Detailed Description
template<class T>
class TMCClassArray< T >
TMCClassArray is an array used to store structs or classes that need a constructor or a destructor. For example, you can use it with TMCDynamicString and the memory used by the strings will be freed when the array is destroyed.
Indexes to access the Array classes are ZERO based (array[0] gives you the first element)
Arrays grows dynamically as you add elements, so it is very dangerous to keep pointers to elements of the array: if the array is reallocated, your pointers will become invalid. In this case, you should use indexes. For better efficiency, preallocate the number of elements you'll need (or use an estimation of the space if possible).
In eSmartGrow mode (the default), the size of the extra space added when the array is reallocated (the grow size) depends on the number of elements already in the array. Otherwise, a constant grow size is used.
Other array classes are: TMCArray, TMCPtrArray, TMCCountedPtrArray, and TMCExtensibleArray.
Member Typedef Documentation
Constructor & Destructor Documentation
Constructs an array with a certain number of elements already accessible (and constructed).
- Parameters:
-
| initialCount | initial number of array elements. |
Constructs an array with a certain number of elements already accessible (and constructed), and/or some extra space to extend the array without reallocating it.
- Note:
- This constructor turns off eSmartGrow, so the grow size is constant
- Parameters:
-
| initialCount | Initial number of array elements. |
| initialSpace | Pre-allocate space for this many elements (must be bigger than initialCount). |
| initialGrowSize | How many elements to grow the array when we grow past the end |
Copy constructor: Construct an array from an existing array.
Constructs an array from existing memory.
- Note:
- : If you pass inAquireMemory = false then this array CANNOT grow past elemSpace, and will not free the memory passed in.
- Parameters:
-
| baseAddress | External memory to use for this array. |
| inAquireMemory | Should we take possession this memory. |
| elemCount | The number of array elements in use in that memory. |
| elemSpace | The number of array elements that can be used in that memory. |
Constructs an alias to an existing array.
- Note:
- : This array CANNOT grow past elemSpace, and will not free the memory passed in. Also this array is an alias to the array passed in NOT a copy so be carefull.
- Parameters:
-
| array | Alias elements from this array. |
| elemStart | Start alias here. |
| elemCount | Alias this many elements. |
Destructs the elements of the array and frees the memory (if the array owns it).
Member Function Documentation

| | [inline] |
Fill an array range with the value passed in.
Finds the index in this array of the given element
- Note:
- Requires that T implements an operator ==
- Parameters:
-
| elemToFind | the element to search for |
- Returns:
- kUnusedIndex if elemToFind is not in the array, otherwise a valid index
Returns a reference to the first element in the array.
Returns a reference to the first element in the array.
Get the contents of arrray index into the passed in data reference.
Returns the actual number of (valid) elements in the array. Those elements can be accessed with the operator []
Returns the size of one element
Returns the number of elements that can be stored in the array (before the next reallocation)
Returns the size by which the array grows
Returns true if the grow size is dynamic
Inserts one element at the given index
- Parameters:
-
| index | where to insert |
| data | the data to insert |
Returns true if the element is in the array
returns kNoErr if the given index is valid, kOutOfRangeError otherwise (use with ThrowIfError(array.IsIndexInvalid(i);)
IsValid(): Check to see if the class is valid.
Returns a reference to the last element in the array.
Returns a reference to the last element in the array.
operator=: Assignment operator copies all the data from one array to another.
Returns a reference to the data at the passed in index.
Returns a reference to the data at the passed in index.
Returns a pointer to the data at the passed in index.
Returns a pointer to the data at the passed in index.

- Note:
- Requires that T implements an operator ==
- Parameters:
-
| elemToRemove | the element to remove. |
Remove one or more elements from the array starting from the passed in index.
Set the contents of arrray index to the passed in data reference.
Set the number of elements in the array.

Sets the valid flag to true
Swaps the contents of two arrays.
