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.

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.
void | Set | ( | 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.
const TPtr8 & aPtr | The source 8-bit modifiable pointer descriptor. |
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.
const TUint8 * aString | A pointer to a zero-terminated string. |
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.
const TDesC8 & aDes | An 8-bit modifiable pointer descriptor whose data is to be copied into this descriptor. |
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.
const TPtr8 & aPtr | An 8-bit modifiable pointer descriptor whose data is to be copied into this descriptor. |
