org.das2.qds.util.ValuesTreeModel

provides a TreeModel representation of the dataset's properties.

ValuesTreeModel( QDataSet ds )

ValuesTreeModel( String prefix, QDataSet ds )

valuesTreeNode

valuesTreeNode( String prefix, javax.swing.tree.MutableTreeNode aroot, QDataSet ds, int sizeLimit ) → javax.swing.tree.MutableTreeNode

return a tree node for the values of a dataset.

Parameters

prefix - prefix added to the each node, e.g. "value("
aroot - the parent to which the nodes are added.
ds - the dataset to represent.
sizeLimit - the number of nodes to represent, e.g. 20, and ellipses (...) will represent the values not shown.

Returns:

the node (aroot) is returned.

valuesTreeNode2

valuesTreeNode2( String prefix, javax.swing.tree.TreeNode parent, QDataSet ds ) → javax.swing.tree.TreeNode

The valuesTreeNode implementation that uses MutableTreeNodes cannot scale to very large datasets, since all nodes are created immediately. This implementation only queries the dataset as children are opened, and should eventually allow for exploration of any dataset. This is not used right now in the metadata tab of Autoplot because the root node of the tree is a MutableTreeNode and all children must therefore be MutableTreeNodes.

Parameters

prefix - string prefix, a number of spaces to indent
parent - the parent node
ds - the dataset source of the values.

Returns:

the tree node
