:mrdocs:

This `struct` provides a namespace for utility functions used to construct `Bind` and `BindWrapper` objects. Four families of factory methods are provided: `bind`, `bindR`, `bindS`, and `bindSR`. All factory methods accept an invocable object, optionally followed by up to fourteen additional arguments. Each argument can be either a literal value, a place‐holder, or another `Bind` or `BindWrapper` object.

== Synopsis

Declared in `<bdlf_bind.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]

class BindUtil;

== Description

The `BindUtil` class methods compute the signature of the function object automatically, including the return type, and return a binder object with the specified bound functor and bound arguments. Memory for copying the bound functor and bound arguments is supplied by the user specified allocator if `bindS`, or `bindSR` is used, or the currently installed default allocator, if `bind` or `bindR` is used. The return type is inferred by using `bslmf::FunctionPointerTraits` for free function references and pointers, `bslmf::MemberFunctionPointerTraits` for member function pointers, and `typenname t_FUNC::ResultType` for a functor of type `t_FUNC`.

The `bindR` and `bindSR` variations must be used when binding to an object for which a result type cannot be automatically determined.
