Class TextBlobCache

java.lang.Object

icyllis.arc3d.granite.TextBlobCache

public final class TextBlobCache
extends Object

TextBlobCache reuses data from previous drawing operations using multiple criteria to pick the best data for the draw. In addition, it provides a central service for managing resource usage through a weak reference.

The draw data is stored in a three-tiered system. The first tier is keyed by the TextBlob's identity. The second tier uses the TextBlobCache.FeatureKey to get a general match for the draw. The last tier queries each sub run using canReuse to determine if each sub run can handle the drawing parameters.
