instanceOf

public boolean instanceOf(ISnapshot snapshot,
 int o,
 String className)
                   throws SnapshotException

Instanceof test which works for simple objects and arrays

Parameters:

snapshot -

o - the object to be tested

className - is an instance of this class?

Returns:

true if an instance

Throws:

SnapshotException

instanceOf

public boolean instanceOf(ISnapshot snapshot,
 IClass cls,
 String className)
                   throws SnapshotException

Instanceof test which works for simple object and array types

Parameters:

snapshot -

cls -

className -

Returns:

true if an instance

Throws:

SnapshotException

anyInstances

public boolean anyInstances(ISnapshot snapshot,
 String cn)
                     throws SnapshotException

Throws:

SnapshotException

anySubInstances

public boolean anySubInstances(IClass cls)

unsuitableSubjects

public boolean unsuitableSubjects(QueryDescriptor query,
 List<IContextObject> menuContext)

See if the menuContext cannot possibly satisfy the requirements of the query. Needs to be reasonably efficient, so if the calculation would take too long then it is okay to return false.

Parameters:

query -

menuContext -

Returns:

true if the menuContext is unsuitable.
