Typedef Documentation

regex_t_sptr

typedef std::shared_ptr< regex_t > regex_t_sptr

A convenience typedef for a shared pointer of regex_t.

Definition at line 87 of file abg-fwd.h.

Function Documentation

compile()

regex_t_sptr compile

(

const std::string &

str

)

Compile a regex from a string.

The result is held in a shared pointer. This will be null if regex compilation fails.

Parameters

str	the string representation of the regex.

Returns

shared pointer holder of a compiled regex object.

Definition at line 111 of file abg-regex.cc.

generate_from_strings()

std::string generate_from_strings

(

const std::vector< std::string > &

strs

)

Generate a regex pattern equivalent to testing set membership.

A string will match the resulting pattern regex, if and only if it was present in the vector.

Parameters

strs	a vector of strings

Returns

a regex pattern

Definition at line 88 of file abg-regex.cc.

match()

bool match	(	const regex_t_sptr &	r,
		const std::string &	str
	)

See if a string matches a regex.

Parameters

r	a shared pointer holder of a compiled regex object.
str	a string.

Returns

whether there was a match.

Definition at line 127 of file abg-regex.cc.

operator<<()

std::ostream & operator<<	(	std::ostream &	os,
		const escape &	esc
	)

Escape regex special charaters in input string.

Parameters

os	the output stream being written to.
esc	the regex_escape object holding a reference to the string needing to be escaped.

Returns

the output stream.
