Constructor Detail

PatternObjectAttribute

public PatternObjectAttribute()

Construct an attribute in the default workspace with an empty string as its name. The object is added to the directory of the workspace. Increment the version number of the workspace.

PatternObjectAttribute

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

Construct an attribute with the given name contained by the specified container. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. The object is added to the directory of the workspace if the container is null. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

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

PatternObjectAttribute

public PatternObjectAttribute(Workspace workspace)

Construct an attribute in the specified workspace with an empty string as a name. The object is added to the directory of the workspace. Increment the version number of the workspace.

Parameters:

workspace - The workspace that will list the attribute.

Method Detail

valueChanged

public void valueChanged(Settable settable)

Update the appearance of the container when the value of this attribute is changed.

Specified by:

valueChanged in interface ValueListener

Parameters:

settable - The changed attribute.

_init

private void _init()

Initialize this attribute.
