Hello,
I have implemented a class that contains a multi field of category
'weakpointer' (see extract of fcd file below) representing the beacons of the
lights managed by this class. Now I would like to add a function
setBeacon(const UInt32 idx, Node* beacon) to my class. But I could not succeed
in implementing that function . I always get compile errors. What I expected to
be the right implementation is the following
void MultiRangeLightChunk::setBeacon(const UInt32 idx, Node* const beacon)
{
OSG_ASSERT(idx < _mfBeacon.size());
editMField(BeaconFieldMask, _mfBeacon);
_mfBeacon.replace(idx, beacon);
}
but that is not going to work. I get the following error for that code:
OSGPointerMField.inl(1173): error C2664:
typedef
OSG::PointerMFieldCommon<OSG::PointerAccessHandler<OSG::WeakRefCountPolicy>,0>
PointerMFieldCommon_t
typedef OSG::PointerMField<OSG::Node *,OSG::WeakRefCountPolicy,0>
PointerMField_t
'void
PointerMFieldCommon_t::ptrStoreReplace(PointerMFieldCommon_t::PtrStoreItType,PointerMFieldCommon_t::const_value)'
: cannot convert argument 2 from
'OSG::Node *const ' to
'PointerMFieldCommon_t::const_value'
Types pointed to are unrelated; conversion requires reinterpret_cast,
C-style cast or function-style cast
OSGPointerMField.inl(1172) : while compiling class template member
function 'void PointerMField_t::replace(OSG::UInt32,OSG::Node *const )'
OSGMultiRangeLightChunk.cpp(151) : see reference to function template
instantiation 'void PointerMField_t::replace(OSG::UInt32,OSG::Node *const )'
being compiled
OSGMultiRangeLightChunkBase.h(222) : see reference to class template
instantiation 'PointerMField_t' being compiled
I have tried a lot but do get not my head around this error. Does anyone know
how to write correct setBeacon function in that scenario?
Help is really appreciated here.
Best,
Johannes
