## Detailed Description

Class implementing a document tree node cursor.

Included sub-templates are not supported by this type of cursor, i.e. the subtree that is managed by an instance of DSRIncludedTemplateTreeNode is not iterated.

## Constructor & Destructor Documentation

## DSRDocumentTreeNodeCursor() [1/3]

DSRDocumentTreeNodeCursor::DSRDocumentTreeNodeCursor | ( | const DSRDocumentTreeNodeCursor & | cursor | ) |

copy constructor

Parameters

  cursor | object to be copied

References DSRDocumentTreeNodeCursor().

## DSRDocumentTreeNodeCursor() [2/3]

DSRDocumentTreeNodeCursor::DSRDocumentTreeNodeCursor | ( | const DSRTreeNodeCursor< DSRDocumentTreeNode > & | cursor | ) |

copy constructor (for base class)

Parameters

  cursor | object to be copied

References DSRTreeNodeCursor< DSRDocumentTreeNode >::DSRTreeNodeCursor().

## DSRDocumentTreeNodeCursor() [3/3]

DSRDocumentTreeNodeCursor::DSRDocumentTreeNodeCursor | ( | DSRDocumentTreeNode * | node,
|  | const DSRPositionCounter * | position = NULL )

constructor.

See comments on DSRTreeNodeCursor<>::setCursor() method.

Parameters

  node | pointer to tree node used to initialize the cursor
  position | optional pointer to position counter that should be used to initialize the internal counter

## Member Function Documentation

## gotoMatchingNode()

virtual size_t DSRDocumentTreeNodeCursor::gotoMatchingNode | ( | const DSRDocumentTreeNodeFilter & | filter,
|  | const OFBool | searchIntoSub = OFTrue )

virtual

set internal cursor to a matching node (starting from current position).

If more than one node exists matching the given filter, the first one will be selected. Use gotoNextMatchingNode() in order to go to the next matching node.

Parameters

  filter | matching criterion based on a single or multiple filters
  searchIntoSub | flag indicating whether to search into sub-trees ("deep search") or on the current level only

Returns
  ID of the new current node if successful, 0 otherwise

## gotoNextMatchingNode()

virtual size_t DSRDocumentTreeNodeCursor::gotoNextMatchingNode | ( | const DSRDocumentTreeNodeFilter & | filter,
|  | const OFBool | searchIntoSub = OFTrue )

virtual

set internal cursor to the next matching node.

Starts from "next" node, i.e. either the first child of the current node or the first sibling following the current node.

Parameters

  filter | matching criterion based on a single or multiple filters
  searchIntoSub | flag indicating whether to search into sub-trees ("deep search") or on the current level only

Returns
  ID of the new current node if successful, 0 otherwise

## operator=() [1/2]

DSRDocumentTreeNodeCursor & DSRDocumentTreeNodeCursor::operator= | ( | const DSRDocumentTreeNodeCursor & | cursor | ) |

assignment operator

Parameters

  cursor | object to be copied

Returns
  reference to modified cursor (this object)

References DSRDocumentTreeNodeCursor().

## operator=() [2/2]

DSRDocumentTreeNodeCursor & DSRDocumentTreeNodeCursor::operator= | ( | DSRDocumentTreeNode * | node | ) |

assignment operator.

See comments on DSRTreeNodeCursor<>::setCursor() method.

Parameters

  node | node to which the cursor should be set

Returns
  reference to modified cursor (this object)
