class TBuf : public TBufBase16;
A build-independent modifiable buffer descriptor.
This is a descriptor class which provides a buffer of fixed length for containing, accessing and manipulating TUint16 or TUint8 data, depending on the build.
The class is intended for instantiation. The data that the descriptor represents is part of the descriptor object itself.
The class is templated, based on an integer value which determines the size of the data area created as part of the buffer descriptor object; this is also the maximum length of the descriptor.
The data is intended to be both accessed and modified. The base classes provide the functions through which the data is accessed.
This class derives from TBufCBase16 for a Unicode, non-kernel build, but derives from TBufCBase8 for a non-Unicode build.
TBufBase16 - No description.
TBuf - A build-independent modifiable buffer descriptor
Defined in TBuf:
TBuf(), TBuf(), TBuf(), TBuf(), operator=(), operator=(), operator=()
inline TBuf();
Creates a build-independent modifiable buffer descriptor which contains no data.
The integer template parameter determines the size of the data area that is created as part of the object, and defines the descriptor's maximum length.
inline TBuf(TInt aLength);
Constructs an empty build independent modifiable buffer descriptor and sets its length to the specified value.
No data is assigned to the descriptor.
The integer template parameter determines the size of the data area created as part of the object and defines the descriptor's maximum length.
|
|
inline TBuf(const TText *aString);
Constructs the build-independent modifiable buffer descriptor from a zero terminated string.
The integer template parameter determines the size of the data area which is created as part of this object.
The string, excluding the zero terminator, is copied into this buffer descriptor's data area. The length of this buffer descriptor is set to the length of the string, excluding the zero terminator.
|
|
inline TBuf(const TDesC &aDes);
Constructs the build-independent modifiable buffer descriptor from any existing build-independent descriptor.
The integer template parameter determines the size of the data area created as part of this object, and defines the descriptor's maximum length.
Data is copied from the source descriptor into this modifiable buffer descriptor and the length of this modifiable buffer descriptor is set to the length of the source descriptor.
