Specifies whether the tree node is expandable; that is, whether there are nodes below the current level.
Type
public boolean isExpandable
Notes
The isExpandable member variable indicates whether a node is expandable, as Table 109 shows.
Type of node | Description | Value of isExpandable |
---|---|---|
Expandable | Node has child nodes | true |
Leaf (terminating) | Node does not have child nodes but is the terminating point of a branch of the source-node hierarchy | false |
Only normal-nature nodes (nodes with their polymorphicNature member variable set to NODE_NATURE_NORMAL) can have isExpandable set to true.
