Detailed Description

Class managing a tree of nodes.

Definition at line 100 of file dsrtree.h.

Member Function Documentation

virtual size_t DSRTree::addNode ( DSRTreeNode node,
const E_AddMode  addMode = AM_afterCurrent 
)
virtual

add new node to the current one.

Please note that no copy of the given node is created. Therefore, the node should be created with new() - do not use a reference to a local variable. If the node could be added successfully the cursor is set to it automatically.

Parameters
nodepointer to the new node to be added
addModeflag specifying at which position to add the new node. (AM_afterCurrent, AM_beforeCurrent, AM_belowCurrent)
Returns
ID of the new added node if successful, 0 otherwise

Reimplemented in DSRDocumentTree.

DSRTreeNode* DSRTree::getRoot ( ) const
inlineprotected

get pointer to root node

Returns
pointer to root node, might be NULL (empty tree)

Definition at line 176 of file dsrtree.h.

References RootNode.

size_t DSRTree::gotoNode ( const size_t  searchID,
const OFBool  startFromRoot = OFTrue 
)

set internal cursor to specified node

Parameters
searchIDID of the node to set the cursor to
startFromRootflag indicating whether to start from the root node or the current one
Returns
ID of the new current node if successful, 0 otherwise
size_t DSRTree::gotoNode ( const OFString reference,
const OFBool  startFromRoot = OFTrue 
)

set internal cursor to specified node

Parameters
referenceposition string of the node to set the cursor to. (the format is e.g. "1.2.3" for the third child of the second child of the first node - see DSRTreeNodeCursor).
startFromRootflag indicating whether to start from the root node or the current one
Returns
ID of the new current node if successful, 0 otherwise
size_t DSRTree::gotoRoot ( )

set internal cursor to root node

Returns
ID of root node if successful, 0 otherwise
OFBool DSRTree::isEmpty ( ) const

check whether tree has any nodes

Returns
OFTrue if tree is empty, OFFalse otherwise
virtual size_t DSRTree::removeNode ( )
virtual

remove current node from tree.

Please note that not only the specified node but also all of its child nodes are removed from the tree and then deleted. The cursor is set automatically to a new valid position.

Returns
ID of the node which became the current one after deletion, 0 if an error occured or the tree is now empty.

Reimplemented in DSRDocumentTree.
