template<typename targetidentifierT >

nest::STDPConnectionHom< targetidentifierT >::STDPConnectionHom

(

)

Default Constructor.

Sets default values for all parameters. Needed by GenericConnectorModel.

template<typename targetidentifierT >

nest::STDPConnectionHom< targetidentifierT >::STDPConnectionHom

(

const STDPConnectionHom< targetidentifierT > &

rhs

)

Copy constructor from a property object.

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