## Detailed Description

double-linked list class that maintains pointers to DcmObject instances.

The remove operation does not delete the object pointed to, however, the destructor will delete all elements pointed to

## Constructor & Destructor Documentation

## ◆ DcmList()

DcmList::DcmList | ( | const DcmList & | newList | ) |
| private

private undefined copy assignment operator

Parameters

  newList | documented to avoid doxygen warnings

References DcmList().

## Member Function Documentation

## ◆ append()

DcmObject * DcmList::append | ( | DcmObject * | obj | ) |

insert object at end of list

Parameters

  obj | pointer to object

Returns
  pointer to object

## ◆ deleteAllElements()

void DcmList::deleteAllElements | ( |  | ) |

Remove and delete all elements from list.

Thus, the elements' memory is also freed by this operation. The list is empty after calling this function.

## ◆ get()

DcmObject * DcmList::get | ( | E_ListPos | pos = ELP_atpos | ) |

get pointer to element in list at given position

Parameters

  pos | position indicator

Returns
  pointer to object

## ◆ insert()

DcmObject * DcmList::insert | ( | DcmObject * | obj,
|  | E_ListPos | pos = ELP_next )

insert object relative to current position and indicator

Parameters

  obj | pointer to object
  pos | position indicator

Returns
  pointer to object

## ◆ prepend()

DcmObject * DcmList::prepend | ( | DcmObject * | obj | ) |

insert object at start of list

Parameters

  obj | pointer to object

Returns
  pointer to object

## ◆ remove()

DcmObject * DcmList::remove | ( |  | ) |

remove current entry from list, return element

Returns
  pointer to removed element, which is not deleted

## ◆ seek()

DcmObject * DcmList::seek | ( | E_ListPos | pos = ELP_next | ) |

seek within element in list to given position (i.e.

set current element to given position)

Parameters

  pos | position indicator

Returns
  pointer to new current object

## ◆ seek_to()

DcmObject * DcmList::seek_to | ( | unsigned long | absolute_position | ) |

seek within element in list to given element index (i.e.

set current element to given index)

Parameters

  absolute_position | position index < card()

Returns
  pointer to new current object
