Class StaticFieldLoadStreamFactory

java.lang.Object
  extended by edu.umd.cs.findbugs.detect.StaticFieldLoadStreamFactory
All Implemented Interfaces:
StreamFactory

public class StaticFieldLoadStreamFactory
extends java.lang.Object
implements StreamFactory

Stream factory for streams created by loading a value from a static field. This is mainly to handle System.in, System.out, and System.err.

StaticFieldLoadStreamFactory

public StaticFieldLoadStreamFactory(java.lang.String streamBaseClass,
                                    java.lang.String className,
                                    java.lang.String fieldName,
                                    java.lang.String fieldSig)
Constructor. Created Stream objects will be marked as uninteresting.

Parameters:
streamBaseClass - the base class of the stream objects created by the factory
className - name of the class containing the static field
fieldName - name of the static field
fieldSig - signature of the static field
Method Detail

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 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
