Member Function Documentation

template<class T>

T& BasicParam::get

(

)

[inline]

Generic getter.

When accessing the datum of a parameter through the base class you should specify the exact type (no automatic conversion implemented).

Reimplemented in Param< T >.

Definition at line 24 of file BasicParam.h.

                  {
    if (type() != typeid(T)) { throw std::bad_cast(); }
    return *(T*)_get_ptr();
  }

template<class T>

const T& BasicParam::get

(

)

const [inline]

Generic getter (const version). see above.

Reimplemented in Param< T >.

Definition at line 30 of file BasicParam.h.

                              {
    if (type() != typeid(T)) { throw std::bad_cast(); }
    return *(T*)_get_ptr();
  }

template<class T>

void BasicParam::set

(

const T &

val

)

[inline]

Generic setter. Same cosideration as for the getters.

Definition at line 37 of file BasicParam.h.

                                {
    if (type() != typeid(T)) { throw std::bad_cast(); }
    *(T*)_get_ptr() = val;
  }

virtual std::string BasicParam::toStr

(

)

const [pure virtual]

String representation for printout.

Implemented in Param< T >, and Param< T >.

virtual std::string BasicParam::toXMLStr	(	const std::string &	name,
		const std::string &	comment = "",
		int	precision = 16
	)			const [pure virtual]

String representation for XML format.

Implemented in Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, Param< T >, and Param< T >.

virtual const std::type_info& BasicParam::type

(

)

const [pure virtual]

TypeId of the datum.

Implemented in Param< T >.

virtual BasicParam* BasicParam::new_copy

(

)

const [pure virtual]

Used for generic copy.

You can copy type-safely a parameter via the base class. (Needed by ParamList)

Implemented in Param< T >.

virtual void* BasicParam::_get_ptr

(

)

[private, pure virtual]

Handle to access the real datum.

Implemented in Param< T >.

virtual const void* BasicParam::_get_ptr

(

)

const [private, pure virtual]

Handle to access the real datum.

Implemented in Param< T >.
