=head1 NAME

    perfSONAR_PS::Datatypes::EventTypes::Ops -  a container for various perfSONAR http://ggf.org/ns/nmwg/ops/ eventtypes 

=head1 DESCRIPTION

The purpose of this module is to  create OO interface for ops eventtypes  and therefore
add the layer of abstraction for any ops eventtypes  related operation ( mostly for perfSONAR response).
 All  perfSONAR-PS classes should work with the instance of this class and avoid using explicit   eventtype  declarations. 

=head1 SYNOPSIS
 
    use perfSONAR_PS::Datatypes::EventTypes::Ops; 
    
    # create Ops eventtype object with default URIs
    my $ops_event = perfSONAR_PS::Datatypes::EventTypes::Ops->new();
     
    
    # overwrite only specific Namesapce   with  custom URI 
    
    $ops_event  = perfSONAR_PS::Datatypes::EventTypes::Ops->new( {'select' => 'http://ggf.org/ns/nmwg/ops/select/2.0'});
      
    my $select_event = $ops_event->select; ## get URI by key
    
    $ops_event->pinger(  'http://ggf.org/ns/nmwg/ops/select/2.0'); ## set URI by key

=head1 Methods

There is accessor mutator for every defined Characteristic
 
=head2 new( )

Creates a new object, pass hash ref as collection of event types for ops namespace
