Method Detail

isExpanded

boolean isExpanded()

Returns:

true if the node is expanded, this makes sense only if isLeaf() is false.

getLevel

int getLevel()

Returns:

The nesting level of the current node.
The zero value is, by convention, reserved for root nodes.

isLeaf

boolean isLeaf()

Returns:

true if the node is a leaf, which means it cannot have childs.

isSubTotal

boolean isSubTotal()

Returns:

true if the node is a node containing sub-totals, it is a special leaf case.

hasChilds

boolean hasChilds()

Returns:

true if the node has childs, it makes sense, normally, only if isLeaf() is false.
If it is not known yet, then return true.
