Storing text strings

The CommonPoint application system provides a default mechanism for storing character strings. The class TText provides the abstract interface for text instances, and TStandardText provides a concrete implementation that you can use for most text needs. Using TStandardText, you can create and store strings containing up to two billion characters. These text instances form the basis for displayable text anywhere in the system.

The text system supports a wide set of string manipulation capabilities for handling strings of Unicode characters encapsulated by a TText class. See "String function mappings" on page 52 for a table of these functions and how they compare to standard C functions.

The system also includes classes, TUnicodeArray and TToken, that encapsulate unstyled Unicode character arrays for internal manipulation of text strings that you do not need to display. TToken instances can also be shared between programs. See "Encapsulating simple character strings" on page 59 for more information.
