Detailed Description

A MFString is a container of SFString. It is implemented using a STL's deque so you can benefit from its interface. Most common functionnalities you would use are:

   MFString mf;
   mf.push_back(SFString("hello"));  // push_back("hello"); would fail since
   mf.push_front(SFString("world")); // constructor SFString(const char*) is explicit
   mf[0] = "Bye"; // Valid since SFString has operator=(const char*)

but since it uses STL principles, you have all useful concepts such as iterator, algorithms, etc...

Below is included the documentation for this field type from the ISO standard.

5.9 SFString and MFString

The SFString and MFString fields and events contain strings formatted with the UTF-8 universal character set (see 2.[UTF8]). SFString specifies a single string. The MFString specifies zero or more strings. Strings are written to the VRML file as a sequence of UTF-8 octets enclosed in double quotes (e.g., "string").

Any characters (including linefeeds and '#') may appear within the quotes. A double quote character within the string is preceded with a backslash. A backslash character within the string is also preceded with a backslash forming two backslashes. For example:

    fooString [ "One, Two, Three", "He said, \"Immel did it!\"" ]

is an MFString field, fooString, with two valid strings.

The initial value of an SFString eventOut is "" (the empty string). The initial value of an MFString eventOut is [ ].
