| class TFourCC |
A class that holds a four character code, representing supported data encodings for the conversion destination. The four character codes are packed into a single TUint32.
FourCC codes are a representation of the datatypes used to identify codecs. FourCC codes are used in codec .rss files as a match string used by ECOM to correctly load the required DLL.

Packs the four arguments into a single TUint32.
The four arguments are packed in little-endian format.
| TUint8 aChar1 | A character that represents part of the FourCC code. This character will be the least significant byte of the code. |
| TUint8 aChar2 | A character that represents part of the FourCC code. |
| TUint8 aChar3 | A character that represents part of the FourCC code. |
| TUint8 aChar4 | A character that represents part of the FourCC code. This character will be the most significant byte of the code. |
| TFourCC | ( | const TDesC8 & | aDes | ) | [inline] |
Constructs a FourCC code with the given 8 bit desciptor where the descriptor contains the characters that make up the FourCC code.
| const TDesC8 & aDes | The descriptor containing the characters from which to make the FourCC code. |
| TFourCC | ( | TInt32 | aFourCC | ) | [inline] |
Constructor with a TInt32 in little-endian format.
| TInt32 aFourCC | The FourCC code. |
| TUint32 | FourCC | ( | ) | [inline] |
Returns the FourCC code in little-endian format.
The FourCC code in little-endian format.
| void | FourCC | ( | TPtr8 * | aDes | ) | const [inline] |
Unpacks the FourCC code in little-endian format into the space provided by the argument.
The argument must be a pointer to a buffer of 4 bytes or greater.
| TPtr8 * aDes | A buffer to hold the unpacked FourCC code. |
| void | Set | ( | TFourCC | aFourCC | ) | [inline] |
Sets the FourCC code equal to the value in the supplied argument.
| TFourCC aFourCC | The required TFourCC containting the FourCC code. |
| void | Set | ( | TUint32 | aFourCC | ) | [inline] |
Sets the FourCC code equal to the supplied argument.
| TUint32 aFourCC | The required FourCC code. |
| TBool | operator!= | ( | const TFourCC & | aA | ) | const [inline] |
Inequality operator.
A boolean indicating if the two values are not equal. ETrue if the two values are unequal, otherwise false.
| const TFourCC & aA | The TFourCC code that *this will be tested against. |
| TBool | operator!= | ( | const TUint32 & | aUint | ) | const [inline] |
Inequality operator.
| const TUint32 & aUint | The FourCC code that *this will be tested against. |
| TBool | operator== | ( | const TFourCC & | aA | ) | const [inline] |
Equality operator.
A boolean indicating if the two values are equal. ETrue if the two values are equal, otherwise false.
| const TFourCC & aA | The TFourCC code that *this will be tested against. |
| TBool | operator== | ( | const TUint32 & | aUint | ) | const [inline] |
Equality operator.
A boolean indicating if the two values are equal. ETrue if the two values are equal, otherwise false.
| const TUint32 & aUint | The FourCC code that *this will be tested against. |
