Method Details

close

void close() throws IOException

Disconnect from the server.

Throws:

IOException - engine crash or problem in communication.

getVersion

String getVersion() throws IOException, EngineException

Returns the version string of the server. The stub must be connected.

Returns:

The version

Throws:

IOException - engine crash or problem in communication.

EngineException - problem in the Uppaal engine.

getOptionsInfo

String getOptionsInfo() throws EngineException, IOException

Returns information about available options. The information is returned as an XML document. The stub must be connected.

Returns:

The options information

Throws:

IOException - engine crash or problem in communication.

EngineException - problem in the Uppaal engine.

setOptions

void setOptions(String options) throws EngineException, IOException

Sets server options used for verification. The stub must be connected. TODO: Document format.

Parameters:

options - - The options string

Throws:

IOException - engine crash or problem in communication.

EngineException - problem in the Uppaal engine.

getSymbolicInitial

SymbolicState getSymbolicInitial(UppaalSystem system) throws EngineException, IOException, CannotEvaluateException

Returns the symbolic initial state for the system. The stub must be connected and the system must be the last one uploaded to the server.

Parameters:

system - the compiled Uppaal system representation.

Returns:

initial symbolic state.

Throws:

IOException - I/O communication error.

EngineException - error in the server protocol.

CannotEvaluateException - some expression could not be evaluated.

getConcreteInitial

ConcreteState getConcreteInitial(UppaalSystem system) throws EngineException, IOException, CannotEvaluateException

Returns the concrete initial state for the system. The stub must be connected and the system must be the last one uploaded to the server.

Parameters:

system - the compiled Uppaal system representation.

Returns:

initial concrete state

Throws:

IOException - I/O communication error.

EngineException - error in the server protocol.

CannotEvaluateException - some expression could not be evaluated.

getConcreteSuccessor

ConcreteSuccessor getConcreteSuccessor(UppaalSystem system, ConcreteState state, SystemEdgeSelect[] edges, BigDecimal currentTime, BigDecimal delay) throws EngineException, IOException, CannotEvaluateException

Get the concrete simulation successor

Parameters:

system - - The uppaal system

state - - The concrete simulator state

edges - - The vector of the selected system edges

currentTime - - the current simulation time

delay - - The delay time

Returns:

concrete successor object

Throws:

IOException - I/O communication error.

EngineException - error in the server protocol.

CannotEvaluateException - some expression could not be evaluated.

getGanttChart

EngineException - error in the server protocol.

getTransitions

ArrayList<SymbolicTransition> getTransitions(UppaalSystem system, SymbolicState state) throws EngineException, IOException, CannotEvaluateException

Returns the list of outgoing transitions for the state. The stub must be connected, the state must belong to the system, and the system must be the last one uploaded to the server.

Parameters:

system - - The uppaal system

state - - The symbolic state of the system

Returns:

The array list of the symbolic transition

upload

UppaalSystem upload(Document document, ArrayList<Problem> problems) throws EngineException, IOException

Upload the document to the server. If no errors occurred, the instantiated system is returned. Otherwise, null is returned and error reports are stored in the problems vector. Even if no errors occurred, warnings may have been added to the problems vector. The stub must be connected.

Parameters:

document - - The system document

problems - - The problem array list

Returns:

the compiled system representation
