enum phosphor::TraceArgument::Type : char

strong

Enumeration of the possible types of a TraceArgument

Constructor & Destructor Documentation

phosphor::TraceArgument::TraceArgument ( )

default

Default constructor

template<class T >

constexpr phosphor::TraceArgument::TraceArgument ( T  src )

inline

Templated conversion constructor

Parameters

src	Value to be converted to a TraceArgument

Usage:

TraceArgument trace_arg = TraceArgument(arg);

Where arg is one of many primitive types, e.g. int.

Member Function Documentation
