Interface IStep
-
- All Known Subinterfaces:
IFilteredStep,IStackFrame,IThread
public interface IStepProvides the ability to step into, over, and return from the current execution location. Implementations must be non-blocking.Implementations should honor step filter settings in their associated debug target, as defined by
IStepFilters.Clients may implement this interface.

Method Detail
-
canStepInto
boolean canStepInto()
Returns whether this element can currently perform a step into.- Returns:
- whether this element can currently perform a step into
-
canStepOver
boolean canStepOver()
Returns whether this element can currently perform a step over.- Returns:
- whether this element can currently perform a step over
-
canStepReturn
boolean canStepReturn()
Returns whether this element can currently perform a step return.- Returns:
- whether this element can currently perform a step return
-
isStepping
boolean isStepping()
Returns whether this element is currently stepping.For example, a thread is considered to be stepping after the
stepOvercall until the step over is completed, a breakpoint is reached, an exception is thrown, or the thread or debug target is terminated.- Returns:
- whether this element is currently stepping
-
stepInto
void stepInto() throws DebugExceptionSteps into the current statement, generatingRESUMEandSUSPENDevents for the associated thread. Can only be called when the associated thread is suspended. Implementations must implement stepping as non-blocking.- Throws:
DebugException- on failure. Reasons include:- TARGET_REQUEST_FAILED - The request failed in the target
- NOT_SUPPORTED - The capability is not supported by the target
-
stepOver
void stepOver() throws DebugExceptionSteps over the current statement, generatingRESUMEandSUSPENDevents for the associated thread. Can only be called when the associated thread is suspended. Implementations must implement stepping as non-blocking.- Throws:
DebugException- on failure. Reasons include:- TARGET_REQUEST_FAILED - The request failed in the target
- NOT_SUPPORTED - The capability is not supported by the target
-
stepReturn
void stepReturn() throws DebugExceptionSteps to the next return statement in the current scope, generatingRESUMEandSUSPENDevents for the associated thread. Can only be called when the associated thread is suspended. Implementations must implement stepping as non-blocking.- Throws:
DebugException- on failure. Reasons include:- TARGET_REQUEST_FAILED - The request failed in the target
- NOT_SUPPORTED - The capability is not supported by the target
