Method Details

typeSupported

public static boolean typeSupported(Object body)

Determines whether the given object belongs to the predefined set of supported data types.

Parameters:

body - The object to check.

Returns:

true when the type of the object is supported by the HL7v2 adapter out-of-the-box, false otherwise.

convertBodyToString

public static String convertBodyToString(Message message,
 String charsetName,
 boolean defragmentSegments)
                                  throws Exception

Converts message contents to a String using the given character set (statically or in MSH-18) and replaces all '\n''s with '\r''s.

If requested, segments will be defragmented as well.

Parameters:

message - Camel message

charsetName - charset name

Returns:

string

Throws:

Exception

convertMessageToByteArray

public static byte[] convertMessageToByteArray(Message message,
 String charsetName)
                                        throws Exception

Converts Camel message to a Byte Array using the given character set (statically or in MSH-18). This is necessary before a HL7 message object or string is remotely transferred to have full control over the encoding.

Parameters:

message - Camel message

charsetName - charset name

Returns:

byte array

Throws:

Exception

convertBodyToByteArray

public static byte[] convertBodyToByteArray(Object body,
 String charsetName)
                                     throws Exception

Converts HL7 object to a Byte Array using the given character set (statically or in MSH-18). This is necessary before a HL7 message object or string is remotely transferred to have full control over the encoding.

Parameters:

body - HL7 object

charsetName - charset name

Returns:

byte array

Throws:

Exception

convertBodyToMessage

public static Message convertBodyToMessage(Message message,
 String defaultCharsetName,
 Parser parser)
                                    throws Exception

Converts the contents of the given Camel message to a Message. This is necessary when either a transferred HL7 message is unmarshalled or we need to access message details for further processing in interceptors.

Parameters:

message - Camel message to be converted.

defaultCharsetName - default character set.

parser - HL7 parser.

Returns:

a Message or null when it was impossible to get or create one.

Throws:

Exception
