```
public MethodInfo getMethodInfo(ELContext context)
                         throws ELException
```
    Specified by:
    
    getMethodInfo in class MethodExpression
    
    Parameters:
    context - The EL context for this evaluation
    
    Returns:
    Information about the method that this expression resolves to
    
    Throws:
    
    PropertyNotFoundException - If a property/variable resolution failed because no match was found or a match was found but was not readable
    
    MethodNotFoundException - If no matching method can be found
    
    ELException - Wraps any exception throw whilst resolving the property
  - invoke
```
public Object invoke(ELContext context,
            Object[] params)
              throws ELException
```
    Specified by:
    
    invoke in class MethodExpression
    
    Parameters:
    context - The EL context for this evaluation
    params - The parameters with which to invoke this method expression
    
    Returns:
    The result of invoking this method expression
    
    Throws:
    
    PropertyNotFoundException - If a property/variable resolution failed because no match was found or a match was found but was not readable
    
    MethodNotFoundException - If no matching method can be found
    
    ELException - Wraps any exception throw whilst resolving the property or coercion of the result to the expected return type fails
