InstanceFieldLoadStreamFactory
public InstanceFieldLoadStreamFactory(java.lang.String streamBaseClass)
- Constructor.
By default, Streams created by this factory
will not be marked as interesting.
The setBugPatternType() method should be called to
make the factory produce interesting streams.
- Parameters:
streamBaseClass
- the base class of the streams
produced by the factory
setBugPatternType
public InstanceFieldLoadStreamFactory setBugPatternType(java.lang.String bugPatternType)
- Set the bug pattern type reported for unclosed streams
loaded from this field. This makes the created
streams "interesting".
- Parameters:
bugPatternType
- the bug pattern type
createStream
public Stream createStream(Location location,
org.apache.bcel.generic.ObjectType type,
org.apache.bcel.generic.ConstantPoolGen cpg,
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
