Member Function Documentation

capture()

virtual std::any swoc::bwf::ArgPack::capture ( unsigned idx ) const

pure virtual

Force virtual destructor for subclasses.

Get argument at index idx.

Parameters

idx	Argument index.

Returns

The argument value.

In general the arguments will be stored by reference and so the returned std::any instance will be a reference type.

Implemented in swoc::bwf::ArgTuple< Args >.

count()

virtual unsigned swoc::bwf::ArgPack::count ( ) const

pure virtual

Number of arguments in the pack.

Implemented in swoc::bwf::ArgTuple< Args >.

print()

virtual BufferWriter & swoc::bwf::ArgPack::print ( BufferWriter & w, Spec const & spec, unsigned idx ) const

pure virtual

Generate formatted output for an argument.

Parameters

w	Output.
spec	Formatting specifier.
idx	Argument index.

Returns

w

Implemented in swoc::bwf::ArgTuple< Args >.
