Class Debugger.SingleStep

java.lang.Object
  com.sun.squawk.Debugger.SingleStep

Enclosing class:

Debugger

public static final class Debugger.SingleStep
extends Object

A SingleStep instance represents the stepping state of a thread that is currently performing a single step.

Field Summary

static int	DEFERRED The previously completed step was to a location in a class that excluded from the relevent StepEvent.
static int	HIT A step has been completed and the thread is waiting for the debugger to take some action as a result.
static int	REQUESTED The thread has been put into single stepping mode and has yet to complete a step.

Constructor Summary

Debugger.SingleStep(Offset startFO, Offset startBCI, int targetBCI, int dupBCI, int afterDupBCI, int size, int depth)
Creates a SingleStep in the REQUESTED state.

Method Summary

int	getState() Gets the stepping state
String	toString() Returns a string representation of the object.

Constructor Detail

Debugger.SingleStep

public Debugger.SingleStep(Offset startFO,
                           Offset startBCI,
                           int targetBCI,
                           int dupBCI,
                           int afterDupBCI,
                           int size,
                           int depth)

Creates a SingleStep in the REQUESTED state.

Parameters:

startFO - the offset (in bytes) from the top of the stack of the frame in which the step started

startBCI - the bytecode index of the instruction at which the step started

targetBCI - the bytecode index of the next instruction after startBCI that starts a new source line

dupBCI - the bytecode index of another instruction apart from startBCI that returns to the same line as startBCI

afterDupBCI - the bytecode index of the first instruction after dupBCI that is on a new source line

size - the granularity of the step (1 = source line, 0 = minimum possible step)

depth - the call stack depth of the step (0 = step into, 1 = step over, 2 = step out)

Method Detail

getState

public final int getState()

Gets the stepping state

toString

public String toString()

Description copied from class: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
