Class InlinePortTransformer

          ptolemy.copernicus.java.InlinePortTransformer

All Implemented Interfaces:

soot.HasPhaseOptions

public class InlinePortTransformer
extends soot.SceneTransformer
implements soot.HasPhaseOptions

A Transformer that is responsible for inlining the communication between ports. The connections between the ports are taken from the model specified in the constructor of this transformer. FIXME: currently we try to speed things up if the buffersize is only one by removing the index update overhead. Note that there are other optimizations that can be made here (for instance, if we can statically determine all the channel references (which is trivially true if there is only one channel), then there is no need to have the index or portbuffer arrays.

Method Detail

v

public static InlinePortTransformer v(CompositeActor model)

Return an instance of this transformer that will operate on the given model. The model is assumed to already have been properly initialized so that resolved types and other static properties of the model can be inspected.

getBufferFieldName

public static java.lang.String getBufferFieldName(TypedIORelation relation,
                                                  int channel,
                                                  Type type)

Return the name of the field that is created to represent the given channel of the given type of the given relation.

getPortInliner

public static PortInliner getPortInliner(CompositeActor model)

Return the port inliner for the given model.

setPortInliner

public static void setPortInliner(CompositeActor model,
                                  PortInliner inliner)

Set the port inliner for the given model. This method is expected to be called by the Director inliner when when a decision is made about how to inline ports.

getPhaseName

public java.lang.String getPhaseName()

Specified by:

getPhaseName in interface soot.HasPhaseOptions

getDefaultOptions

public java.lang.String getDefaultOptions()

Specified by:

getDefaultOptions in interface soot.HasPhaseOptions

getDeclaredOptions

public java.lang.String getDeclaredOptions()

Specified by:

getDeclaredOptions in interface soot.HasPhaseOptions

internalTransform

protected void internalTransform(java.lang.String phaseName,
                                 java.util.Map options)

Specified by:

internalTransform in class soot.SceneTransformer

getPortValue

public static TypedIOPort getPortValue(soot.SootMethod method,
                                       soot.Local local,
                                       soot.Unit location,
                                       soot.toolkits.scalar.LocalDefs localDefs,
                                       soot.toolkits.scalar.LocalUses localUses)

Attempt to determine the constant value of the given local, which is assumed to have a variable type. Walk backwards through all the possible places that the local may have been defined and try to symbolically evaluate the value of the variable. If the value can be determined, then return it, otherwise return null.
