Class AnyMethodReturnValueStreamFactory
java.lang.Object
edu.umd.cs.findbugs.detect.AnyMethodReturnValueStreamFactory
- All Implemented Interfaces:
- StreamFactory
public class AnyMethodReturnValueStreamFactory
- extends java.lang.Object
- implements StreamFactory
Factory for stream objects of a particular
base class type returned by any method.
This factory helps us keep track of streams returned
by methods; we don't want to report them, but we do
want to keep track of whether or not they are closed,
to avoid reporting unclosed streams in the same
equivalence class.

public Stream createStream(Location location,

RepositoryLookupFailureCallback lookupFailureCallback)
- Description copied from interface:
StreamFactory
- Determine if a Stream is created at given location.
- Specified by:
createStream
in interface StreamFactory
- Parameters:
location
- the Locationtype
- the ObjectType associated with the instruction at the location;
the StreamResourceTracker prescreens for TypedInstructions
that are associated with ObjectTypes, since they are
the only instructions that could conceivably create a
stream objectcpg
- the ConstantPoolGen for the methodlookupFailureCallback
- used to report missing
classes in the class hierarchy
- Returns:
- a Stream created at the Location,
or null if no stream is created there
