wxString GetRefDesPrefix(const wxString &aRefDes)
Get the (non-numeric) prefix from a refdes - e.g.
wxString GetRefDesUnannotated(const wxString &aSource)
Return an unannotated refdes from either a prefix or an existing refdes.
int GetRefDesNumber(const wxString &aRefDes)
Get the numeric suffix from a refdes - e.g.
Collection of utility functions for component reference designators (refdes)
