Detailed Description

Generic non-websocket specific utility functions and data structures.

Function Documentation

ci_find_substr() [1/2]

template<typename T>

T::const_iterator websocketpp::utility::ci_find_substr	(	T const &	haystack,
		T const &	needle,
		std::locale const &	loc = std::locale() )

Find substring (case insensitive).

Parameters

[in]	haystack	The string to search in
[in]	needle	The string to search for
[in]	loc	The locale to use for determining the case of values. Defaults to the current locale.

Returns

An iterator to the first element of the first occurrance of needle in haystack. If the sequence is not found, the function returns haystack.end()

Definition at line 101 of file utilities.hpp.

ci_find_substr() [2/2]

template<typename T>

T::const_iterator websocketpp::utility::ci_find_substr	(	T const &	haystack,
		typename T::value_type const *	needle,
		typename T::size_type	size,
		std::locale const &	loc = std::locale() )

Find substring (case insensitive).

Todo

Is this still used? This method may not make sense.. should use iterators or be less generic. As is it is too tightly coupled to std::string

Parameters

[in]	haystack	The string to search in
[in]	needle	The string to search for as a char array of values
[in]	size	Length of needle
[in]	loc	The locale to use for determining the case of values. Defaults to the current locale.

Returns

An iterator to the first element of the first occurrance of needle in haystack. If the sequence is not found, the function returns haystack.end()

Definition at line 123 of file utilities.hpp.

string_replace_all()

std::string websocketpp::utility::string_replace_all ( std::string subject, std::string const & search, std::string const & replace )

inline

Replace all occurrances of a substring with another.

Parameters

[in]	subject	The string to search in
[in]	search	The string to search for
[in]	replace	The string to replace with

Returns

A copy of subject with all occurances of search replaced with replace

Definition at line 59 of file utilities_impl.hpp.

to_hex() [1/3]

std::string websocketpp::utility::to_hex ( char const * input, size_t length )

inline

Convert char array to ascii printed string of hex digits.

Parameters

[in]	input	The char array to print
[in]	length	The length of input

Returns

A copy of input converted to the printable representation of the hex values of its data.

Definition at line 55 of file utilities_impl.hpp.

to_hex() [2/3]

std::string websocketpp::utility::to_hex ( std::string const & input )

inline

Convert std::string to ascii printed string of hex digits.

Parameters

[in]

input

The string to print

Returns

A copy of input converted to the printable representation of the hex values of its data.

Definition at line 37 of file utilities_impl.hpp.

to_hex() [3/3]

std::string websocketpp::utility::to_hex ( uint8_t const * input, size_t length )

inline

Convert byte array (uint8_t) to ascii printed string of hex digits.

Parameters

[in]	input	The byte array to print
[in]	length	The length of input

Returns

A copy of input converted to the printable representation of the hex values of its data.
