public Interface DebugEvent

Known Direct Implementers: sun.jvm.hotspot.debugger.cdbg.basic.BasicDebugEvent
Imports: sun.jvm.hotspot.debugger.*

Describes in an abstract sense the kind of debug events which may be received from the target process. On UNIX platforms these are typically signals intercepted via ptrace or some other mechanism, while on Windows they are usually exceptions. Also describes certain types of events like loading and unloading of DSOs/DLLs ("LoadObjects").

Nested and Inner Type Summary

public static class	DebugEvent.Type

Method Summary

Modifier and Type	Method and Description
public Address	getAddress() For ACCESS_VIOLATION events, returns the address at which the fault occurred.
public Address	getPC() For BREAKPOINT, SINGLE_STEP, and ACCESS_VIOLATION events, returns the program counter at which the event occurred.
public ThreadProxy	getThread() Retrieves the ThreadProxy for the thread on which the event occurred.
public DebugEvent.Type	getType() The type of this debug event; BREAKPOINT, SINGLE_STEP, etc.
public String	getUnknownEventDetail() For UNKNOWN events, may return a detail message or may return null.
public boolean	getWasWrite() For ACCESS_VIOLATION events, indicates whether the fault occurred on a write (vs. a read).

Method Detail

getAddress	back to summary
public Address getAddress() For ACCESS_VIOLATION events, returns the address at which the fault occurred. For LOADOBJECT_LOAD and LOADOBJECT_UNLOAD events, returns the base address of the loadobject in the target process's address space. For other types of events returns an undefined value.

getPC	back to summary
public Address getPC() For BREAKPOINT, SINGLE_STEP, and ACCESS_VIOLATION events, returns the program counter at which the event occurred. For other types of events returns an undefined value.

getThread	back to summary
public ThreadProxy getThread() Retrieves the ThreadProxy for the thread on which the event occurred. This is always present.

getType	back to summary
public DebugEvent.Type getType() The type of this debug event; BREAKPOINT, SINGLE_STEP, etc.

getUnknownEventDetail	back to summary
public String getUnknownEventDetail() For UNKNOWN events, may return a detail message or may return null. For other types of events returns an undefined value.

getWasWrite	back to summary
public boolean getWasWrite() For ACCESS_VIOLATION events, indicates whether the fault occurred on a write (vs. a read). For other types of events returns an undefined value.
