Detailed Description

template<class A1, class A2, class A3, class A4, class A5, class A6, class A7, class A8, class A9, class A10, class A11, class A12, class A13, class A14, class A15, class A16, class A17>
class bdlb::Variant17< A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, A16, A17 >

This class is a "specialization" of Variant for a fixed number (17) of types. Its 17 template arguments must all be specified (none are defaulted to bslmf::Nil). It provides the same functionality as Variant<A1, A2, ..., A17>.

template<class A1 , class A2 , class A3 , class A4 , class A5 , class A6 , class A7 , class A8 , class A9 , class A10 , class A11 , class A12 , class A13 , class A14 , class A15 , class A16 , class A17 >

inline

Create a variant object in the unset state that uses the currently installed default allocator to supply memory.

Variant17() [2/8]

template<class TYPE_OR_ALLOCATOR >

bdlb::Variant17< A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, A16, A17 >::Variant17 ( const TYPE_OR_ALLOCATOR &  valueOrAllocator )

inlineexplicit

Create a variant object with the specified valueOrAllocator that can be either a value of a type that the variant can hold or an allocator to supply memory. If valueOrAllocator is not a bslma::Allocator *, then the variant will hold the value and type of valueOrAllocator, and use the currently installed default allocator to supply memory. Otherwise, the variant will be unset and use valueOrAllocator to supply memory. TYPE_OR_ALLOCATOR must be the same as one of the types that this variant can hold or be convertible to bslma::Allocator *. Note that this parameterized constructor is defined instead of two constructors (one taking a bslma::Allocator * and the other not) because template parameter arguments are always a better match than derived-to-base conversion (a concrete allocator pointer converted to bslma::Allocator *).

Variant17() [3/8]

inline

Create a variant object having the specified value of template parameter TYPE and that uses the specified basicAllocator to supply memory. If basicAllocator is 0, the currently installed default allocator is used. TYPE must be the same as one of the types that this variant can hold.

inline

Create a variant object having the type and value of the specified original variant. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used.

inline

Create a variant object having the type and value of the specified original object by moving the contents of original to the newly-created object. The allocator associated with original (if any) is propagated for use in the newly-created object. original is left in a valid but unspecified state.

inline

Create a variant object having the type and value of the specified original object that uses the specified basicAllocator to supply memory.
