Constructor Detail

InvalidInstanceStateException

public InvalidInstanceStateException(java.util.UUID instanceID,
                                     ProcessConstants.InstanceExecutionStatus currentExecutionState,
                                     java.lang.String message)

Parameters:

instanceID - The ID of the instance which is in the wrong execution state for the desired action.

currentExecutionState - The current execution state of the instance.

message - A message to display to the user.

Method Detail

getInstanceID

public java.util.UUID getInstanceID()

Gets the execution status of the instance which has led to this exception or null in case a migration state has led to this exception.

Returns:

The migration status of the instance which has led to this exception or null in case it an execution state has led to this exception.

getInstanceExecutionStatus

public ProcessConstants.InstanceExecutionStatus getInstanceExecutionStatus()

Gets the execution status of the instance which has led to this exception or null in case a migration state has led to this exception.

Returns:

The execution status of the instance which has led to this exception or null in case a migration state has led to this exception.

getInstanceMigrationStatus

public ProcessConstants.InstanceMigrationStatus getInstanceMigrationStatus()

Gets the migration status of the instance which has led to this exception or null in case an execution state has led to this exception.

Returns:

The migration status of the instance which has led to this exception or null in case an execution state has led to this exception.

getPreventingState

public java.lang.String getPreventingState()

Gets the string representation of the state which prevents the desired action and which has led to this exception. This is either the name of the current migration state or the current execution state.
