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.

protected static DwarfParser
createDwarfParser(LinuxDebugger linuxDbg, Address pc)

Returns: DwarfParser instance for the PC, null if native library relates to the pc not found.

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.

createDwarfParserback to summary
protected static DwarfParser createDwarfParser(LinuxDebugger linuxDbg, Address pc)
Returns:DwarfParser

DwarfParser instance for the PC, null if native library relates to the pc not found.

Exceptions
DebuggerException:
if DWARF processing is failed. For example: pc is not covered in this DWARF, Common Information Entry (CIE) has language personality routine and/or Language Data Area (LSDA).
