public class PSDFNodeWeight
extends DIFNodeWeight

Information associated with a PSDF node. PSDFNodeWeights are objects associated with Nodes that represent PSDF nodes in Graphs. This class caches frequently-used data associated with PSDF nodes. It is also useful for representing intermediate PSDF graph representations that do not correspond to Ptolemy II models, and performing graph analyses such as quasi-static scheduling. It is intended for use with analysis/synthesis algorithms that operate on generic graph representations of PSDF models.

Constructor Detail

PSDFNodeWeight

public PSDFNodeWeight(java.lang.Object computation)

Create a PSDF node weight given a computation that is to be represented by the PSDF node. The computation may be any Object that represents a computation in some way (or null if no computation is to be represented by the node). The represented computation may, for example, be a Ptolemy II AtomicActor.

Parameters:

computation - the computation to be represented by the PSDF node.

PSDFNodeWeight

public PSDFNodeWeight()

Construct a PSDF node weight with no computation to be represented by the associated PSDF node.

Method Detail

toString

public java.lang.String toString()

Return a string representation of the PSDF node that is represented by this node weight.

Overrides:

toString in class DIFNodeWeight

Returns:

the string representation.
