IResult |
execute(IProgressListener listener)
The execute method is called after all arguments have been injected into
the query instance. |
static IResult |
execute(String className,
ISnapshot snapshot,
String labelHistogramReferenced,
String labelHistogramRetained,
String labelHistogramStronglyRetainedReferents,
IProgressListener listener)
Important: the className must point to
java.lang.ref.Reference or one of its subclasses. |

- Description copied from interface:
IQuery
- The execute method is called after all arguments have been injected into
the query instance.
Typical results are
TextResult
, CompositeResult
, SectionSpec
etc.
- Specified by:
execute
in interface IQuery
- Parameters:
listener
- Monitor to report progress and check for cancellation.
- Returns:
- The result of the query.
- Throws:
Exception
execute
public static IResult execute(String className,
ISnapshot snapshot,
String labelHistogramReferenced,
String labelHistogramRetained,
String labelHistogramStronglyRetainedReferents,
IProgressListener listener)
throws SnapshotException
- Important: the className must point to
java.lang.ref.Reference or one of its subclasses. It is not possible to
check this, as some heap dumps lack class hierarchy information.
- Throws:
SnapshotException
