Class TDes8Overflow

class TDes8Overflow;

Description

An interface that defines an overflow handler for an 8-bit descriptor.

The interface encapsulates a function that is called when an attempt to append formatted text fails because the descriptor is already at its maximum length.

A derived class must provide an implementation for the TDes8Overflow::Overflow(TDes8 &) member function.

Members

Defined in TDes8Overflow:

• Overflow(TDes8 &)Handles the overflow.

See also:

• TDes8::AppendFormat(TRefByValue< const TDesC8 >,TDes8Overflow *,...)Formats and appends text onto the end of this descriptor's data.

virtual void Overflow(TDes8 &aDes)=0;

Description

Handles the overflow.

This function is called when the TDes8::AppendFormat(TRefByValue< const TDesC8 >,TDes8Overflow *,...) variant that takes an overflow handler argument, fails.

Parameters

TDes8 &aDes The 8-bit modifiable descriptor whose overflow results in the call to this overflow handler.
