## Detailed Description

### template<unsigned int N, class T, class A>
class vigra::MultiArray< N, T, A >

Main `MultiArray` class containing the memory management.

This class inherits the interface of MultiArrayView, and implements the memory ownership. MultiArray's are always unstrided, striding them creates a MultiArrayView.

The template parameters are as follows

        N: the array dimension

        T: the type of the array elements

        A: the allocator used for internal storage management
           (default: std::allocator<T>)

#include <vigra/multi_array.hxx>

Namespace: vigra

## Member Function Documentation

void allocate | ( | pointer & | ptr,
|  | MultiArrayView< N, U, C > const & | init |
| ) |  |  | `[protected]`

allocate memory, write its address into the given pointer and initialize it by copying the data from the given MultiArrayView.

|  | difference_type_1 | s,
|  | U const * | init |
| ) |  |  | `[protected]`

allocate memory for s pixels, write its address into the given pointer and initialize the linearized pixels to the values of init.

void allocate | ( | pointer & | ptr,
|  | difference_type_1 | s,
|  | const_reference | init |
| ) |  |  | `[protected]`

allocate memory for s pixels, write its address into the given pointer and initialize the pixels with init.

allocator_type const& allocator | ( |  | ) | const

get the allocator.

const_iterator begin | ( |  | ) | const

sequential const iterator pointing to the first array element.

iterator begin | ( |  | ) |

sequential iterator pointing to the first array element.

Multiply-assignment of a scalar.

Reimplemented from MultiArrayView< N, T >.

MultiArray& operator*= | ( | const MultiArrayView< N, U, C > & | rhs | ) |

Multiply-assignment from arbitrary MultiArrayView. Fails with `PreconditionViolation` exception when the shapes do not match.

MultiArray& operator+= | ( | const T & | rhs | ) |

Add-assignment of a scalar.

Reimplemented from MultiArrayView< N, T >.

MultiArray& operator+= | ( | const MultiArrayView< N, U, C > & | rhs | ) |

MultiArray& operator-= | ( | const T & | rhs | ) |

Subtract-assignment of a scalar.

Reimplemented from MultiArrayView< N, T >.

MultiArray& operator-= | ( | const MultiArrayView< N, U, C > & | rhs | ) |

Subtract-assignment from arbitrary MultiArrayView. Fails with `PreconditionViolation` exception when the shapes do not match.

Reimplemented from MultiArrayView< N, T >.

MultiArray& operator/= | ( | const MultiArrayView< N, U, C > & | rhs | ) |

Divide-assignment from arbitrary MultiArrayView. Fails with `PreconditionViolation` exception when the shapes do not match.

MultiArray& operator= | ( | const MultiArrayView< N, U, C > & | rhs | ) |

assignment from arbitrary MultiArrayView.
If the size of rhs is the same as the left-hand side arrays's old size, only the data are copied. Otherwise, new storage is allocated, which invalidates all objects (array views, iterators) depending on the lhs array.

MultiArray& operator= | ( | const MultiArray< N, T, A > & | rhs | ) |

assignment.
If the size of rhs is the same as the left-hand side arrays's old size, only the data are copied. Otherwise, new storage is allocated, which invalidates all objects (array views, iterators) depending on the lhs array.

void reshape | ( | const difference_type & | shape,
|  | const_reference | init |
| ) |  |  |

Allocate new memory with the given shape and initialize it with the given value.
Note: this operation invalidates all dependent objects (array views and iterators)

void reshape | ( | const difference_type & | shape | ) |

Allocate new memory with the given shape and initialize with zeros.
Note: this operation invalidates all dependent objects (array views and iterators)

void swap | ( | MultiArray< N, T, A > & | other | ) |

Swap the contents with another MultiArray. This is fast, because no data are copied, but only pointers and shapes swapped. Note: this operation invalidates all dependent objects (array views and iterators)
