Modifier and Type	Method and Description
java.lang.Object	apply(java.lang.String source, int lineNo, int columnNo, java.lang.Object funcBody, java.util.Vector paramNames, java.util.Vector arguments) Evaluate an anonymous function (differs from eval() in that apply() handles multiple lines).

void	declareBean(org.apache.bsf.BSFDeclaredBean bean) Declare a bean
java.lang.Object	eval(java.lang.String source, int lineNo, int columnNo, java.lang.Object script) Evaluate an expression.
void	exec(java.lang.String source, int lineNo, int columnNo, java.lang.Object script) Execute a script.
void	iexec(java.lang.String source, int lineNo, int columnNo, java.lang.Object script) Execute script code, emulating console interaction.
void	initialize(org.apache.bsf.BSFManager mgr, java.lang.String lang, java.util.Vector declaredBeans) Initialize the engine.
void	undeclareBean(org.apache.bsf.BSFDeclaredBean bean) Undeclare a previously declared bean.
