Interface IStep
-
All Known Subinterfaces:
-
IFilteredStep,
IStackFrame,
IThread
-
public interface IStep
Provides 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 Summary
|
boolean
|
canStepInto
()
Returns whether this element can currently perform a step into. |
boolean
|
canStepOver
()
Returns whether this element can currently perform a step over. |
boolean
|
canStepReturn
()
Returns whether this element can currently perform a step return. |
boolean
|
isStepping
()
Returns whether this element is currently stepping. |
void
|
stepInto
()
Steps into the current statement, generating RESUME
and SUSPEND events for the associated thread. |
void
|
stepOver
()
Steps over the current statement, generating RESUME
and SUSPEND events for the associated thread. |
void
|
stepReturn
()
Steps to the next return statement in the current scope,
generating RESUME and SUSPEND events for
the associated thread. |
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 stepOver call 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
DebugException
- Steps into the current statement, generating
RESUME
and SUSPEND events 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
DebugException
- Steps over the current statement, generating
RESUME
and SUSPEND events 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
DebugException
- Steps to the next return statement in the current scope,
generating
RESUME and SUSPEND events 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
