Field Detail

statusMessage

public StringParameter statusMessage

A status message reflecting the success or failure of actions taken upon occurrence of an exception. Implemented as a public parameter so the message can be displayed in the icon.

Constructor Detail

ExceptionAnalyzer

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

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.

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.

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 Attribute

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.

exceptionOccurred

public boolean exceptionOccurred(java.lang.String policy,
                                 java.lang.Throwable exception)

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:

exceptionOccurred in interface ExceptionSubscriber

Parameters:

policy - The policy

exception - The exception that occurred

Returns:

true if the solver completed successfully.

exceptionHandled

public boolean exceptionHandled(boolean succesful,
                                java.lang.String message)

Nothing to do after exception is handled. return true always, since there is nothing to do after handling

Specified by:

exceptionHandled in interface ExceptionSubscriber

Parameters:

succesful - True if the exception was successfully handled; false otherwise

message - A status message from the exception handler

Returns:

True if the subscriber successfully processed the information; false otherwise (for example, an ExceptionEmailer that fails to send an email)
