CPaddingNone Class Reference
| class CPaddingNone : public CPadding |
This concrete subclass of CPadding appends no padding.
aOutput will be a copy of aInput after any call to PadL() or UnPadL().

Constructor & Destructor Documentation
CPaddingNone(TInt)
| IMPORT_C | CPaddingNone | ( | TInt | aBlockBytes | ) | [protected] |
Parameters
| TInt aBlockBytes | The block size in bytes. |
CPaddingNone(void)
| CPaddingNone | ( | void | | ) | [private] |
CPaddingNone(const CPaddingNone &)
Member Functions Documentation
DoPadL(const TDesC8 &, TDes8 &)
| void | DoPadL | ( | const TDesC8 & | aInput, |
| | TDes8 & | aOutput |
| | ) | [private, virtual] |
MaxPaddedLength(TInt)
|
TInt
| MaxPaddedLength | ( | TInt | aInputBytes | ) | const [virtual] |
Gets the size of the aOutput buffer, in a call to PadL(), must be in order to accommodate a block size of BlockSize() and an input size of aInputBytes.
Note:
By default, this function returns the output of BlockSize(). If a derived padding system outputs more than a single block of padding, one must override this function and return the appropriate value.
Parameters
| TInt aInputBytes | The amount of data to be padded out in bytes. |
MinPaddingLength(void)
|
TInt
| MinPaddingLength | ( | void | | ) | const [virtual] |
Gets the smallest number of bytes that PadL() will ever add to aInput in order to get a valid block aligned aOutput.
For example, in SSLv3 padding, if the block size is 8 and aInput is 7 bytes, it will append 1 byte of padding. For SSLv3 padding, this is the smallest amount possible as an 8 byte input will add another block size (8 more bytes) of padded data.
NewLC(TInt)
Creates a new CPaddingNone object and leaves a pointer to it on the cleanup stack.
UnPadL(const TDesC8 &, TDes8 &)
| void | UnPadL | ( | const TDesC8 & | aInput, |
| | TDes8 & | aOutput |
| | ) | [virtual] |
Removes padding from aInput and appends unpadded result to aOutput.
Parameters
| const TDesC8 & aInput | Data to be unpadded. |
| TDes8 & aOutput | On return, the unpadded data. |
operator=(const CPaddingNone &)
