An attribute to identify an object in the pattern to be created. When an object
in the pattern contains one such attribute, it is essentially not part of the
pattern because it is ignored in pattern matching. When a match is found, the
object would be created in the result.
Construct an attribute with the given name contained by the specified
entity. 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.
Increment the version of the workspace.
container - The container.
name - The name of this attribute.
IllegalActionException - If the attribute is not of an
acceptable class for the container, or if the name contains a period.
Construct an attribute in the specified workspace with 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.
The object is added to the directory of the workspace.
Increment the version number of the workspace.
workspace - The workspace that will list the attribute.
