Method Summary

Modifier and TypeMethod and Description
public ClosestSymbol
closestSymbolToPC()

Overrides sun.jvm.hotspot.debugger.cdbg.basic.BasicCFrame.closestSymbolToPC.

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

For the loadobject in which the PC lies, fetch the name of the closest exported symbol and the distance of the PC to that symbol.

public Address
localVariableBase()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Gets the base pointer in this frame from which local variable offsets in the debug info are based.

public Address
pc()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Get the program counter of this frame

public CFrame
sender(ThreadProxy thread)

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Returns null when no more frames on stack

public CFrame
sender(ThreadProxy thread, Address nextSP, Address nextFP, Address nextPC)

Overrides default sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Find sender frame with given FP and PC

public Frame
toFrame()

Overrides default sun.jvm.hotspot.debugger.cdbg.CFrame.toFrame.

Get Frame instance assosiated with this CFrame.

closestSymbolToPCback to summary
public ClosestSymbol closestSymbolToPC()

Overrides sun.jvm.hotspot.debugger.cdbg.basic.BasicCFrame.closestSymbolToPC.

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.closestSymbolToPC.

For the loadobject in which the PC lies, fetch the name of the closest exported symbol and the distance of the PC to that symbol. Returns null if the PC was not within any of the loadobjects of the target process. FIXME: specify whether this is mangled/demangled.

localVariableBaseback to summary
public Address localVariableBase()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.localVariableBase.

Gets the base pointer in this frame from which local variable offsets in the debug info are based. Typically this is the base-of-frame pointer (RBP on amd64, FP/I6 on SPARC).

pcback to summary
public Address pc()

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.pc.

Get the program counter of this frame

senderback to summary
public CFrame sender(ThreadProxy thread)

Implements sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Doc from sun.jvm.hotspot.debugger.cdbg.CFrame.sender.

Returns null when no more frames on stack
