RArray Class Reference

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&)

3.3 Insert(const T&, TInt)

3.4 the [] operator, and then using the pointer to iterate through the array as you would with a C array.

RArray(TInt, TInt, TInt)

RArray(TIntaMinGrowBy,
TIntaKeyOffset,
TIntaFactor
)[inline]

panic

USER 129, if the size of class T is not positive or is not less than 640.

panic

RArray(TInt, T *, TInt)

RArray(TIntaEntrySize,
T *aEntries,
TIntaCount
)[inline]

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.

panic

USER 129, if aEntrySize is not positive or is not less than 640.

panic

USER 156, if aCount is not positive.

Parameters

TInt aEntrySizeThe size of an entry in the existing array.
T * aEntriesA pointer to the first entry of type class T in the set of entries belonging to the existing array.
TInt aCountThe number of entries in the existing array.

Member Functions Documentation

Append(const T &)

TInt Append(const T &anEntry)[inline]

Apends an object onto the array.

KErrNone, if the insertion is successful, otherwise one of the system wide error codes.

Parameters

const T & anEntryA reference to the object of type class T to be appended.

AppendL(const T &)

voidAppendL(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.

Parameters

const T & anEntryA reference to the object of type class T to be appended.

Array()

TArray< T >Array()const [inline]

Constructs and returns a generic array.

A generic array representing this array.

Close()

voidClose()[inline]

Closes the array and frees all memory allocated to the array.

The function must be called before this array object is destroyed.

Compress()

voidCompress()[inline]

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.

Count()

TInt Count()const [inline]

Gets the number of objects in the array.

The number of objects in the array.

Find(const T &)

TInt Find(const T &anEntry)const [inline]

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.

The index of the first matching object within the array. KErrNotFound, if no matching object can be found.

Parameters

const T & anEntryA reference to an object of type class T to be used for matching.

Find(const T &, TIdentityRelation< T >)

TInt Find(const T &anEntry,
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>());

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.

The index of the first matching object within the array. KErrNotFound, if no matching object can be found.

Parameters

const T & anEntryA reference to an object of type class T to be used for matching.

Parameters

const K & aKeyThe key of type K to be compared with the elements of the array using apfnCompare.
TBool(*)(const K *k, const T &t) apfnCompareA function defining the identity relation between the object in the array, and their keys of type K. The function returns true if k and t match based on this relationship.

TInt & anIndexA TInt type supplied by the caller. On return, it contains an index value depending on whether a match is found and on the value of aMode. If there is no matching element in the array, then this is the index of the first element in the array that is bigger than the element being searched for - if no elements in the array are bigger, then the index value is the same as the total number of elements in the array. If there is a matching element, then what the index refers to depends on the value of aMode: if this is EArrayFindMode_First, then the index refers to the first matching element; if this is EArrayFindMode_Any, then the index can refer to any of the matching elements; if this is EArrayFindMode_Last, then the index refers to first element that follows the last matching element - if the last matching element is also the last element of the array, then the index value is the same as the total number of elements in the array.
TInt aModeSpecifies whether to find the first match, the last match or any match, as defined by one of the TArrayFindMode enum values.

operator[](TInt)

const T &operator[](TIntanIndex)const [inline]

Gets a reference to an object located at a specified position within the array.

The compiler chooses this function if the returned reference is used in an expression where the reference cannot be modified.

A const reference to the object at position anIndex within the array.

panic

USER 130, if anIndex is negative or is greater than the number of objects currently in the array

Parameters

TInt anIndexThe position of the object within the array. The position is relative to zero, i.e. zero implies the object at the beginning of the array.

operator[](TInt)

T &operator[](TIntanIndex)[inline]

Gets a reference to an object located at a specified position within the array.

The compiler chooses this function if the returned reference is used in an expression where the reference can be modified.

A non-const reference to the object at position anIndex within the array.

panic

USER 130, if anIndex is negative or is greater than the number of objects currently in the array

Parameters

TInt anIndexThe position of the object within the array. The position is relative to zero, i.e. zero implies the object at the beginning of the array.
