Class RTextBuf

RTextBuf

Support

Supported from 5.0

Description

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) .

Defined in RTextBuf:
MaxLength(), RTextBuf(), SetMaxLengthL(), SetText(), Text(), ~RTextBuf()

TInt MaxLength() const;

Description

void SetText(const TDesC &aDes);

Description

Sets the text.

You must have set the maximum length appropriately first with SetMaxLengthL().

void SetMaxLengthL(TInt aMaxLength);

Description

Attempts to store text beyond the maximum length cause a panic, as with descriptors.
