extends java.lang.Object

Constraints for a component in the model.

The model component can be an object of any Ptolemy class (e.g. ASTPtRootNode, Sink, Entity, and FSMActor). A model component, in turn, may have one or multiple property-able objects. Each constraint is relevant to a property-able object. For example, the PropertyAdapter associated with an actor may have each of its IOPorts as property-able.

A property-able object is an object that can be annotated with a Property object. Users can define different Property classes as part of their use-case definition.

Every PropertyAdapter is associated a property solver. PropertyAdapters support hierarchical structuring. They may have downward links to sub-adapters. This is helpful to construct PropertyAdapter for hierarchical component in the model. For example, a PropertyAdapter for the CompositeActor have all the contained actors' adapters as its sub-adapters.

A PropertyAdapter supports manual annotation. Users can define their own annotation evaluator to evaluate property expressions and/or constraints.

Field Detail

_annotationEvaluator

protected ParseTreeAnnotationEvaluator _annotationEvaluator

The annotation evaluator.

_solver

protected OntologySolver _solver

The associated ontology solver.

Constructor Detail

OntologyAdapter

public OntologyAdapter()

Method Detail

getComponent

public java.lang.Object getComponent()

Return the associated component object.

Returns:

The associated component.

See Also:

setComponent(java.lang.Object)

getContainerEntity

public Entity getContainerEntity(ASTPtRootNode node)

Return the container entity for the specified ASTPtRootNode.

Parameters:

node - The specified ASTPtRootNode.

Returns:

The container entity for the specified ASTPtRootNode.

getName

public java.lang.String getName()

Return the name of the PropertyAdapter. In this base class, return the concatenation of the prefix "Adapter_" and the string representation of the component object. This method does not guarantee uniqueness.

Returns:

The name of the PropertyAdapter.

getPropertyables

public java.util.List<java.lang.Object> getPropertyables()

Return a list of property-able NamedObj contained by the component. All ports and parameters are considered property-able.

Returns:

The list of property-able named object.

getSolver

public OntologySolver getSolver()

Return The PropertySolver that uses this adapter.

Returns:

The PropertySolver that uses this adapter.

reinitialize

public void reinitialize()
                  throws IllegalActionException

Reset and initialize the PropertyAdapter. This clears any cached states and the resolved properties of the property-able objects. This call is recursive, so every sub-adapter will be reset and initialized after the call.

Throws:

IllegalActionException - Thrown if getPropertyables() throws it.

setComponent

public void setComponent(java.lang.Object component)

Associate this PropertyAdapter with the specified component.

Parameters:

component - The specified component.

See Also:

getComponent()

setEquals

public void setEquals(java.lang.Object object,
                      Concept property)

Set the property of specified object equal to the specified property.

Parameters:

object - The specified object.

property - The specified property.

toString

public java.lang.String toString()

Return the string representation of the PropertyAdapter.

Overrides:

toString in class java.lang.Object

Returns:

The string representation of the PropertyAdapter.

_annotationEvaluator

protected abstract ParseTreeAnnotationEvaluator _annotationEvaluator()

Create a new ParseTreeAnnotationEvaluator that is tailored for the ontology. This class parses the user-defined ontology annotations in the model containing the OntologySolver.

Returns:

A new ParseTreeAnnotationEvaluator.

_getASTNodeAdapters

protected java.util.List<OntologyAdapter> _getASTNodeAdapters()
                                                       throws IllegalActionException

Return the list of PropertyAdapters for ASTPtRootNodes. These ASTPtRootNodes are nodes of the parse tree constructed from parsing the expression of every property-able Attribute.

Returns:

The list of PropertyAdapters for ASTPtRootNodes.

Throws:

IllegalActionException - If the AST expression is not parseable

_getAttributeParseTrees

protected java.util.List<ASTPtRootNode> _getAttributeParseTrees()
                                                         throws IllegalActionException

Return the list of parse trees for all settable Attributes of the component.

Returns:

The list of ASTPtRootNodes.

A property-able Attribute is a StringAttribute with the name "guardTransition", a StringAttribute in an Expression actor, a StringAttribute with the name "expression" or a Variable with full visibility. However, Variables with certain names are excluded.

Returns:

The list of property-able Attributes.

_getSinkPortList

protected static java.util.List<IOPort> _getSinkPortList(IOPort port)

Return the list of receiving (down-stream) ports that are connected to the specified port. This treats every port as an opaque port.

_getSourcePortList

protected static java.util.List<IOPort> _getSourcePortList(IOPort port)

Return the list of sending (up-stream) ports that are connected to the specified port. This treats every port as an opaque port.

Returns:

The list of sending ports.
