Method Details

generateClass

public Class generateClass(String name,
 Modifiers modifiers,
 Class[] interfaces,
 Class superClass,
 bsh.BSHBlock block,
 boolean isInterface,
 CallStack callstack,
 Interpreter interpreter)
                    throws EvalError

Description copied from class: ClassGenerator

Parse the BSHBlock for the class definition and generate the class.

Specified by:

generateClass in class ClassGenerator

Throws:

EvalError

invokeSuperclassMethod

public Object invokeSuperclassMethod(BshClassManager bcm,
 Object instance,
 String methodName,
 Object[] args)
                              throws UtilEvalError,
bsh.ReflectError,
InvocationTargetException

Description copied from class: ClassGenerator

Invoke a super.method() style superclass method on an object instance. This is not a normal function of the Java reflection API and is provided by generated class accessor methods.

Specified by:

invokeSuperclassMethod in class ClassGenerator

Throws:

UtilEvalError

bsh.ReflectError

InvocationTargetException

setInstanceNameSpaceParent

public void setInstanceNameSpaceParent(Object instance,
 String className,
 NameSpace parent)

Change the parent of the class instance namespace. This is currently used for inner class support. Note: This method will likely be removed in the future.

Specified by:

setInstanceNameSpaceParent in class ClassGenerator

generateClassImpl

public static Class generateClassImpl(String name,
 Modifiers modifiers,
 Class[] interfaces,
 Class superClass,
 bsh.BSHBlock block,
 boolean isInterface,
 CallStack callstack,
 Interpreter interpreter)
                               throws EvalError

If necessary, parse the BSHBlock for for the class definition and generate the class using ClassGeneratorUtil. This method also initializes the static block namespace and sets it in the class.

Throws:

EvalError

invokeSuperclassMethodImpl

public static Object invokeSuperclassMethodImpl(BshClassManager bcm,
 Object instance,
 String methodName,
 Object[] args)
                                         throws UtilEvalError,
bsh.ReflectError,
InvocationTargetException

Throws:

UtilEvalError
