C++ Binding to Eina_Stringshare.
This class allows you to store a single copy of a string, and use in multiple places throughout your program.
This is a method to reduce the number of duplicated strings kept in memory. It's pretty common for the same strings to be dynamically allocated repeatedly between applications and libraries, especially in circumstances where you could have multiple copies of a structure that allocates the string. So rather than duplicating and freeing these strings, you request a read-only pointer to an existing string and only incur the overhead of a hash look-up.
It sounds like micro-optimizing, but profiling has shown this can have a significant impact as you scale the number of copies up. It improves string creation/destruction speed, reduces memory use and decreases memory fragmentation, so a win all-around.

Check if two eina::stringshare
objects represent the same string.
true
if the strings of the objects are equal, false
otherwise.This operator checks if two eina::stringshare
objects represent the same string. Because of the nature of the objects, this operation falls into a simple pointer comparison, since identical strings are represented by the same instance.

Check if two eina::stringshare
objects represent different strings.
true
if the strings of the objects are different, false
otherwise.This function essentially returns the opposite of operator==(stringshare const& lhs, stringshare const& rhs).

Compare an eina::stringshare
object with a c-like string.
true
if the content of the eina::stringshare
string is equal the content of the given string, false
otherwise. References efl::eina::stringshare::c_str().

true
if the content of the eina::stringshare
string is different from content of the given string, false
otherwise.
