Class GlimpseLayoutCache<D>

java.lang.Object

com.metsci.glimpse.core.layout.GlimpseLayoutCache<D>

public class GlimpseLayoutCache<D>
extends Object

Stores the bounds of a GlimpseLayout keyed off of the sequence of nested parent GlimpseLayouts leading back to the GlimpseCanvas. If a given GlimpseLayout is rendered to the same sequence of parent GlimpseLayouts and none of the parent GlimpseLayouts have changed shape, then the layout algorithm does not need to be run, the cached LayoutBounds can be used.
