RTextBuf Class Reference

class RTextBuf

A simple class that encapsulates a text string.

As with the descriptor classes, the class sets a maximum length for the encapsulated string, which cannot be exceeded. The class might be preferred to a descriptor in some circumstances as its maximum length can be increased (unlike a TBuf ), and it can be created on the stack (unlike an HBufC) .
