Interface FieldFactory

All Known Implementing Classes:

DefaultFieldFactory

public interface FieldFactory

Factory abstract interface for generating field objects from a given node.

The idea of this factory is to break a circular compile dependency between SF/MFNode and all the field classes.

                                                   BaseNodeFactory baseNodeFac)

Create a field given a name from the node.

Parameters:

node - The node to create the field from

field - The name of the field to fetch

checkEventIn - true if we should check for an event in

internal - true if this represents an internal field definition

fieldQueue - The access listener for propogating s2 requests

baseNodeFac - The factory used to create node wrappers

Returns:

An instance of the field class representing the field

Throws:

InvalidEventInException - The field is not an eventIn

InvalidExposedFieldException - The field is not an exposedField
