Definition at line 47 of file SetHelper.h.

ICL_CORE_IMPORT_EXPORT std::vector< String > icl_core::split	(	const String &	str,
		const String &	delimiter
	)

Simple string splitting method. Given a string str, which contains substrings separated by delimiter, returns a vector of the substrings. E.g., split("foo;bar;baz") returns a vector containing the elements "foo", "bar" and "baz". If str is empty, returns a vector containing one element, the empty string.

Parameters:

str	The string to split.
delimiter	The delimiter string.

Definition at line 27 of file StringHelper.cpp.

bool ICL_CORE_IMPORT_EXPORT icl_core::string2Enum	(	const String &	str,
		int32_t &	value,
		const char *const *	descriptions,
		const char *	end_marker = NULL
	)

Converts a string to an enumeration value. The descriptions for the individual enumeration values have to be provided in an array, which is terminated by a NULL entry.

Parameters:

str	A string, which should be converted into an enumeration value.
value	The enumeration value into which the result will be written.
descriptions	An array of descriptions for the enumeration values, terminated by the end_marker.
end_marker	The end marker used to terminate the description array.

Returns:

true if str has been found in descriptions. In this case value is set to the corresponding index. false if str could not be found in descriptions.
