de.aristaflow.adept2.model.execution.InvalidActivityStateException

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

InvalidRuntimeManagerException

public class InvalidActivityStateException
extends java.lang.Exception

This exception will be raised if an activity (a process step) is not in the right state to perform a desired state transition. Besides the ProcessConstants.NodeState this can also be the iteration count or a similar node attribute.

Constructor Detail

InvalidActivityStateException

protected InvalidActivityStateException(java.lang.String msg,
                                        ProcessConstants.NodeState activityState,
                                        java.lang.Throwable cause)

Constructs a new InvalidActivityStateException which encapsulates a string, the current state of the activity and the cause for this exception. The cause is usually used by specific subclasses.

Parameters:

msg - The message for the exception.

activityState - The current state of the activity (process step) which prevents the desired state transition.

cause - The exception causing the InvalidActivityStateException providing additional information.

                                        java.lang.Throwable cause)

Constructs a new InvalidActivityStateException which encapsulates a string, the current state of the activity, the agent executing the activity and the cause for this exception. The cause is usually used by specific subclasses.

Parameters:

msg - The message for the exception.

activityState - The current state of the activity (process step) which prevents the desired state transition.

agent - The performing agent who executes or has executed the corresponding activity.

cause - The exception causing the InvalidActivityStateException providing additional information.

InvalidActivityStateException

public InvalidActivityStateException(java.lang.String msg,
                                     ProcessConstants.NodeState activityState,
                                     QualifiedAgent agent)

Constructs a new InvalidActivityStateException which encapsulates a string, the current state of the activity and the agent.

Parameters:

msg - The message for the exception.

activityState - The current state of the activity (process step) which prevents the desired state transition.

agent - The performing agent who executes or has executed the corresponding activity.

InvalidActivityStateException

public InvalidActivityStateException(java.lang.String msg,
                                     ProcessConstants.NodeState activityState)

Constructs a new InvalidActivityStateException which encapsulates a string and the current state of the activity.

Parameters:

msg - The message for the exception.

activityState - The current state of the activity (process step) which prevents the desired state transition.

InvalidActivityStateException

public InvalidActivityStateException(java.lang.String msg)

Constructs a new InvalidActivityStateException which encapsulates a string describing the node attribute that has the wrong state for the desired state transition.

Parameters:

msg - The message for the exception describing the problem (not caused by a NodeState).

Method Detail

getActivityState

public ProcessConstants.NodeState getActivityState()

Returns the state the process step was in and that prevented the desired state transition. This will be null in case the NodeState is not the problem but another node attribute.

Returns:

The state of the process step that caused the exception or null in case this exception is not raised due to a NodeState.

getAgent

public QualifiedAgent getAgent()

Returns the agent who is currently executing or has executed the activity that caused this exception. This will be null in case the activity has no assigned agent.

Returns:

The agent assigned to the activity that caused the exception or null in case the activity has no assigned agent.
