getProperties
Description copied from interface:Algorithm
Properties for storing layout algorithm specific options.- Specified by:
getProperties
in interfaceAlgorithm
- Overrides:
getProperties
in classAbstractAlgorithm
- Returns:
- the specific properties of this algorithm
-
breadthFirstLayout
public boolean breadthFirstLayout(com.macrofocus.geom.Shape shape, MutableTreeMapNode parent, MutableTreeMapNode[] children, double sumSize, int horizontalVanishingPoint, int verticalVanishingPoint, TreeMapWorker worker) Arrange the items in the given array to fill the given shape. This is called during the first pass, while traversing the tree top down.- Parameters:
shape
- the current rectangle being divided.parent
- the parent node.children
- the items to map.sumSize
- the size of the parent.worker
- the worker thread- Returns:
- true if the layout has been cancelled, false otherwise
-
isCompatible
public boolean isCompatible(com.macrofocus.geom.Shape shape) Description copied from interface:Algorithm
Indicates whether the layout algorithm can handle the given geometry of its parent- Parameters:
shape
- the geometry of its parent- Returns:
- true if it can lay out the children using the specified geometrical shape
