Member Function Documentation

◆ operator bool()

swoc::bwf::Format::TextViewExtractor::operator bool ( ) const

Definition at line 536 of file bwf_base.h.

◆ operator()()

bool swoc::bwf::Format::TextViewExtractor::operator()	(	std::string_view &	literal_v,
		Spec &	spec )

Parameters

literal_v	[out] The next literal.

Returns: true if spec was filled out, false if no specifier was found.

Definition at line 240 of file bw_format.cc.

◆ parse()

bool swoc::bwf::Format::TextViewExtractor::parse	(	TextView &	fmt,
		std::string_view &	literal,
		std::string_view &	specifier )

static

Parse elements of a format string.

Parameters

fmt	The format string [in\|out]
literal	A literal if found
specifier	A specifier if found (less enclosing braces)

Returns: true if a specifier was found, false if not.

Pull off the next literal and/or specifier from fmt. The return value distinguishes the case of no specifier found (false) or an empty specifier (true).

Parse out the next literal and/or format specifier from the format string. Pass the results back in literal and specifier as appropriate. Update fmt to strip the parsed text.

Returns: true if a specifier was parsed, false if not.
