Figure 8-19 Reference Sub-Trees by Size Visualizer – Attributes table
NOTE: The symbol // indicates a reference for which memory occupied has already been

node of this particular reference.
Object and Primitive Value Tables
For binary heap dump files, the tables on the right side of this visualizer display object and
primitive values for any selected node object in the tree:
• The Attributes table shows the names and values of the non-static fields in the node object.
• The Statics table shows the names and values of the static fields in the node object.
Notice that the table content changes as you choose different tree nodes. If you click the tree root
node, all root node information is shown in the Attributes table. If the table size is not large
enough vertically, use the scroll bar to view more data.
NOTE: The values of fields and arrays of primitive types are available only for binary heap
dump files, not for ASCII heap dump files.
The Attributes and Statics tables have 3 columns: Type, Name, and Value. The type of data in
the Value column will differ depending on the data type (see Figure 8-19 for the examples given
below):
• For the eight primitive types (boolean, byte, char, short, int, long, float, and
double), the Value column shows the real value. For example, the Attributes table for the
