vector_tie

Description

Constructs a tie using a vector sequence.

Synopsis

template <typename T0, typename T1,... typename TN>
vector<T0&, T1&,... TN&>
vector_tie(T0& x0, T1& x1... TN& xN);

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

#define FUSION_MAX_VECTOR_SIZE 20

Parameters

Parameter	Requirement	Description
`x0, x1,... xN`	Instances of `T0, T1,... TN`	The arguments to `vector_tie`

Expression Semantics

vector_tie(x0, x1,... xN);

Return type: vector<T0&, T1&,... TN&>

Semantics: Create a vector of references from x0, x1,... xN.

Example

int i = 123;
