public interface ScriptFactory
Script definition interface, encapsulating the configuration
of a specific script as well as a factory method for
creating the actual scripted Java Object.

|---|---|
Object |
getScriptedObject(ScriptSource scriptSource,
Class[] actualInterfaces)
Factory method for creating the scripted Java object. |
Class |
getScriptedObjectType(ScriptSource scriptSource)
Determine the type of the scripted Java object. |
Class[] |
getScriptInterfaces()
Return the business interfaces that the script is supposed to implement. |
String |
getScriptSourceLocator()
Return a locator that points to the source of the script. |
boolean |
requiresConfigInterface()
Return whether the script requires a config interface to be generated for it. |
boolean |
requiresScriptedObjectRefresh(ScriptSource scriptSource)
Determine whether a refresh is required (e.g. through ScriptSource's isModified() method). |
| Method Detail |
|---|
String getScriptSourceLocator()
Typical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").
ScriptFactoryPostProcessor.convertToScriptSource(java.lang.String, java.lang.String, org.springframework.core.io.ResourceLoader),
ResourceLoaderClass[] getScriptInterfaces()
Can return null if the script itself determines
its Java interfaces (such as in the case of Groovy).
boolean requiresConfigInterface()
