Class TDes16Overflow

class TDes16Overflow;

Description

An interface that defines an overflow handler for a 16-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 TDes16Overflow::Overflow(TDes16 &) member function.

Members

Defined in TDes16Overflow:

• Overflow(TDes16 &)Handles the overflow.

See also:

• TDes16::AppendFormat(TRefByValue< const TDesC16 >,TDes16Overflow *,...)Formats and appends text onto the end of this descriptor's data.

virtual void Overflow(TDes16 &aDes)=0;

Description

Handles the overflow.

This function is called when the TDes16::AppendFormat(TRefByValue< const TDesC16 >,TDes16Overflow *,...) variant that takes an overflow handler argument, fails.

Parameters

TDes16 &aDes The 16-bit modifiable descriptor whose overflow results in the call to this overflow handler.
