Method Detail

createBshObject

public static java.lang.Object createBshObject(java.lang.String scriptSource)
                                        throws bsh.EvalError
Create a new BeanShell-scripted object from the given script source.

With this createBshObject variant, the script needs to declare a full class or return an actual instance of the scripted object.

Parameters:
scriptSource - the script source text
Returns:
the scripted Java object
Throws:
bsh.EvalError - in case of BeanShell parsing failure

createBshObject

public static java.lang.Object createBshObject(java.lang.String scriptSource,
                                               java.lang.Class[] scriptInterfaces)
                                        throws bsh.EvalError
Create a new BeanShell-scripted object from the given script source, using the default ClassLoader.

The script may either be a simple script that needs a corresponding proxy generated (implementing the specified interfaces), or declare a full class or return an actual instance of the scripted object (in which case the specified interfaces, if any, need to be implemented by that class/instance).

Parameters:
scriptSource - the script source text
scriptInterfaces - the interfaces that the scripted Java object is supposed to implement (may be null or empty if the script itself declares a full class or returns an actual instance of the scripted object)
Returns:
the scripted Java object
Throws:
bsh.EvalError - in case of BeanShell parsing failure

createBshObject

public static java.lang.Object createBshObject(java.lang.String scriptSource,
                                               java.lang.Class[] scriptInterfaces,
                                               java.lang.ClassLoader classLoader)
                                        throws bsh.EvalError
Create a new BeanShell-scripted object from the given script source.

The script may either be a simple script that needs a corresponding proxy generated (implementing the specified interfaces), or declare a full class or return an actual instance of the scripted object (in which case the specified interfaces, if any, need to be implemented by that class/instance).

Parameters:
scriptSource - the script source text
scriptInterfaces - the interfaces that the scripted Java object is supposed to implement (may be null or empty if the script itself declares a full class or returns an actual instance of the scripted object)
classLoader - the ClassLoader to create the script proxy with
Returns:
the scripted Java object
Throws:
bsh.EvalError - in case of BeanShell parsing failure
