TPtr8 Class Reference

class TPtr8 : public TDes8

8-bit modifiable pointer descriptor.

This is a descriptor class intended for instantiation and encapsulates a pointer to the 8-bit data that it represents. The data can live in ROM or RAM and this location is separate from the descriptor object itself.

The data is intended to be accessed and modified through this descriptor. The base classes provide the functions through which the data can be manipulated.

Set(TUint8 *, TInt, TInt)

voidSet(TUint8 *aBuf,
TIntaLength,
TIntaMaxLength
)[inline]

Sets the 8-bit modifiable pointer descriptor to point to the specified location in memory, whether in RAM or ROM.

The length of the descriptor and its maximum length are set to the specified values.

panic

USER 20, if aLength is negative or is greater than the maximum length of this descriptor.

panic

USER 30, if aMaxLength is negative.

Parameters

TUint8 * aBufA pointer to the location that the descriptor is to represent.
TInt aLengthThe length of the descriptor.
TInt aMaxLengthThe maximum length of the descriptor.

Set(const TPtr8 &)

voidSet(const TPtr8 &aPtr)[inline]

Sets the 8-bit modifiable pointer descriptor from an existing 8-bit modifiable pointer descriptor.

It is set to point to the same data, is given the same length and the same maximum length as the source pointer descriptor.

Parameters

const TPtr8 & aPtrThe source 8-bit modifiable pointer descriptor.

operator=(const TUint8 *)

TPtr8 &operator=(const TUint8 *aString)[inline]

Copies data into this 8-bit modifiable pointer descriptor replacing any existing data.

The length of this descriptor is set to reflect the new data.

A reference to this 8-bit modifiable pointer descriptor.

panic

USER 23, if the length of the string, excluding the zero terminator, is greater than the maximum length of this descriptor.

Parameters

const TUint8 * aStringA pointer to a zero-terminated string.

operator=(const TDesC8 &)

TPtr8 &operator=(const TDesC8 &aDes)[inline]

Copies data into this 8-bit modifiable pointer descriptor replacing any existing data.

The length of this descriptor is set to reflect the new data.

A reference to this 8-bit modifiable pointer descriptor.

panic

USER 23, if the length of aDes is greater than the maximum length of this descriptor.

Parameters

const TDesC8 & aDesAn 8-bit modifiable pointer descriptor whose data is to be copied into this descriptor.

operator=(const TPtr8 &)

TPtr8 &operator=(const TPtr8 &aPtr)[inline]

Copies data into this 8-bit modifiable pointer descriptor replacing any existing data.

The length of this descriptor is set to reflect the new data.

A reference to this 8-bit modifiable pointer descriptor.

panic

USER 23, if the length of aDes is greater than the maximum length of this descriptor.

Parameters

const TPtr8 & aPtrAn 8-bit modifiable pointer descriptor whose data is to be copied into this descriptor.
