Interface IThread

All Superinterfaces:
IAdaptable, IDebugElement, IStep, ISuspendResume, ITerminate
public interface IThread extends IDebugElement, ISuspendResume, IStep, ITerminate
A thread is a sequential flow of execution in a debug target. A thread contains stack frames. Stack frames are only available when the thread is suspended, and are returned in top-down order. Minimally, a thread supports the following:
  • suspend/resume
  • stepping
  • terminate

Clients may implement this interface.

    • getStackFrames

      IStackFrame[] getStackFrames() throws DebugException
      Returns the stack frames contained in this thread. An empty collection is returned if this thread contains no stack frames, or is not currently suspended. Stack frames are returned in top down order.
      Returns:
      a collection of stack frames
      Throws:
      DebugException - if this method fails. Reasons include:
      • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
      Since:
      2.0

    • hasStackFrames

      boolean hasStackFrames() throws DebugException
      Returns whether this thread currently contains any stack frames.
      Returns:
      whether this thread currently contains any stack frames
      Throws:
      DebugException - if this method fails. Reasons include:
      • Failure communicating with the debug target. The DebugException's status code contains the underlying exception responsible for the failure.
      Since:
      2.0

    • getPriority

      int getPriority() throws DebugException
      Returns the priority of this thread. The meaning of this number is operating-system dependent.
      Returns:
      thread priority
      Throws:
      DebugException - if this method fails. Reasons include:
      • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.

    • getTopStackFrame

      IStackFrame getTopStackFrame() throws DebugException
      Returns the top stack frame or null if there is currently no top stack frame.
      Returns:
      the top stack frame, or null if none
      Throws:
      DebugException - if this method fails. Reasons include:
      • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.

    • getName

      String getName() throws DebugException
      Returns the name of this thread. Name format is debug model specific, and should be specified by a debug model.
      Returns:
      this thread's name
      Throws:
      DebugException - if this method fails. Reasons include:
      • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.

    • getBreakpoints

      IBreakpoint[] getBreakpoints()
      Returns the breakpoints that caused this thread to suspend, or an empty collection if this thread is not suspended or was not suspended by a breakpoint. Usually a single breakpoint will be returned, but this collection can contain more than one breakpoint if two breakpoints are at the same location in a program.
      Returns:
      the collection of breakpoints that caused this thread to suspend
