Accessing SubStrings

SourcePro Core : Internationalization Module User’s Guide : Character and String Processing : Representing Strings : Accessing SubStrings

In the Internationalization Module, RWUSubString and RWUConstSubString provide access to a range of characters within a referenced RWUString:

RWUSubString allows read-write access to a range of code units within a referenced RWUString.

RWUConstSubString allows read-only access to a range of code units within a referenced RWUString.

The range within a referenced RWUString is defined by a starting position and an extent. For example, the 7th through the 11th elements, inclusive, would have a starting position of 6 and an extent of 5.

There are no public constructors for substrings. Substrings are constructed by various functions of the RWUString class. Typically, substrings are created and used anonymously, then destroyed immediately. For example:

RWUString str("Hello World");

str(6, 5) = "Mom";
