NAME

perfSONAR_PS::Datatypes::v2_0::nmwgt::Message::Metadata::Subject::EndPointPair::Dst  - A base class, implements  'dst'  element from the perfSONAR_PS RelaxNG schema

DESCRIPTION

Object representation of the dst element.
Object fields are:
 Scalar:     value, 
 Scalar:     type, 
 Scalar:     port, 

The constructor accepts only single parameter, it could be a hashref to parameters hash  or DOM with  'dst' element

SYNOPSIS

             use perfSONAR_PS::Datatypes::v2_0::nmwgt::Message::Metadata::Subject::EndPointPair::Dst;
         
         my $el =  perfSONAR_PS::Datatypes::v2_0::nmwgt::Message::Metadata::Subject::EndPointPair::Dst->new($DOM_Obj);

METHODS

new( )

creates   object, accepts DOM with  element tree or hashref to the list of
keyd parameters
   value   => undef, 
   type   => undef, 
   port   => undef, 
text => 'text'

getDOM ($)

     accept parent DOM
     return dst object DOM, generated from object contents

querySQL ()

  depending on config  it will return some hash ref  to the initialized fields
for example querySQL ()
accepts one optional prameter - query hashref
will return:
{ ip_name_src =>  'hepnrc1.hep.net' },}

merge

merge with another dst ( append + overwrite if exists )
we can do it differently
method #1:
   convert to dom both objects and then get resulted object from combined dom 
method #2 default:
   through the introspection of the object

buildIdMap()

if any of subelements has id then get a map of it in form of
hashref to { element}{id} = index in array and store in the idmap field

buildrefIdMap ()

if any of subelements has  metadataIdRef  then get a map of it in form of
hashref to { element}{ metadataIdRef } = index in array and store in the idmap field

asString()

shortcut to get DOM and convert into the XML string
returns XML string  representation of the  dst object

registerNamespaces ()

will parse all subelements and register all namepspaces within the dst namespace

fromDOM ($)

accepts parent XML DOM   element   tree as parameter 
returns dst  object
