                 throws java.lang.ClassNotFoundException

Construct a new instance.

Parameters:

name - The AttributeDefImpl instance name. Must be unique for for the parent StructureDefImpl instance.

type - The type of the value that is returned by this AttributeDefImpl instance.

accName - The name that should be used to acquire the AttributeDefImpl value from the owning StructureDefImpl. If The owning StructureDefImpl instance is dynamic then this should be a map key. If the owning StructureDefImpl instance references a a JavaBean then this should be a JavaBean property name.

editable - a boolean indicating if the AttributeDefImpl value is editable.

index - The index of the AttributeDefImpl instance in its owning StructureDefImpl instance.
