Object Reference Graph data commands

The following tables describe the filtering and highlighting commands you can use to analyze data in the Object Reference Graph view and the Object Details view.

Expand/Collapse commands

Expand/Collapse commands show or hide descendants of a selected node. These commands do not affect the counts that are displayed for nodes.

Command	Description
Expand Immediate Descendants	Expands only the immediate descendants of the selected node.
Expand All Descendants	Expands all descendants of the selected node.
Collapse All Descendants	Collapses all descendants of the selected node.
Show All Nodes	Shows all nodes in the graph.
Undo Last Expand/Collapse Operation	Undoes the last operation.
Reset to GC Roots	Undoes all expand and collapse operations; does not change current filter settings.

Subtree commands

Subtree commands operate on a specific node and all its descendants. These commands can affect the counts that are displayed for nodes.

Command	Description
Focus on Subtree	Focuses on the selected node and its descendants only. All other nodes are hidden.
Hide Subtree	Hides the selected node and all its descendants. The parent nodes inherit the counts of the hidden nodes.
Delete Subtree	Deletes the selected node and all its descendants. The parent nodes do not inherit the counts of the deleted nodes.
Undo Last Subtree Operation	Undoes the last operation.
Reset to Root	Undoes all subtree operations; does not change current filter settings.

Filter commands

Filter commands operate on an object, or all objects in a class or package. These commands can affect the counts that are displayed for nodes.

Command	Description
Delete Object	Deletes the selected node. Parent nodes inherit all descendant nodes and their counts (excluding the counts of the deleted node).
Hide Object	Hides the selected node. Parent nodes inherit all descendant nodes and their counts (including the counts of the hidden node).
Delete Class	Deletes all nodes in the selected node's class. Parent nodes inherit all descendant nodes and their counts (excluding the counts of the deleted nodes).
Hide Class	Hides all nodes in the selected node's class. Parent nodes inherit all descendant nodes and their counts (including the counts of the hidden nodes).
Delete Package	Deletes all nodes in the selected node's package. Parent nodes inherit all descendant nodes and their counts (excluding the counts of the deleted nodes).
Hide Package	Hides all nodes in the selected node's package. Parent nodes inherit all descendant nodes and their counts (including the counts of the hidden nodes).
Group Objects	Groups objects that are similar to the selected node. All objects of the same class are collapsed into a single node. The arcs from the parent nodes are also grouped. The count for a grouped node is the sum of the counts for all of the individual nodes in the group. This is the default mode.
Ungroup Object	Expands the selected grouped node into individual instance nodes. Each individual node is treated like a separate node.
Undo Last Filter Operation	Undoes the last filter operation
Reset to default	Resets all nodes to the default state.

Highlight commands

Highlight commands highlight nodes and connecting arcs based upon selection criteria.

Criterion	Description
None	Removes highlighting from all nodes and arcs.
Top 10 Count	Highlights the top 10 nodes by number of instances.
Top 10 Size	Highlights the top 10 nodes by size in bytes.
Top 10 References	Highlights the top ten nodes by number of references to other nodes.
Top 10 Referees	Highlights the top ten nodes by number of referees.
Descendants	Highlights all descendants of the selected node.
Top Immediate Descendants	Highlights the top 10 immediate descendants with the largest size.
Parents	Highlights all parent nodes of the selected node.
Immediate Parents	Highlights only immediate parent nodes of the selected node.
GC Roots	Highlights all objects that are marked by the JVM as GC root objects.
Objects with Source	Highlights nodes for which source code is available.
Objects with Hidden Objects	Highlights nodes that reference hidden nodes.
