类 MemoryWarningSystem

java.lang.Object

soot.jimple.infoflow.memory.MemoryWarningSystem

public class MemoryWarningSystem
extends Object

Notification system that triggers a callback when the JVM is about to run out of memory. Inspired by code from http://www.javaspecialists.eu/archive/Issue092.html. Be careful, because memory allocation is usually fast. There might not be a lot of time left to perform corrective measures if the warning threshold is reached.

finalize

protected void finalize()
                 throws Throwable

覆盖:

finalize 在类中 Object

抛出:

Throwable

addListener

public void addListener(MemoryWarningSystem.OnMemoryThresholdReached listener)

Adds a listener that is called when the memory usage threshold defined using setWarningThreshold() has been reached

参数:

listener - The listener to add

findTenuredGenPool

public static MemoryPoolMXBean findTenuredGenPool()

Tenured Space Pool can be determined by it being of type HEAP and by it being possible to set the usage threshold.

setWarningThreshold

public void setWarningThreshold(double percentage)

Sets the one single global warning threshold for memory usage. If at least the given fraction of the overall tenured pool is in use, the registered hanlders will be invoked.

参数:

percentage -

close

public void close()

Closes this warning system instance. It will no longer notify any listeners of memory shortages.
