#define FALCON_REFLECT_INTEGER_FROM	(	obj,
		accessor		)	property = (int64) obj->accessor();\

Little macro to automatize reflection of integers.

See also:

FALCON_REFLECT_STRING_FROM

Parameters:

	obj	the object (pointer) containing the string to be reflected.
	accessor	the name of the accessor used to read the variable.

#define FALCON_REFLECT_INTEGER_TO	(	obj,
		accessor		)

Value:

if ( ! property.isOrdinal() ) {\
      throw new ParamError( ErrorParam( e_inv_params ).extra( "N" ) );\
   }\
   obj->accessor( (uint32) property.forceInteger() );\

Little macro to automatize reflection of integers.

See also:

FALCON_REFLECT_STRING_TO

Parameters:

	obj	the object (pointer) containing the string to be reflected.
	accessor	the name of the accessor used to read the variable.

#define FALCON_REFLECT_STRING_FROM	(	obj,
		accessor		)

Value:

if( ! property.isString() )\
      property = new CoreString( obj->accessor() );\
   else\
      property.asString()->bufferize( obj->accessor() );

Little macro to automatize reflection of strings.

This is not a very clean programming technique, but is effective. Used inside a reflectionFunc with parameters named as the standard one (i.e. as those provided in the function declaration), it is able to correctly reflect a string property into an object which provides an accessor to a Falcon::String.

The macro raises a standard parameter error if the property is not a string during setting, and checks for the property being unchanged before resetting it to a new string during reading. As it raises a ParamError, proper .h files (falcon/error.h) must be included.

Used mainly by the engine, users may find it useful.

Parameters:

	obj	the object (pointer) containing the string to be reflected.
	accessor	the name of the accessor used to read the variable.

#define FALCON_REFLECT_STRING_TO	(	obj,
		accessor		)

Value:

if ( ! property.isString() ) {\
      throw new ParamError( ErrorParam( e_inv_params ).extra( "S" ) );\
   }\
   obj->accessor( *property.asString() );\

Little macro to automatize reflection of strings.

This stores the data coming from the engine into the object via an accessor.

Used mainly by the engine, users may find it useful.

FALCON_REFLECT_STRING_FROM

Parameters:

	obj	the object (pointer) containing the string to be reflected.
	accessor	the name of the accessor used to read the variable.
