| MethodExpression | | public MethodExpression()(Code) | | Base constructor
|
| MethodExpression | | public MethodExpression(Method method)(Code) | | Convenience constructor sets method property
Parameters:
method - the Method whose return value when invoked on the bean will the value of this expression |
| evaluate | | public Object evaluate(Context context)(Code) | | Evaluate by calling the read method on the current bean
Parameters:
context - the context against which this expression will be evaluated the value returned by the method when it's invoked on the context's bean,so long as the method can be invoked.Otherwise, null. |
| findAlternateMethod | | protected Method findAlternateMethod(Class type, Method method)(Code) | | Tries to find an alternate method for the given type using interfaces
which gets around the problem of inner classes,
such as on Map.Entry implementations.
Parameters:
type - the Class whose methods are to be searched
Parameters:
method - the Method for which an alternative is to be search for the alternative Method, if one can be found. Otherwise null. |
| getMethod | | public Method getMethod()(Code) | | Gets the method used to evaluate this expression.
the method whose value (when invoked against the context's bean) will be used to evaluate this expression. |
| handleException | | protected void handleException(Context context, Exception e, Method m)(Code) | | Log error to context's logger.
Allows derived objects to handle exceptions differently.
Parameters:
context - the Context being evaluated when the exception occured
Parameters:
e - the exception to handle

| handleException | | protected void handleException(Context context, Exception e)(Code) | | Log error to context's logger.

Parameters:

Parameters:
e - the exception to handle |
| setMethod | | public void setMethod(Method method)(Code) | | Sets the method used to evaluate this expression
Parameters:
method - method whose value (when invoked against the context's bean) will be used to evaluate this expression |
