public class AttributeMatcher
extends Attribute
implements GTEntity

A matcher to match any attribute. In the pattern of a TransformationRule, this matcher can be customized by instances of Criterion. In the replacement of a TransformationRule, operations can be specified for this matcher with instances of Operation. The operations will be performed on the attribute that is matched by the corresponding matcher in the pattern, and is preserved after the transformation.

Field Detail

criteria

public GTIngredientsAttribute criteria

The attribute containing all the criteria in a list (GTIngredientList).

editorFactory

public GTIngredientsEditor.Factory editorFactory

The editor factory for ingredients in this matcher.

operations

public GTIngredientsAttribute operations

The attribute containing all the operations in a list (GTIngredientList).

patternObject

public PatternObjectAttribute patternObject

The attribute that specifies the name of the corresponding entity in the pattern.

Constructor Detail

AttributeMatcher

public AttributeMatcher(NamedObj container,
                        java.lang.String name)
                 throws IllegalActionException,
                        NameDuplicationException

Construct an attribute 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.

Specified by:

getOperationsAttribute in interface GTEntity

Returns:

The attribute that stores all the operations.

getPatternObjectAttribute

public PatternObjectAttribute getPatternObjectAttribute()

Return the attribute that stores the name of the corresponding entity in the pattern of the same TransformationRule, if this entity is in the replacement, or null otherwise.

Specified by:

getPatternObjectAttribute in interface GTEntity

Returns:

The attribute that stores the name of the corresponding entity.

See Also:

labelSet()

labelSet

public java.util.Set<java.lang.String> labelSet()

Return the set of names of ingredients contained in this entity that can be resolved.

Specified by:

labelSet in interface GTEntity

Returns:

The set of names.

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

public void updateAppearance(GTIngredientsAttribute attribute)

Do nothing. The appearance of an AttributeMatcher is not updated with change of the criteria or operations.

Specified by:

updateAppearance in interface GTEntity

Parameters:

attribute - The attribute containing ingredients of this entity.
