Constructor Detail

ExpressionShellTableau

public ExpressionShellTableau(ExpressionShellEffigy container,
                              java.lang.String name)
                       throws IllegalActionException,
                              NameDuplicationException

Create a new tableau. The tableau is itself an entity contained by the effigy and having the specified name. The frame is not made visible automatically. You must call show() to make it visible.

Parameters:

container - The containing effigy.

name - The name of this tableau within the specified effigy.

Throws:

IllegalActionException - If the tableau is not acceptable to the specified container.

NameDuplicationException - If the container already contains an entity with the specified name.
