public class AtomicActorMatcher
extends TypedAtomicActor
implements GTEntity, ValueListener

A matcher to match any AtomicActor or CompositeActor that is considered as a blackbox. In the pattern of a TransformationRule, this matcher can be customized by instances of Criterion. A PortCriterion, for instance, customizes this matcher with an additional port, whose type and name can be specified. In the replacement of a TransformationRule, operations can be specified for this matcher with instances of Operation. The operations will be performed on the actor that is matched by the corresponding matcher in the pattern, and is preserved after the transformation.

Constructor Detail

AtomicActorMatcher

public AtomicActorMatcher(CompositeEntity container,
                          java.lang.String name)
                   throws IllegalActionException,
                          NameDuplicationException

Construct an atomic actor matcher to be either contained in the pattern of a TransformationRule or in the replacement.

Parameters:

container - The proposed container of this matcher.

name - The name of this matcher.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container.

NameDuplicationException - If the name coincides with an entity already in the container.

Method Detail

getCriteriaAttribute

public GTIngredientsAttribute getCriteriaAttribute()

Return the attribute that stores all the criteria for this matcher.

Specified by:

getCriteriaAttribute in interface GTEntity

Returns:

The attribute that stores all the criteria.

getDefaultIconDescription

public java.lang.String getDefaultIconDescription()

Return a string that contains the SVG icon description ("<svg>...</svg>") for this matcher. This icon description is the default icon for the matcher, which may be changed by the criteria.

Specified by:

getDefaultIconDescription in interface GTEntity

Returns:

The icon description.

getOperationsAttribute

public GTIngredientsAttribute getOperationsAttribute()

Return the attribute that stores all the operations for this matcher.

match

public boolean match(NamedObj object)

Test whether this AtomicActorMatcher can match the given object. The matching is shallow in the sense that objects contained by this matcher need not match the corresponding objects in the given object for the return result to be true. The return result is true if and only if the given object is an instance of ComponentEntity.

Specified by:

match in interface GTEntity

Parameters:

object - The NamedObj.

Returns:

Whether this AtomicActorMatcher can match the given object.

updateAppearance

Specified by:

updateAppearance in interface GTEntity

Parameters:

attribute - The attribute containing ingredients of this entity.

See Also:

GTEntityUtils.updateAppearance(GTEntity, GTIngredientsAttribute)

valueChanged

public void valueChanged(Settable settable)

React to the fact that the specified Settable has changed.

Specified by:

valueChanged in interface ValueListener

Parameters:

settable - The object that has changed value.

See Also:

GTEntityUtils.valueChanged(GTEntity, Settable)

_exportMoMLContents

protected void _exportMoMLContents(java.io.Writer output,
                                   int depth)
                            throws java.io.IOException

Write a MoML description of the contents of this object, which in this class are the attributes plus the ports. This method is called by exportMoML(). Each description is indented according to the specified depth and terminated with a newline character.

Overrides:

_exportMoMLContents in class Entity

Parameters:

output - The output to write to.

depth - The depth in the hierarchy, to determine indenting.

Throws:

java.io.IOException - If an I/O error occurs.
