Etymology

This should be viewed as a block of memory without sophisticated manipulation functions. Thus it is called Block.

Synopsis

Block<T> is a simple templated 1-D array class. Indices are always 0-based. For efficiency reasons, no index checking is done unless the preprocessor symbol AIPS_ARRAY_INDEX_CHECK is defined. Block<T>'s may be assigned to and constructed from other Block<T>'s. As no reference counting is done this can be an expensive operation, however.

The net effect of this class is meant to be unsurprising to users who think of arrays as first class objects. The name "Block" is intended to convey the concept of a solid "chunk" of things without any intervening "fancy" memory management, etc. This class was written to be used in the implementations of more functional Vector, Matrix, etc. classes, although it is expected Block<T> will be useful on its own.

The Block class should be efficient. You should normally use Block.


Warning: If you use the assignment operator on an element of this class, you may leave dangling references to pointers released from storage(); Resizing the array will also have this effect if the underlying storage is actually affected;

If index checking is turned on, an out-of-bounds index will generate an indexError<uInt> exception.

Example

Block<Int> a(100,0); // 100 ints initialized to 0
Block<Int> b; // 0-length Block
//..\.
b = a; // resize b and copy a into it
for (size_t i=0; i < a.nelements(); i++) {
a[i] = i; // Generate a sequence
// with Vectors, could simply say "indgen(myVector);"
}
b.set(-1); // All positions in b have the value -1
b.resize(b.nelements()*2); // Make b twice as long, by default the old
// elements are copied over, although this can
// be defeated.
some_c_function(b.storage()); // Use a fn that takes an
// <tt>Int *</tt> pointer

template<class T >
void casacore::Block< T >::remove ( size_t  whichOne,

inline

Remove a single element from the Block.

If forceSmaller is True this will resize the Block and hence involve new memory allocations. This is relatively expensive so setting forceSmaller to False is preferred. When forceSmaller is False the Block is not resized but the elements with an index above the removed element are shuffled down by one. For backward compatibility forceSmaller is True by default.

initPolicy makes sense to determine whether new storage should be initialized or not before copying when forceSmaller is True.

If true, storagePointer is set to NULL. It is strongly recommended to supply an appropriate allocator argument explicitly whenever takeOverStorage == True to let Block to know how to release the storagePointer. The default parameter of allocator will be changed from AllocSpec<NewDelAllocator<T> >value to AllocSpec<DefaultAllocator<T> >value in future. AipsError is thrown if allocator is incompatible with the current allocator of the instance and changing allocator is prohibited, even if takeOverStorage == False.

◆ resize() [2/2]

template<class T >
void casacore::Block< T >::resize ( size_t  n,
Bool  forceSmaller = False,
Bool  copyElements = True 
)
inline

Resizes the Block.

If n == nelements() resize just returns. If a larger size is requested (n > nelements()) the Block always resizes. If the requested size is smaller (n < nelements()), by default the Block does not resize smaller, although it can be forced to with forceSmaller. The reasoning behind this is that often the user will just want a buffer of at least a certain size, and won't want to pay the cost of multiple resizings.

Block<float> bf(100, 0.0);
bf.resize(10); // bf.nelements() == 100
bf.resize(10, True) // bf.nelements() == 10
bf.resize(200) // bf.nelements() == 200
const Bool True
Definition: aipstype.h:43

Normally the old elements are copied over (although if the Block is lengthened the trailing elements will have undefined values), however this can be turned off by setting copyElements to False.

This is written as three functions because default parameters do not always work properly with templates.

initPolicy makes sense to determine whether extended elements should be initialized or not when you enlarge Block.

◆ storage() [1/2]

template<class T >
T* casacore::Block< T >::storage ( )
inline

If you really, really, need a "raw" pointer to the beginning of the storage area this will give it to you.

This may leave dangling pointers if the block is destructed or if the assignment operator or resize is used. Returns a null pointer if nelements() == 0. It is best to only use this if you completely control the extent and lifetime of the Block.

Examples of misuse

Block<Int> *bp = new Block<Int>(100);
Int *ip = bp->storage();
DefaultAllocator<Int>::value.deallocate(bp, bp->capacity()); // Oops, ip is now dangling
Block<Int> a(100),b(100);
Int *ip = a.storage();
a = b; // Likewise
static DefaultAllocator< T > value
an instance of this allocator.
