Detailed Description

Class that holds any value, with informations to manipulate it. operator=() makes a shallow copy.

Warning: AnyReference should not be used directly as call arguments. Use qi::AnyValue which has value semantics instead.

T & qi::detail::AnyReferenceBase::as ( )

inline

Read and update functions The following functions access or modify the existing value. They never change the storage location or type. They will fail by throwing an exception if the requested operation is incompatible with the current value type.

Warning: a AnyReference refering to a container element will become invalid as soon as the container is modified.

Returns: a typed reference to the underlying value

Warning: This method will only succeed if T exactly matches the type of the value stored. No conversion will be performed. So if you only want a value and not a reference, use to() instead.

template<typename K >

AnyReference qi::detail::AnyReferenceBase::operator[] ( const K & key )

In-place container manipulation. Return a reference to container element at index or key idx. Use set methods on the result for inplace modification. Behavior depends on the container kind:

List or tuple: The key must be of integral type. Boundary checks are performed.
Map: The key must be of a convertible type to the container key type. If the key is not found in the container, a new default-valued Element will be created, inserted. and returned.
Warning
the returned value is only valid until owning container is changed.

Definition at line 217 of file anyreference.hxx.

template<typename T >

T * qi::detail::AnyReferenceBase::ptr ( bool check = true )

inline

Return the typed pointer behind a AnyReference. T must be the type of the value.

Returns: a pointer to the value as a T or 0 if value is not a T.

Parameters

check if false, does not validate type before converting
