VariableLengthVector is intended to represent an array whose length can be defined at run-time.
This class is templated over the data type. This data-type is meant to be a scalar, such as float, double etc...
Arrays
. 1. FixedArray - Compile time fixed length arrays that's intended to represent an enumerated collection of n
entities. 2. Array - Run time resizeable array that is intended to hold a collection of n
entities 3. Vector - Compile time fixed length array that is intended to hold a collection of n
data types. A vector usually has a mathematical meaning. It should only be used when mathematical operations such as addition, multiplication by a scalar, product etc make sense. 4. VariableLengthVector - Run time array that is intended to hold a collection of scalar data types. Again, it should be used only when mathematical operations on it are relevant. If not, use an Array. 5. Point - Represents the spatial coordinates of a spatial location. Operators on Point reflect geometrical concepts.VariableLengthVector< bool >

Default constructor. It is created with an empty array it has to be allocated later by assignment
itk::VariableLengthVector< TValueType >::VariableLengthVector | ( | unsigned int | dimension | ) |
Constructor with size. Size can only be changed by assignment
itk::VariableLengthVector< TValueType >::VariableLengthVector | ( | ValueType * | data, | |
unsigned int | sz, | |||
bool | LetArrayManageMemory = false | |||
) |
Constructor that initializes array with contents from a user supplied buffer. The pointer to the buffer and the length is specified. By default, the array does not manage the memory of the buffer. It merely points to that location and it is the user's responsibility to delete it. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.

itk::VariableLengthVector< TValueType >::VariableLengthVector | ( | const VariableLengthVector< T > & | v | ) | [inline] |
Copy constructor. The reason why the copy constructor and the assignment operator are templated is that it will allow implicit casts to be performed. For instance
VariableLengthVector< int > vI; VariableLengthVector< float > vF( vI ); or for instance vF = static_cast< VariableLengthVector< float > >( vI );

Set the pointer from which the data is imported. If "LetArrayManageMemory" is false, then the application retains the responsibility of freeing the memory for this data. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.

void itk::VariableLengthVector< TValueType >::SetData | ( | TValueType * | data, | |

bool | LetArrayManageMemory = false | |||

Similar to the previous method. In the above method, the size must be seperately set prior to using user-supplied data. This introduces an unnecessary allocation step to be performed. This method avoids it and should be used to import data whereever possible to avoid this. Set the pointer from which the data is imported. If "LetArrayManageMemory" is false, then the application retains the responsibility of freeing the memory for this data. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.
