Implements abstract sun.jvm.hotspot.runtime.Frame.addressOfSavedReceiver.

cloneback to summary
public Object clone()

Implements abstract sun.jvm.hotspot.runtime.Frame.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression: 

x.clone() != x
will be true, and that the expression: 
x.clone().getClass() == x.getClass()
will be true, but these are not absolute requirements. While it is typically the case that: 
x.clone().equals(x)
will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

getInterpreterFrameBCIback to summary
public int getInterpreterFrameBCI()

Implements abstract sun.jvm.hotspot.runtime.Frame.getInterpreterFrameBCI.

Doc from sun.jvm.hotspot.runtime.Frame.getInterpreterFrameBCI.

Byte code index. In the underlying frame, what is actually stored is a byte code pointer (BCP), which is converted to a BCI and back by the GC when methods are moved. In this system, interior pointers are not allowed, so we must make the access to the interpreter frame's BCI atomic with respect to GC. This may mean implementation with an underlying call through native code into the VM or a magic sequence in the compiler. (FIXME)

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
hasSenderPDback to summary
protected boolean hasSenderPD()

Implements abstract sun.jvm.hotspot.runtime.Frame.hasSenderPD.

Doc from sun.jvm.hotspot.runtime.Frame.hasSenderPD.

Platform-dependent query indicating whether this frame has a sender. Should return true if it is possible to call sender() at all on this frame. (This is currently only needed for the debugging system, if a stack trace is attempted for a Java thread which has no Java frames, i.e., the signal thread; we have to know to stop traversal at the bottom frame.)
