Method Detail

getText

java.lang.String getText()

Returns the text of the tree map node

getChildren

java.util.List<ITreeMapNode<T>> getChildren()

Returns the list of children of this node. This usually is a readonly list.

getArea

double getArea()

Returns the area of this node including all subnodes.

getColor

java.awt.Color getColor()

Returns the base color used for drawing this node.

getPatternColor

java.awt.Color getPatternColor()

Returns the color used for drawing the pattern (if any) of this node.

getDrawingPattern

IDrawingPattern getDrawingPattern()

Returns the pattern used for drawing the node (may be null to use no pattern).

getLayoutRectangle

java.awt.geom.Rectangle2D getLayoutRectangle()

Returns the rectangle this node was layouted into. If the tree was not yet layouted, this may be null, otherwise it should be the value set by setLayoutRectangle(Rectangle2D).

setLayoutRectangle

void setLayoutRectangle(java.awt.geom.Rectangle2D rect)

Sets the rectangle this node should be layouted into.

getTooltipId

java.lang.String getTooltipId()

Get displayable name of the node.

getTooltipKeys

java.util.List<java.lang.String> getTooltipKeys()

Returns keys for structured displayable data.

getTooltipValue

java.lang.Object getTooltipValue(java.lang.String key)

Returns the value to be displayed for a single key.

recalculateAreaAggregates

double recalculateAreaAggregates()

Re-calculates the aggregated area for this node and for all of its children. This is required after filtering treemap nodes.

Returns:

the new area for this node.
