SWIFT::Factory::Tag::Tag21 - Provide a TAG21 for a SWIFT message.
use SWIFT::Factory::Tag::Tag21; my $tag21 = SWIFT::Factory::Tag::Tag21->new( DO_CLEANUP=>0, REFERENCE=>'SOME_REF' );
Tag 21 is used to provide the Related Reference in a SWIFT message. It is up to the sending party to make sure the reference is relevant.
Instantiates a new Tag21 object.
The parameters may be given in arbitrary order. Both parameters have built-in default values. If the calling application doesn't provide a specific parameter at all, the object will apply the default value to that parameter.
Optional. Default value: false
If given with a true value, the object will try to cleanup some of the parameters given. For instance, if
REFERENCE=>is too long, the Tag21 object will truncate it.
If not given, or if given with a false value, it is fully up to the calling application to assure that the given parameters contain reasonable values.
A scalar value that contains a Related Reference for the message. May not be longer than SWIFT::Factory::Tag::Tag21::REF_MAX_LEN.
DO_CLEANUP=>was given a true value, then the value given in
REFERENCE=>will be truncated if it is too long.
Class methods are always called with the fully qualified name, like:
(The new() constructor is a typical example of a class method.)
Returns the maximum length allowed for the Reference in a TAG21. See also the ref_max_len() object method.
Will return the version of this Perl module. (This method is inherited from the UNIVERSAL class.)
A really broken alias for invalid(). Will execute exactly the same code as the invalid() method.
Will return the number of errors detected in the objects instance data.
The class can never be charged to guarrantee that the provided string() will be fully compliant with the SWIFT standards or SWIFT verification rules. It can only point out known problems in the object as it is currently loaded.
Please beware that the current implementation of invalid() doesn't check anything at all. Consider it a placeholder for now. When time permits, the method will be filled with validation code.
As it stands, the method will always return zero since it wasn't able to discover any error at all.
An alias for string(). Will execute exactly the same code as the string() method.
Returns the maximum length allowed for the Related Reference in a TAG21. See also the REF_MAX_LEN() class method.
Get and/or set the Related Reference that will be used when providing the TAG21 string.
Takes one optional parameter, a scalar containing a Related Reference that will be used in all subsequent method calls for this object.
If a Related Reference is provided, it will be stored for future use.
Will return a fully formatted string containing a TAG21 for a SWIFT message.
