make_set
Description

Create a set from one or more values.

Synopsis
template <typename T0, typename T1,... typename TN>
typename result_of::make_set<T0, T1,... TN>::type
make_set(T0 const& x0, T1 const& x1... TN const& xN);

For C++11 compilers, the variadic function interface has no upper bound.

For C++03 compilers, the variadic function accepts 0 to FUSION_MAX_SET_SIZE elements, where FUSION_MAX_SET_SIZE is a user definable predefined maximum that defaults to 10. You may define the preprocessor constant FUSION_MAX_SET_SIZE before including any Fusion header to change the default. Example:

#define FUSION_MAX_SET_SIZE 20
Parameters

Parameter

Requirement

Description

x0, x1,... xN
