Class TransientSingletonConfigurableAttribute

java.lang.Object

ptolemy.kernel.util.NamedObj

ptolemy.kernel.util.Attribute

ptolemy.kernel.util.ConfigurableAttribute

ptolemy.kernel.util.TransientSingletonConfigurableAttribute

All Implemented Interfaces:

java.lang.Cloneable, Changeable, Configurable, Debuggable, DebugListener, Derivable, ModelErrorHandler, MoMLExportable, Moveable, Nameable, Settable, Singleton

Deprecated.

Use SingletonConfigurableAttribute instead with setPersistent(false).

@Deprecated
public class TransientSingletonConfigurableAttribute
extends ConfigurableAttribute
implements Singleton

This class is a nonpersistent configurable singleton attribute. By "nonpersistent" we mean that it does not export MoML. A major application of this class is to define a default icon description. An icon description is XML code in the SVG (scalable vector graphics) schema, set in a configure element in MoML.

Constructor Detail

TransientSingletonConfigurableAttribute

public TransientSingletonConfigurableAttribute()

Deprecated.

Construct a new attribute with no container and an empty string as its name. Add the attribute to the workspace directory. Increment the version number of the workspace.

TransientSingletonConfigurableAttribute

public TransientSingletonConfigurableAttribute(Workspace workspace)

Deprecated.

Construct a new attribute with no container and an empty string as a name. You can then change the name with setName(). If the workspace argument is null, then use the default workspace. Add the attribute to the workspace directory. Increment the version number of the workspace.

Parameters:

workspace - The workspace that will list the attribute.

TransientSingletonConfigurableAttribute

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

Deprecated.

Construct an attribute with the given container and name. If an attribute already exists with the same name as the one specified here, and of class SingletonConfigurableAttribute, then that attribute is removed before this one is inserted in the container.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute cannot be contained by the proposed container.

NameDuplicationException - If the container already has an attribute with this name, and the class of that container is not SingletonConfigurableAttribute.

Method Detail

setContainer

public void setContainer(NamedObj container)
                  throws IllegalActionException,
                         NameDuplicationException

Deprecated.

Remove any previous attribute in the container that has the same name as this attribute, and then call the base class method to set the container. If the container is not in the same workspace as this attribute, throw an exception. If this attribute is already contained by the NamedObj, do nothing. If the attribute already has a container, remove this attribute from its attribute list first. Otherwise, remove it from the directory of the workspace, if it is there. If the argument is null, then remove this attribute from its container. It is not added to the workspace directory, so this could result in this object being garbage collected.

Note that since an Attribute is a NamedObj, it can itself have attributes. However, recursive containment is not allowed, where an attribute is an attribute of itself, or indirectly of any attribute it contains.

This method is write-synchronized on the workspace and increments its version number.

Overrides:

setContainer in class Attribute

Parameters:

container - The container to attach this attribute to.

Throws:

IllegalActionException - If this attribute is not of the expected class for the container, or it has no name, or the attribute and container are not in the same workspace, or the proposed container would result in recursive containment.

NameDuplicationException - If the container already has an attribute with the name of this attribute that is of class SingletonConfigurableAttribute.
