      org.mmbase.bridge.implementation.BasicFunctionValue

All Implemented Interfaces:

FieldValue

public class BasicFunctionValue
extends AbstractFieldValue

This implementation of the Field Value interface is used by Node.getFunctionValue(java.lang.String, java.util.List) of Node. This represents the result of a `function' on a node and it (therefore) is a unmodifiable.

cloud - the cloud under which the call was run, used to instantiate NodeList values

Method Detail

convert

protected static Object convert(Object o,
                                Cloud cloud)

get

public Object get()

Description copied from interface: FieldValue

Returns the value as an Object. The object type may vary and is dependent on how data was stored in a field. I.e. It may be possible for an Integer field to return it's value as a String if it was stored that way in the first place.

Specified by:

get in interface FieldValue

Specified by:

get in class AbstractFieldValue

Returns:

the field value as an object
