Wrapper classes

Detailed Description

All wrapper classes inherit from Wrapper.

Native open62541 objects can be accessed using the Wrapper::handle() member function.

Wrapper types are pointer-interconvertible to the wrapped native type and vice versa:

• Use asWrapper(NativeType*) to cast native object pointers to wrapper object pointers.
• Use asWrapper(NativeType&) to cast native object references to wrapper object references.
• Use asNative(WrapperType*) to cast wrapper object pointers to native object pointers.
• Use asNative(WrapperType&) to cast wrapper object references to native object references.

According to the standard:

‍Two objects a and b are pointer-interconvertible if: One is a standard-layout class object [wrapper] and the other is the first non-static data member of that object [wrapped native type].

Derived classes must fulfill the requirements of standard-layout types to be convertible.

String toString ( const T &  object, const UA_DataType &  type  )

related

Converts an object to its string representation.

This function wraps UA_print to generate a string representation of the given object, based on its data type description.

Note

Requires open62541 v1.2 or later. The open62541 library must be compiled with the UA_ENABLE_TYPEDESCRIPTION option. If these conditions are not met, the function returns an empty String.

Parameters

object	Native or wrapper object.
type	Data type of object.

asWrapper() [1/4]

template<typename WrapperType , typename NativeType = typename WrapperType::NativeType>

constexpr WrapperType * asWrapper ( NativeType *  native )

related

Cast native object pointers to Wrapper object pointers.

This is especially helpful to avoid copies in getter methods of composed types.
