Class ImageProfiles

java.lang.Object

com.oracle.svm.core.ImageProfiles

public abstract class ImageProfiles
extends Object

Access to collected image profiles. This class provides an API - e.g. ImageProfiles.dumpProfiles() method that can be called any time to obtain information about the currently collected profiling data, if any. This class also serves as an SPI - subclasses shall override the ImageProfiles.computeProfiles() method to return their collected image profiles. There can be at most single implementation of this type, registered in ImageSingletons.
