```
public final class StateTransition
extends java.lang.Object
```

- Method Detail
  - getPattern
```
public java.lang.String getPattern()
```
    Returns:
    the pattern the ExitStatus.getExitCode() will be compared against.
  - createEndStateTransition
```
public static StateTransition createEndStateTransition(State state)
```
    Create a new end state StateTransition specification. This transition explicitly goes unconditionally to an end state (i.e. no more executions).
    Parameters:
    state - the State used to generate the outcome for this transition
    Returns:
    StateTransition that was created.
  - createEndStateTransition
```
public static StateTransition createEndStateTransition(State state,
                                                       java.lang.String pattern)
```
    Create a new end state StateTransition specification. This transition explicitly goes to an end state (i.e. no more processing) if the outcome matches the pattern.
    Parameters:
    state - the State used to generate the outcome for this transition
    pattern - the pattern to match in the exit status of the State
    Returns:
    StateTransition that was created.
  - switchOriginAndDestination
```
public static StateTransition switchOriginAndDestination(StateTransition stateTransition,
                                                         State state,
                                                         java.lang.String next)
```
    Convenience method to switch the origin and destination of a transition, creating a new instance.
    Parameters:
    stateTransition - an existing state transition
    state - the new state for the origin
    next - the new name for the destination
    Returns:
    StateTransition that was created.
  - createStateTransition
```
public static StateTransition createStateTransition(State state,
                                                    java.lang.String next)
```
    Create a new state StateTransition specification with a wildcard pattern that matches all outcomes.
    Parameters:
    state - the State used to generate the outcome for this transition
    next - the name of the next State to execute
    Returns:
    StateTransition that was created.
  - createStateTransition
```
public static StateTransition createStateTransition(State state,
                                                    @Nullable
                                                    java.lang.String pattern,
                                                    @Nullable
                                                    java.lang.String next)
```
    Create a new StateTransition specification from one State to another (by name).
    Parameters:
    state - the State used to generate the outcome for this transition
    pattern - the pattern to match in the exit status of the State (can be null)
    next - the name of the next State to execute (can be null)
    Returns:
    StateTransition that was created.
  - getState
```
public State getState()
```
    Public getter for the State.
    Returns:
    the State
  - getNext
```
public java.lang.String getNext()
```
    Public getter for the next State name.
    Returns:
    the next
  - matches
```
public boolean matches(java.lang.String status)
```
    Check if the provided status matches the pattern, signalling that the next State should be executed.
    Parameters:
    status - the status to compare
    Returns:
    true if the pattern matches this status
  - isEnd
```
public boolean isEnd()
```
    Check for a special next State signalling the end of a job.
    Returns:
    true if this transition goes nowhere (there is no next)
  - toString
```
public java.lang.String toString()
```
    Overrides:
    toString in class java.lang.Object
