|
|
The Net-HL7 package is a simple Perl API for creating, parsing sending |
26
|
|
|
|
|
|
|
and receiving HL7 messages. To create an empty HL7 message object, do: |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
=begin text |
29
|
|
|
|
|
|
|
|
30
|
|
|
|
|
|
|
use Net::HL7::Message; |
31
|
|
|
|
|
|
|
|
32
|
|
|
|
|
|
|
my $msg = new Net::HL7::Message(); |
33
|
|
|
|
|
|
|
|
34
|
|
|
|
|
|
|
=end text |
35
|
|
|
|
|
|
|
|
36
|
|
|
|
|
|
|
and add segments like: |
37
|
|
|
|
|
|
|
|
38
|
|
|
|
|
|
|
=begin text |
39
|
|
|
|
|
|
|
|
40
|
|
|
|
|
|
|
my $msh = new Net::HL7::Segments::MSH(); |
41
|
|
|
|
|
|
|
my $pid = new Net::HL7::Segment("PID"); |
42
|
|
|
|
|
|
|
|
43
|
|
|
|
|
|
|
$pid->setField(3, "1231313"); |
44
|
|
|
|
|
|
|
|
45
|
|
|
|
|
|
|
$msg->addSegment($msh); |
46
|
|
|
|
|
|
|
$msg->addSegment($pid); |
47
|
|
|
|
|
|
|
|
48
|
|
|
|
|
|
|
=end text |

|
|

|
|

|
For details, please consult the man pages of each specific class, or |
51
|
|
|
|
|
|
|
consult the generated API docs on |
52
|
|
|
|
|
|
|
I. You might also check the test files |
53
|
|
|
|
|
|
|
in the 't' directory for examples. |

|
|
The Net::HL7 class is only used for documentation purposes (the stuff |
56
|
|
|
|
|
|
|
you're reading right now), to set HL7 configuration properties such as |
57
|
|
|
|
|
|
|
control characters on a global level and to provide a version number |
58
|
|
|
|
|
|
|
of the package to the Perl installation process. This can be used in a |
59
|
|
|
|
|
|
|
'require' statement, or to create a dependency from another Perl |
60
|
|
|
|
|
|
|
package. |

63
|
|
|
|
|
|
|
|
64
|
|
|
|
|
|
|
Some HL7 properties may be altered on a global level. Altering the |
65
|
|
|
|
|
|
|
variable makes it changed for this remainder of the lifetime of this |
66
|
|
|
|
|
|
|
Perl process. All HL7 messages will use the values provided here, |
67
|
|
|
|
|
|
|
unless something is changed in the MSH segment concerning these |
68
|
|
|
|
|
|
|
properties. |
