Constructor & Destructor Documentation

Ensemble() [1/4]

template<typename Tdata >

mspass::seismic::Ensemble< Tdata >::Ensemble ( )

inline

Default constructor.

{};

Ensemble() [2/4]

template<typename Tdata >

mspass::seismic::Ensemble< Tdata >::Ensemble ( const size_t  n )

inline

Reserve space but build empty ensemble.

Often we know what the size of an ensemble is before we start building it. This constructor reserve space but marks all members dead.

Parameters

-	expected number of members.

{member.reserve(n);};

References mspass::seismic::Ensemble< Tdata >::member.

Ensemble() [3/4]

template<typename Tdata >

mspass::seismic::Ensemble< Tdata >::Ensemble ( const mspass::utility::Metadata &  md, const size_t  n  )

inline

Partial constructor to clone metadata and set aside n slots but no data

                                                           : mspass::utility::Metadata(md)
  {
      member.reserve(n);
  };

References mspass::seismic::Ensemble< Tdata >::member.

Ensemble() [4/4]

template<typename Tdata >

mspass::seismic::Ensemble< Tdata >::Ensemble ( const Ensemble< Tdata > &  parent )

inline

Standard copy constructor.

                                   : mspass::utility::Metadata(dynamic_cast<const mspass::utility::Metadata&>(parent)),
    member(parent.member){};

Member Function Documentation

operator=()

template<typename Tdata >

Ensemble& mspass::seismic::Ensemble< Tdata >::operator= ( const Ensemble< Tdata > &  parent )

inline

Standard assignment operator.

  {
    if(this!=(&parent))
    {
      this->Metadata::operator=(parent);
      member=parent.member;
    }
    return *this;
  };

References mspass::seismic::Ensemble< Tdata >::member, and mspass::utility::Metadata::operator=().

sync_metadata()

template<typename Tdata >

void mspass::seismic::Ensemble< Tdata >::sync_metadata ( )

inline

copy ensemble metadata to all members.

An ensemble has global metadata, but each member is required to have a metadata component. This method takes the ensemble metadata and copies it to each of the member objects. The operation will overwrite previous key:value pairs in a member that are also present in the ensemble metadata.

  {
      size_t i;
      for(i=0;i<this->member.size();++i)
      {
          mspass::utility::Metadata *mdmember=&(this->member[i]);
          (*mdmember)+=dynamic_cast<mspass::utility::Metadata&>(*this);
      }
  };

update_metadata()

template<typename Tdata >

void mspass::seismic::Ensemble< Tdata >::update_metadata ( const mspass::utility::Metadata &  newmd )

inline

updates ensemble header (Metadata).

Sometime it is helpful to change a group of header attributes stored in the Metadata component. Rather than do a bunch of puts this uses operator += to update the header. Note this operator uses the property that any existing attributes with the same key as one in the updates set will be replaced with the update.

Parameters

newmd

contains new Metadata to use for updates.

     {
    mspass::utility::Metadata *md;
    md=dynamic_cast<mspass::utility::Metadata*>(this);
    (*md) += newmd;
  }catch(...){throw;};

Member Data Documentation

member

template<typename Tdata >

std::vector<Tdata> mspass::seismic::Ensemble< Tdata >::member

Container holding data objects.

An ensemble is defined as a collection of data objects linked by some property that is normally defined by data sharing a comomon data-value pair. The data are stored here in a vector container. We make this vector public because the assumption is the member objects can be large and copying with a getter would be a serious inefficiently.
