| class RArray : private RArrayBase |
A simple and efficient array of fixed length objects.
The elements of the array are instances of a class; this class is specified as the template parameter T.
The array offers standard array behaviour which includes insertion, appending and sorting of elements.
Note:
1. where possible, this class should be used in preference to CArrayFixFlat<classT>.
2. the derivation from RArrayBase is private.
3. for performance reasons, RArray stores objects in the array as word (4 byte) aligned quantities. This means that some member functions do not work when RArray is instantiated for classes of less than 4 bytes in size, or when the class's alignment requirement is not 4. Be aware that it is possible to get an unhandled exception on hardware that enforces strict alignment.
The affected functions are:
3.1 the constructor: RArray(TInt, T*, TInt)
3.2 Append(const T&)
3.4 the [] operator, and then using the pointer to iterate through the array as you would with a C array.
| RArray | ( | ) | [inline] |
Default C++ constructor.
This constructs an array object for an array of type class T objects with default granularity and key offset value. The default granularity is 8 and the defaul key offset value is zero.
| RArray | ( | TInt | aGranularity | ) | [inline, explicit] |
C++ constructor with granularity.
This constructs an array object for an array of type class T objects with a specified granularity and default key offset value. The default key offset value is zero.
| Parameter | Description |
|---|---|
| aGranularity | The granularity of the array. |
C++ constructor with granularity and key offset.
This constructs an array object for an array of type class T objects with a specified granularity and a specified key offset value.
| Parameter | Description |
|---|---|
| aGranularity | The granularity of the array. |
| aKeyOffset | The key offset. |
C++ constructor with minimum growth step and exponential growth factor.
This constructs an array object for an array of class T objects with the specified minimum growth step and exponential growth factor.
| Parameter | Description |
|---|---|
| aMinGrowBy | The minimum growth step of the array. Must be between 1 and 65535 inclusive. |
| aKeyOffset | The key offset. |
| aFactor | The factor by which the array grows, multiplied by 256. For example 512 specifies a factor of 2. Must be between 257 and 32767 inclusive. |
C++ constructor with size of entry, a pointer to the first array entry in a pre-existing array, and the number of entries in that array.
This constructor takes a pointer to a pre-existing set of entries of type class T objects owned by another RArray object. Ownership of the set of entries still resides with the original RArray object.
This array is assigned a default granularity and key offset value. The default granularity is 8 and the default key offset value is zero.
The purpose of constructing an array in this way is to allow sorting and finding operations to be done without further allocation of memory.
| Parameter | Description |
|---|---|
| aEntrySize | The size of an entry in the existing array. |
| aEntries | A pointer to the first entry of type class T in the set of entries belonging to the existing array. |
| aCount | The number of entries in the existing array. |
| void | AppendL | ( | const T & | anEntry | ) | [inline] |
Apends an object onto the array.
The function leaves with one of the system wide error codes, if the operation fails.
NOTE: This function is NOT AVAILABLE to code running on the kernel side.
| Parameter | Description |
|---|---|
| anEntry | A reference to the object of type class T to be appended. |
| void | Close | ( | ) | [inline] |
Reimplemented from RArrayBase::Close()
Closes the array and frees all memory allocated to the array.
The function must be called before this array object is destroyed.
| void | Compress | ( | ) | [inline] |
Reimplemented from RArrayBase::Compress()
Compresses the array down to a minimum.
After a call to this function, the memory allocated to the array is just sufficient for its contained objects. Subsequently adding a new object to the array always results in a re-allocation of memory.
| TInt | Count | ( | ) | const [inline] |
Reimplemented from RArrayBase::Count()const
Gets the number of objects in the array.
Returns: The number of objects in the array.
Finds the first object in the array which matches the specified object using a sequential search.
Matching is based on the comparison of a TInt value at the key offset position within the objects.
For classes which define their own equality operator (==), the alternative method Find(const T& anEntry, TIdentityRelation<T> anIdentity) is recommended.
The find operation always starts at the low index end of the array. There is no assumption about the order of objects in the array.
| Parameter | Description |
|---|---|
| anEntry | A reference to an object of type class T to be used for matching. |
Returns: The index of the first matching object within the array. KErrNotFound, if no matching object can be found.

| TIdentityRelation< T > | anIdentity | |||
| ) | const [inline] | |||
Finds the first object in the array which matches the specified object using a sequential search and a matching algorithm.
The algorithm for determining whether two class T type objects match is provided by a function supplied by the caller.
Such a function need not be supplied if an equality operator (==) is defined for class T. In this case, default construction of anIdentity provides matching, as in the example below:
//Construct a TPoint and append to an RArray<TPoint> TPoint p1(0,0); RArray<TPoint> points; points.AppendL(p1); //Find position of p1 in points using TIdentityRelation<TPoint> default construction TInt r = points.Find(p1, TIdentityRelation<TPoint>());
