Constructor Detail

AnalyzeExceptionAttribute

public AnalyzeExceptionAttribute(CompositeEntity container,
                                 java.lang.String name)
                          throws NameDuplicationException,
                                 IllegalActionException

Create a new actor in the specified container with the specified name. The name must be unique within the container or an exception is thrown. The container argument must not be null, or a NullPointerException will be thrown.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container (see the setContainer() method).

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

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the actor into the specified workspace.

Overrides:

clone in class CatchExceptionAttribute

Parameters:

workspace - The workspace for the new object.

Returns:

A new actor.

Throws:

java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.

handleException

public boolean handleException(NamedObj context,
                               java.lang.Throwable exception)
                        throws IllegalActionException

Handle an exception according to the specified policy: analyze: Determine the source actor(s) and annotate output ports with error constraints. others: Delegate to parent class

Specified by:

handleException in interface ExceptionHandler

Overrides:

handleException in class CatchExceptionAttribute

Parameters:

context - The object in which the error occurred.

exception - The exception to be handled.

Returns:

true if the exception is handled; false if this attribute did not handle it

Throws:

IllegalActionException - If there is a problem writing to the log file
