Trait metafunction indicating that `TYPE` provides a BDE‐style `print` method.

== Synopsis

Declared in `<bdlb_printmethods.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class TYPE>
struct HasPrintMethod
    : bslmf::DetectNestedTrait<TYPE, HasPrintMethod>::type
----

== Description

A class, `TYPE`, should specialize this trait to derive from `true_type` if it has a `print` method with the following signature: ` bsl::ostream& print(bsl::ostream& stream, int level = 0, int spacesPerLevel = 4) const; `
