Method Detail

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.

getMethodInfo

public MethodInfo getMethodInfo()

Returns the standard EL MethodInfo of the MethodExpression where this MethodReference has been extracted from.

Returns:

The standard EL MethodInfo.
