  • Method Details

    • 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

    • 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
