All Known Implementing Classes:

AnyMethodReturnValueStreamFactory, InstanceFieldLoadStreamFactory, IOStreamFactory, MethodReturnValueStreamFactory, StaticFieldLoadStreamFactory

public interface StreamFactory

An object that examines a Location and determines if a Stream is created there.

Method Summary

Modifier and Type	Method and Description
Stream	createStream(Location location, org.apache.bcel.generic.ObjectType type, org.apache.bcel.generic.ConstantPoolGen cpg, RepositoryLookupFailureCallback lookupFailureCallback) Determine if a Stream is created at given location.

Method Detail

createStream

Stream createStream(Location location,
                    org.apache.bcel.generic.ObjectType type,
                    org.apache.bcel.generic.ConstantPoolGen cpg,
                    RepositoryLookupFailureCallback lookupFailureCallback)

Determine if a Stream is created at given location.

Parameters:

location - the Location

type - 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 object

cpg - the ConstantPoolGen for the method

lookupFailureCallback - used to report missing classes in the class hierarchy

Returns:

a Stream created at the Location, or null if no stream is created there
