public MethodReference(Object base,
 Method method,
 Object[] actualParameters,
 boolean fromMethod)

Construct a method reference.

Parameters:

base - The base of the EL method expression.

method - The concrete Method instance of the EL method expression.

Method Details

getBase

public Object getBase()

Returns the base of the EL method expression. Usually, this is the backing bean on which the method behind getMethod() should be invoked.

Returns:

The base of the EL method expression.

getMethod

public Method getMethod()

Returns the concrete Method instance of the EL method expression. Usually, this is a method of the class behind getBase().

Returns:

The concrete Method instance of the EL method expression.

getActualParameters

public Object[] getActualParameters()

Returns the actual (evaluated) parameters of the method call. If there are no params, then this returns an empty array, never null. Those should be passed to Method.invoke(Object, Object...).

Returns:

The actual (evaluated) parameters of the method call.

isFromMethod

public boolean isFromMethod()

Returns true if this method reference is from an actual method call and not from a getter of a property.

Returns:

true if this method reference is from an actual method call and not from a getter of a property.
