Method Detail

createBshObject

public static Object createBshObject(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 Object createBshObject(String scriptSource,
                                     @Nullable
                                     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 Object createBshObject(String scriptSource,
                                     @Nullable
                                     Class<?>[] scriptInterfaces,
                                     @Nullable
                                     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 use for evaluating the script

Returns:

the scripted Java object

Throws:

bsh.EvalError - in case of BeanShell parsing failure
