Constructor & Destructor Documentation
TMemBuf()
Constructs an empty object.
Call Set() before using the object.

Base()

TUint8 * | Base | ( | ) | const [private, inline] |
DoSeekL(TMark, TStreamLocation, TInt)
End()

TUint8 * | End | ( | ) | const [private, inline] |
OverflowL()
| IMPORT_C void | OverflowL | ( | ) | [protected, virtual] |
Empties the intermediate buffer and resets the start and end points of the write area.
The implementation of this function depends on the way the stream itself is implemented. For example, the in-memory streams have simple implementations.
Set(TUint8 *, TUint8 *, TInt)
Parameters
| TUint8 * aPtr | The start address for the area of plain memory that hosts the stream and that also acts as the intermediate buffer. |
| TUint8 * anEnd | The end address for the area of plain memory that hosts the stream and that also acts as the intermediate buffer. The addressed byte is outside the memory area. |
| TInt aMode = ERead|EWrite | The mode in which the stream is to be used. It can be used in either or both read and write modes, represented by ERead and EWrite. |
UnderflowL(TInt)
| IMPORT_C TInt | UnderflowL | ( | TInt | aMaxLength | ) | [protected, virtual] |
Re-fills the intermediate buffer and resets the start and end points of the read area.
The implementation of this function depends on the way the stream itself is implemented. For example, the in-memory streams have simple implementations.
Parameters
| TInt aMaxLength | The maximum amount of data required for the intermediate buffer. |
