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]haystackThe string to search in
[in]needleThe string to search for
[in]locThe 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]haystackThe string to search in
[in]needleThe string to search for as a char array of values
[in]sizeLength of needle
[in]locThe 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]subjectThe string to search in
[in]searchThe string to search for
[in]replaceThe string to replace with
Returns
A copy of subject with all occurances of search replaced with replace

Definition at line 73 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]inputThe char array to print
[in]lengthThe length of input
Returns
A copy of input converted to the printable representation of the hex values of its data.

Definition at line 69 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]inputThe string to print
Returns
A copy of input converted to the printable representation of the hex values of its data.

Definition at line 43 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]inputThe byte array to print
[in]lengthThe length of input
Returns
A copy of input converted to the printable representation of the hex values of its data.

Definition at line 56 of file utilities_impl.hpp.

◆ to_lower()

std::string websocketpp::utility::to_lower ( std::string const &  in)
inline

Convert a string to lowercase.

Parameters
[in]inThe string to convert
Returns
The converted string
