NAME

6       Net::HL7::Segments::MSH
7

SYNOPSIS

9       my $seg = new Net::HL7::Segments::MSH();
10
11       $seg->setField(9, "ADT^A24"); print $seg->getField(1);

DESCRIPTION

14       The Net::HL7::Segments::MSH is an implementation of the
15       Net::HL7::Segment class. The MSH segment is a bit different from other
16       segments, in that the first field is the field separator after the
17       segment name. Other fields thus start counting from 2!  The setting for
18       the field separator for a whole message can be changed by the setField
19       method on index 1 of the MSH for that message.  The MSH segment also
20       contains the default settings for field 2, COMPONENT_SEPARATOR,
21       REPETITION_SEPARATOR, ESCAPE_CHARACTER and SUBCOMPONENT_SEPARATOR.
22       These fields default to ^, ~, \ and & respectively.

METHODS

25       $msh = new Net::HL7::Segments::MSH([$fields])
26           Create an instance of the MSH segment. If a reference to an array
27           is given, all fields will be filled from that array. Note that for
28           composed fields and subcomponents, the array may hold subarrays and
29           subsubarrays. If the reference is not given, the MSH segment will
30           be created with the MSH 1,2,7,10 and 12 fields filled in for
31           convenience.
32
33       setField($index, $value)
34           Set the field specified by index to value. Indices start at 1, to
35           stay with the HL7 standard. Trying to set the value at index 0 has
36           no effect. Setting the value on index 1, will effectively change
37           the value of Net::HL7::Message::FIELD_SEPARATOR for the message
38           containing this segment, if the value has length 1; setting the
39           field on index 2 will change the values of COMPONENT_SEPARATOR,
40           REPETITION_SEPARATOR, ESCAPE_CHARACTER and SUBCOMPONENT_SEPARATOR
41           for the message, if the string is of length 4.
