TFixedArray Class Reference
A thin wrapper class for C++ arrays allowing automatic checking of index values to ensure that all accesses are legal.
The class also supports the deletion of objects.
The class is templated, based on a class type and an integer value. The class type defines the type of object contained in the array; the integer value defines the size (dimension) of the array.
A wrapper object can be:
1. embedded in objects allocated on the heap.
2. used on the program stack.

Constructor & Destructor Documentation
TFixedArray()
Default constructor.
Constructs an uninitialised C++ array.
TFixedArray(const T *, TInt)
| TFixedArray | ( | const T * | aList, |
| | TInt | aLength |
| | ) | [inline] |
Constructs a C++ array initialised with the specified objects.
-
panic
- USER 133, in a debug build only, if aLength is negative or is greater than the size of the array as defined by the integer template parameter.
Parameters
| const T * aList | A pointer to a set of contiguous objects. |
| TInt aLength | The number of contiguous objects to be copied. This value must not be negative and must not be greater than the size of the array as defined by the integer template parameter. |
Member Functions Documentation
Array()
|
TArray< T > | Array | ( | ) | const [inline] |
Creates and returns a generic array for this C++ array.
At(TInt)
| T & | At | ( | TInt | aIndex | ) | [inline] |
Gets a reference to the specified element within the C++ array.
-
panic
- USER 133, if aIndex is negative or greater than or equal to the size of the array as defined by the integer template parameter.
Parameters
| TInt aIndex | The position of the element within the array. This is an offset value; a zero value refers to the first element in the array. This value must be greater than or equal to zero and less than the size of the array. |
At(TInt)
| const T & | At | ( | TInt | aIndex | ) | const [inline] |
Gets a const reference to the specified element within the C++ array.
-
panic
- USER 133, in a debug build only, if aIndex is negative or greater than or equal to the size of the array as defined by the integer template parameter.
Parameters
| TInt aIndex | The position of the element within the array. This is an offset value; a zero value refers to the first element in the array. This value must be greater than or equal to zero and less than the size of the array. |
AtFunctionR(const CBase *, TInt)
| const TAny * | AtFunctionR | ( | const CBase * | aThis, |
| | TInt | aIndex |
| | ) | [protected, static, inline] |
Begin()
Gets a pointer to the first element of the array.
Begin()
| const T * | Begin | ( | ) | const [inline] |
Gets a pointer to the first element of the array.
Copy(const T *, TInt)
| void | Copy | ( | const T * | aList, |
| | TInt | aLength |
| | ) | [inline] |
Copies the specified set of contiguous objects into the C++ array.
The copy operation starts at the beginning of the array, replacing any existing data.
-
panic
- USER 133, in a debug build only, if aLength is negative or is greater than the size of the array as defined by the integer template parameter.
Parameters
| const T * aList | A pointer to a set of contiguous objects. |
| TInt aLength | The number of contiguous objects to be copied. This value must not be negative and must not be greater than the size of the array as defined by the integer template parameter. |
Count()
|
TInt
| Count | ( | ) | const [inline] |
Gets the size of the array.
For any instance of this class, the array size is fixed and has the same value as the integer template parameter.
CountFunctionR(const CBase *)
|
TInt
| CountFunctionR | ( | const CBase * | aThis | ) | [protected, static, inline] |
DeleteAll()
Invokes the delete operator on every member of the array.
The function can only be used for arrays of pointers to CBase derived objects.
If the array is to be used after a call to this function, it is good practice to call TFixedArray<class T,TInt S>::Reset() to set all array elements to NULL.
End()
Gets a pointer to the first byte following the end of the array.
End()
| const T * | End | ( | ) | const [inline] |
Gets a pointer to the first byte following the end of the array.
InRange(TInt)
|
TBool
| InRange | ( | TInt | aIndex | ) | [protected, static, inline] |
Length()
|
TInt
| Length | ( | ) | const [inline] |
Gets the size of an array element, in bytes.
Reset()
Fills every element of the array with binary zeroes.
operator[](TInt)
| T & | operator[] | ( | TInt | aIndex | ) | [inline] |
Gets a reference to the specified element within the C++ array.
-
panic
- USER 133, in a debug build only, if aIndex is negative or greater than or equal to the size of the array as defined by the integer template parameter.
Parameters
| TInt aIndex | The position of the element within the array. This is an offset value; a zero value refers to the first element in the array. This value must be greater than or equal to zero and less than the size of the array. |
operator[](TInt)
| const T & | operator[] | ( | TInt | aIndex | ) | const [inline] |
Gets a const reference to the specified element within the C++ array.
-
panic
- USER 133, in a debug build only, if aIndex is negative or greater than or equal to the size of the array as defined by the integer template parameter.
Parameters
| TInt aIndex | The position of the element within the array. This is an offset value; a zero value refers to the first element in the array. This value must be greater than or equal to zero and less than the size of the array. |
