Class 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.

                                    java.lang.String className,

        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

      • 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
