Member Function Documentation

virtual IT_Bus::Boolean IT_Reflect::Nillable::get_is_nil (   )  const throw ((ReflectException)) [pure virtual]

Determine if the instance is nill. Returns: Boolean Exceptions: ReflectException  Implemented in IT_Reflect::NillableRawPtrImplT< T >, and IT_Reflect::NillableValueImplT< NillableT, T >.

virtual const Reflection* IT_Reflect::Nillable::get_value (   )  const throw ((ReflectException)) [pure virtual]

Get a read-only reflection of the value. Returns: Reflection of value or 0 if nil. Exceptions: ReflectException  Implemented in IT_Reflect::NillableRawPtrImplT< T >, and IT_Reflect::NillableValueImplT< NillableT, T >.

virtual void IT_Reflect::Nillable::set_is_nil (   )  throw ((ReflectException)) [pure virtual]

Set the instance to be nil. Returns: void Exceptions: ReflectException  Implemented in IT_Reflect::NillableRawPtrImplT< T >, and IT_Reflect::NillableValueImplT< NillableT, T >.

virtual Reflection* IT_Reflect::Nillable::use_value (   )  throw ((ReflectException)) [pure virtual]

Get a reflection that can be used to modify the value. This makes get_is_nil() false. Returns: Modifiable reflection of value. Caller must _remove_ref(). Exceptions: ReflectException  Implemented in IT_Reflect::NillableRawPtrImplT< T >, and IT_Reflect::NillableValueImplT< NillableT, T >.
