	Set (const Options &options, Anchor anchor)
	Starts an empty set.
int	Add (std::string_view pattern, std::string *error)
	Buffers one pattern (validated immediately, like real RE2's Add).

	Compiles every buffered pattern into one real::regex_set.

	Tests text against every compiled member.

Private Member Functions
std::string	anchor_wrap (std::string_view pattern) const
	Synthesizes anchor_'s semantics by wrapping pattern, since real::regex_set is natively unanchored.

Private Attributes
Options	options_
	Options shared by every member.
Anchor	anchor_
	The anchor mode every member is matched with.

	Buffered, already anchor-wrapped member patterns.

Detailed Description

RE2::Set: Add patterns, Compile once, then Match repeatedly, on real::regex_set::which(). The anchor is applied by wrapping each pattern, real::regex_set being unanchored.

Constructor & Destructor Documentation

Set()

real::compat::re2::RE2::Set::Set ( const Options &  options, Anchor  anchor  )

inline

Starts an empty set.

Parameters

[in]	options	The options applied to every member pattern.
[in]	anchor	The anchor mode every member is matched with.

Member Function Documentation

Add()

int real::compat::re2::RE2::Set::Add ( std::string_view  pattern, std::string *  error  )

inline

Buffers one pattern (validated immediately, like real RE2's Add).

Parameters

[in]	pattern	The pattern text.
[out]	error	If non-null and the pattern is rejected, set to a human-readable reason.

Returns

The pattern's index (matches Match's output indices) on success, or -1.

anchor_wrap()

std::string real::compat::re2::RE2::Set::anchor_wrap ( std::string_view  pattern ) const

inlineprivate

Synthesizes anchor_'s semantics by wrapping pattern, since real::regex_set is natively unanchored.

Parameters

[in]

pattern

The raw member pattern text.

Returns

The pattern text to actually compile.

Compile()

bool real::compat::re2::RE2::Set::Compile ( )

inline

Compiles every buffered pattern into one real::regex_set.

Returns

true on success; false when the members together exceed max_mem, as RE2's own Compile fails (each member was already probe-compiled by Add).

Match()

bool real::compat::re2::RE2::Set::Match ( std::string_view  text, std::vector< int > *  v  ) const

inline

Tests text against every compiled member.

Parameters

[in]	text	The subject text.
[out]	v	If non-null, cleared and filled with the indices of every matching member.

Returns

true if at least one member matched.
