Detailed Description

Base class for all meta-information classes.

Parameters of type ito::Param can have a pointer to this class. Consider this base class to be abstract, such that it is only allowed to pass the right implementation (derived from this class) that fits to the type of the parameter. The runtime type information value m_type indicates the real type of this pointer, such that a direct cast can be executed.

Member Enumeration Documentation

enum ito::ParamMeta::MetaRtti

Runtime type information.

MetaRtti is used to cast param meta objects, without having to enable runtime type information of the compiler.

Enumerator:

rttiUnknown	unknown parameter
rttiCharMeta	meta for a char parameter
rttiIntMeta	meta for an integer parameter
rttiDoubleMeta	meta for a double parameter
rttiStringMeta	meta for a string parameter
rttiHWMeta	meta for a hardware plugin parameter
rttiDObjMeta	meta for a data object parameter
rttiIntArrayMeta	meta for an integer array parameter
rttiDoubleArrayMeta	meta for a double array parameter
rttiCharArrayMeta	meta for a char array parameter
rttiIntervalMeta	meta for an integer array with two values that represent an interval [value1, value2] parameter
rttiDoubleIntervalMeta	meta for a double array with two values that represent an interval [value1, value2] parameter (size of the interval is value2-value1)
rttiRangeMeta	meta for an integer array with two values that represent a range [value1, value2] parameter (size of a range is 1+value2-value1)
rttiRectMeta	meta for an integer array with four values that consists of two ranges (vertical and horizontal, e.g. for ROIs of cameras)
