PerfDataBuffer

Class Overview

The concrete PerfDataBuffer implementation for the local: protocol for the HotSpot PerfData monitoring implementation.

This class is responsible for acquiring access to the shared memory instrumentation buffer for the target HotSpot Java Virtual Machine.

[Expand] Inherited Methods
From class sun.jvmstat.perfdata.monitor.AbstractPerfDataBuffer void createPerfDataBuffer(ByteBuffer bb, int lvmid) Create the perfdata instrumentation buffer for the given lvmid using the given ByteBuffer object as the source of the instrumentation data. Monitor findByName(String name) Find a named Instrumentation object. List<Monitor> findByPattern(String patternString) Find all Instrumentation objects with names matching the given pattern. ByteBuffer getByteBuffer() Get the ByteBuffer containing the instrumentation data. byte[] getBytes() Get a copy of the raw instrumentation data. int getCapacity() Get the capacity of the instrumentation buffer. int getLocalVmId() Get the Local Java Virtual Machine Identifier, or lvmid for the target JVM associated with this instrumentation buffer. MonitorStatus getMonitorStatus() Get a list of the inserted and removed monitors since last called.
From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
