7 binary data to search

Returns:

the String value of MSH-18, or an empty String if not found.

generateAcknowledgementPayload

public static void generateAcknowledgementPayload(MllpSocketBuffer mllpSocketBuffer,
                                                  byte[] hl7MessageBytes,
                                                  String acknowledgementCode)
                                           throws MllpAcknowledgementGenerationException

Throws:

MllpAcknowledgementGenerationException

                                                  String acknowledgementCode,
                                                  String msa3)
                                           throws MllpAcknowledgementGenerationException

Returns:

a String representation of the byte[]

Returns:

bytesToPrintFriendlyStringBuilder
