#include <tree_node.h>
This interface represents a node in the program tree that can be used to construct a sub-tree rooted in a AuboCap program node.
Using the ProgramModel#getRootTreeNode(ProgramNodeContribution) to obtain a root for the sub-tree, it is possible to add children. For each call to TreeNode#addChild(ProgramNode), a new TreeNode is returned, that can, in turn, act as a root for yet another sub-tree.

Add a child program node to the sub-tree.
- Parameters
-
- Returns
- Returns a TreeNode that can be used to add children to the newly added child.
- Exceptions
-
| TreeNodePtr arcs::aubo_scope::TreeNode::cutChildNode |
( |
TreeNodePtr |
child | ) |
|
Cut a child program node under in the sub-tree directly after the existing selected child node.
Shifts any subsequent nodes to positions after the newly added child.
- Parameters
-
- Returns
- Returns the TreeNode that has been cut off.
- Exceptions
-
| std::vector<TreeNodePtr> arcs::aubo_scope::TreeNode::getChildren |
( |
| ) |
|
- Returns
- a list of
TreeNode objects that represents all the children of this TreeNode (both programmatically added as well as inserted by the end user).

| ProgramNodePtr arcs::aubo_scope::TreeNode::getProgramNode |
( |
| ) |
|
- Returns
- Returns the ProgramNode at this position in the sub-tree. Can either be a built-in AuboScope program node (provided by AUBO Robots) or a AuboCap program node.
| TreeNodePtr arcs::aubo_scope::TreeNode::insertChildAfter |
( |

) |
| |
Inserts a child program node under in the sub-tree directly after the existing selected child node.
Shifts any subsequent nodes to positions after the newly added child.
- Parameters
-
- Returns
- Returns a TreeNode that can be used to add children to the newly added child.
- Exceptions
-
| TreeNodePtr arcs::aubo_scope::TreeNode::insertChildBefore |
( |
TreeNodePtr |
existingChildNode, |
|
|
ProgramNodePtr |
program_node |
|
) |
| |
Inserts a child program node in the sub-tree directly before the existing selected child node.
Shifts the selected child node and any subsequent nodes to positions after the newly added child.
- Parameters
-
- Returns
- Returns a TreeNode that can be used to add children to the newly added child.
- Exceptions
-
| bool arcs::aubo_scope::TreeNode::isInProgramTree |
( |
| ) |
|
Whether the node is in the program tree; nodes not in the program tree may have been cut or deleted.
- Returns
- Returns
true The node is in the program tree. false The node is not in the program tree; such nodes may have been cut or deleted.
| bool arcs::aubo_scope::TreeNode::isSuppressed |
( |
| ) |
|
| TreeNodePtr arcs::aubo_scope::TreeNode::locateDescendantTreeNode |
( |
ProgramNodePtr |
program_node | ) |
|
Gets a corresponding TreeNode instance for a child program node (a ProgramNode instance) in the sub-tree under this TreeNode.
This method can for instance be used to gain access to the sub-tree under a child program node encountered when iterating the sub-tree of the parent node using the ProgramNodeVisitor (or any derived sub class thereof).
- Parameters
-
| programNode | program node to get a corresponding TreeNode representation for, not null. Can either be a built-in AuboScope program node (provided by Universal Robots) or a AuboCap program node. |
- Returns
- the
TreeNode instance for the specified program node.
- Exceptions
-
| ProgramNodeNotInSubTreeException | when the program node cannot be found because it is not in the sub-tree. |
| bool arcs::aubo_scope::TreeNode::removeChild |
( |
TreeNodePtr |
program_node | ) |
|
Removes a child node from the sub-tree.
Be aware that removing the last child will trigger the insertion of an { <empty>} child node.
- Parameters
-
- Returns
- Returns
true if removed successfully. false otherwise.
- Exceptions
-
| void arcs::aubo_scope::TreeNode::setChildSequenceLocked |
( |
bool |
isChildSequenceLocked | ) |
|
Configures whether or not child nodes can be rearranged, deleted or have other nodes inserted into the child sequence by the end user.
- Parameters
-
| isChildSequenceLocked | If true then the immediate children under this TreeNode will be locked. |
| int arcs::aubo_scope::TreeNode::traverse |
( |
std::function< int(ProgramNodePtr, int, int)> |
nodeVisitor | ) |
|
This method traverses the entire sub-tree under this tree node in a depth-first fashion (this corresponds to a top-down approach in the program tree).
A node visitor is used for callbacks to the visit-overloads you choose to override. The overload called depends on the node type encountered. Override the overloads for the node types you are concerned with. All visit-methods have the program node, sibling index and depth as arguments to help filter nodes if needed.
The node visitor can be either a ProgramNodeVisitor implementation with optional overrides or a ProgramNodeInterfaceVisitor implementation. In the latter case, the ProgramNodeInterfaceVisitor#visitAs(Object, int, int) method must be implemented.
The ProgramNodeInterfaceVisitor can be used when targeting AuboCap program nodes implementing the (generic) type parameter specified in ProgramNodeInterfaceVisitor (see also ProgramNode#getAs(Class)).
Note that this method is sometimes called accept() in the Visitor software design pattern.
- Parameters
-
| nodeVisitor | the instance callbacks are made to. |
- Returns
- 0 for normal exit. non-zero for exception or error causing premature exit.
