Lib/typemaps/ptrtypes.swg

/* -----------------------------------------------------------------------------
 * ptrtypes.swg
 *
 * Value typemaps (Type, const Type&) for "Ptr" types, such as swig
 * wrapped classes, that define the AsPtr/From methods
 *
 * To apply them, just use one of the following macros:
 *
 *    %typemaps_asptr(CheckCode, AsPtrMeth, AsPtrFrag, Type)
 *    %typemaps_asptrfrom(CheckCode, AsPtrMeth, FromMeth, AsPtrFrag, FromFrag, Type)
 *
 * or the simpler and normalize form:
 *
 *    %typemaps_asptrfromn(CheckCode, Type)
 *
 * Also, you can use the individual typemap definitions:
 *
 *    %ptr_in_typemap(asptr_meth,frag,Type)
 *    %ptr_varin_typemap(asptr_meth,frag,Type)
 *    %ptr_typecheck_typemap(check,asptr_meth,frag,Type)
 *    %ptr_directorout_typemap(asptr_meth,frag,Type)
 * ----------------------------------------------------------------------------- */
