createTreeModel

public static org.apache.myfaces.trinidad.model.TreeModel createTreeModel(DataModel binding)

Create a TreeModel from a cubic binding

Parameters:

binding - cubic binding to use as basis for the TreeModel. The format is expected to have all of the columns arranged on the column edge, with the data layer as the fastest varying on that edge. Proper insert before totals must also be defined as part of the binding.

Returns:

TreeModel corresponding to the binding's data

createTreeModel

public static org.apache.myfaces.trinidad.model.TreeModel createTreeModel(java.util.Collection collection,
                                                          java.lang.String[] columns,
                                                          java.lang.String[] dataColumns,
                                                          java.lang.String[] extraCols,
                                                          oracle.adf.model.dvt.util.transform.total.AggType aggType)

Create a TreeModel from a list of property->value maps, an ordered list of columns representing the properties in the maps, a list of which columns in the maps represent data, a list of which columns are to be aggregated down in the data itself rather than as nodes in the tree, and the type of aggregation to use (SUM, etc.)

Parameters:

collection - a Collection of property/value pair Maps. Each element is a row and each property is a column and its value in that row

columns - a list of columns represented in the maps that defines the parent->child ordering of the non data columns in the TreeModel

dataColumns - a list of columns from the maps that should be used as data values in non aggregate TreeModel nodes.

extraCols - a list of columns from the maps that should be aggregated as data and not represented in the TreeModel as nodes.

aggType - the type of aggregation to use (see AggType)

Returns:

TreeModel corresponding to the Collection of Maps.

pivot

public static boolean pivot(org.apache.myfaces.trinidad.model.TreeModel tree,
            java.lang.String sourceColumn,
            java.lang.String destinationColumn,
            int pivotType)

Move the given source column from one place in the tree to another.

Parameters:

tree - TreeModel on which to operate

sourceColumn - Column to move

destinationColumn - Location at which to move sourceColumn

pivotType - Type of move to make (before, after, swap, see DataDirector pivot types)

Returns:

true if successful
