| Method Summary | |
| public Object | apply(String source, int lineNo, int columnNo, Object funcBody, Vector paramNames, Vector arguments)
Default impl of apply - calls eval ignoring parameters and returns
the result. | | public void | compileApply(String source, int lineNo, int columnNo, Object funcBody, Vector paramNames, Vector arguments, CodeBuffer cb)
Default impl of compileApply - calls compileExpr ignoring parameters. | | public void | compileExpr(String source, int lineNo, int columnNo, Object expr, CodeBuffer cb)
Default impl of compileExpr - generates code that'll create a new
manager, evaluate the expression, and return the value. | | public void | compileScript(String source, int lineNo, int columnNo, Object script, CodeBuffer cb)
Default impl of compileScript - generates code that'll create a new
manager, and execute the script. | | public void | declareBean(BSFDeclaredBean bean)
| | public void | exec(String source, int lineNo, int columnNo, Object script)
Default impl of execute - calls eval and ignores the result. | | public void | iexec(String source, int lineNo, int columnNo, Object script)
Default impl of interactive execution - calls eval and ignores the result. | | public void | initialize(BSFManager mgr, String lang, Vector declaredBeans)
initialize the engine; called right after construction by
the manager. | | public void | propertyChange(PropertyChangeEvent e)
Receive property change events from the manager and update my fields
as needed. | | public void | terminate()
| | public void | undeclareBean(BSFDeclaredBean bean)
|
| compileExpr | | public void compileExpr(String source, int lineNo, int columnNo, Object expr, CodeBuffer cb) throws BSFException(Code) | | Default impl of compileExpr - generates code that'll create a new
manager, evaluate the expression, and return the value.
|
| compileScript | | public void compileScript(String source, int lineNo, int columnNo, Object script, CodeBuffer cb) throws BSFException(Code) | | Default impl of compileScript - generates code that'll create a new
manager, and execute the script.
|
| exec | | public void exec(String source, int lineNo, int columnNo, Object script) throws BSFException(Code) | | Default impl of execute - calls eval and ignores the result.
|
| iexec | | public void iexec(String source, int lineNo, int columnNo, Object script) throws BSFException(Code) | | Default impl of interactive execution - calls eval and ignores the result.
|
| initialize | | public void initialize(BSFManager mgr, String lang, Vector declaredBeans) throws BSFException(Code) | | initialize the engine; called right after construction by
the manager. Declared beans are simply kept in a vector and
that's it. Subclasses must do whatever they want with it.
|
| propertyChange | | public void propertyChange(PropertyChangeEvent e)(Code) | | Receive property change events from the manager and update my fields
as needed.
Parameters:
e - PropertyChange event with the change data |
| terminate | | public void terminate()(Code) | | |
