Constructor & Destructor Documentation

template<typename targetidentifierT >

nest::STDPDopaConnection< targetidentifierT >::STDPDopaConnection ( )

Default Constructor.

Sets default values for all parameters. Needed by GenericConnectorModel.

template<typename targetidentifierT >

nest::STDPDopaConnection< targetidentifierT >::STDPDopaConnection ( const STDPDopaConnection< targetidentifierT > & rhs )

Copy constructor from a property object.

Needs to be defined properly in order for GenericConnector to work.
