- Method Detail
  - getScriptSourceLocator
```
String getScriptSourceLocator()
```
    Return a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.
    Typical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").
    Returns:
    the script source locator

  - getScriptInterfaces
```
@Nullable
Class<?>[] getScriptInterfaces()
```
    Return the business interfaces that the script is supposed to implement.
    Can return null if the script itself determines its Java interfaces (such as in the case of Groovy).
    Returns:
    the interfaces for the script
  - requiresConfigInterface
```
boolean requiresConfigInterface()
```
    Return whether the script requires a config interface to be generated for it. This is typically the case for scripts that do not determine Java signatures themselves, with no appropriate config interface specified in getScriptInterfaces().
    Returns:
    whether the script requires a generated config interface

    getScriptInterfaces()
  - getScriptedObject

@Nullable
Object getScriptedObject(ScriptSource scriptSource,
                         @Nullable
                         Class<?>... actualInterfaces)
                  throws IOException,
                         ScriptCompilationException
```
    Factory method for creating the scripted Java object.
    Implementations are encouraged to cache script metadata such as a generated script class. Note that this method may be invoked concurrently and must be implemented in a thread-safe fashion.
    Parameters:
    scriptSource - the actual ScriptSource to retrieve the script source text from (never null)
    actualInterfaces - the actual interfaces to expose, including script interfaces as well as a generated config interface (if applicable; may be null)
    Returns:
    the scripted Java object
    Throws:
    IOException - if script retrieval failed
    ScriptCompilationException - if script compilation failed
  - getScriptedObjectType
```
@Nullable
Class<?> getScriptedObjectType(ScriptSource scriptSource)
                        throws IOException,
                               ScriptCompilationException
```
    Determine the type of the scripted Java object.
    Implementations are encouraged to cache script metadata such as a generated script class. Note that this method may be invoked concurrently and must be implemented in a thread-safe fashion.
    Parameters:
    scriptSource - the actual ScriptSource to retrieve the script source text from (never null)
    Returns:
    the type of the scripted Java object, or null if none could be determined
    Throws:
    IOException - if script retrieval failed
    ScriptCompilationException - if script compilation failed
    Since:
    2.0.3
  - requiresScriptedObjectRefresh
```
boolean requiresScriptedObjectRefresh(ScriptSource scriptSource)
```
    Determine whether a refresh is required (e.g. through ScriptSource's isModified() method).
    Parameters:
    scriptSource - the actual ScriptSource to retrieve the script source text from (never null)
    Returns:
    whether a fresh getScriptedObject(org.springframework.scripting.ScriptSource, java.lang.Class<?>...) call is required
