java.lang.Object org.springframework.scripting.jruby.JRubyScriptFactory
public class JRubyScriptFactory
ScriptFactory
implementation
for a JRuby script.
Typically used in combination with a
ScriptFactoryPostProcessor
;
see the latter's javadoc for a configuration example.

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. |

public JRubyScriptFactory(String scriptSourceLocator, Class[] scriptInterfaces)
scriptSourceLocator
- a locator that points to the source of the script.
Interpreted by the post-processor that actually creates the script.scriptInterfaces
- the Java interfaces that the scripted object
is supposed to implementMethod Detail |

public void setBeanClassLoader(ClassLoader classLoader)
BeanClassLoaderAware
class loader
to
a bean instance.
Invoked after the population of normal bean properties but
before an initialization callback such as
InitializingBean's
InitializingBean.afterPropertiesSet()
method or a custom init-method.
setBeanClassLoader
in interface BeanClassLoaderAware
classLoader
- the owning class loader; may be null
in
which case a default ClassLoader
must be used, for example
the ClassLoader
obtained via
ClassUtils.getDefaultClassLoader()
public String getScriptSourceLocator()
ScriptFactory
Typical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").

public Class[] getScriptInterfaces()
ScriptFactory
Can return null
if the script itself determines
its Java interfaces (such as in the case of Groovy).

public Object getScriptedObject(ScriptSource scriptSource, Class[] actualInterfaces) throws IOException, ScriptCompilationException
getScriptedObject
in interface ScriptFactory
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
)
IOException
- if script retrieval failed
ScriptCompilationException
- if script compilation failedJRubyScriptUtils.createJRubyObject(String, Class[], ClassLoader)
public Class getScriptedObjectType(ScriptSource scriptSource) throws IOException, ScriptCompilationException
ScriptFactory
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.
getScriptedObjectType
in interface ScriptFactory
scriptSource
- the actual ScriptSource to retrieve
the script source text from (never null
)
null
if none could be determined

- if script retrieval failed
ScriptCompilationException
- if script compilation failedpublic String toString()
