Class BasicAttributePDP

java.lang.Object
  org.eclipse.higgins.util.idas.cp.BasicAttributePDP

All Implemented Interfaces:

org.eclipse.higgins.idas.api.IAttribute, org.eclipse.higgins.idas.api.IHasAttributes

public class BasicAttributePDP

extends Object

implements org.eclipse.higgins.idas.api.IAttribute

Helper routines for Higgins Context providers that implement some type of PDP. This implementation allows for PDPs at critical points for converting types and values, both for the core properties and for the metadata associated with the attribute.

• getValues()

BasicAttributePDP

public BasicAttributePDP(IAttributePDPs attributePDP,
                         IAttributePDPs attributeMetaAttrPDP,
                         IAttributePDPs attributeValueMetaAttrPDP,

                  throws org.eclipse.higgins.idas.api.IdASException

Create a new PDP based attribute which calls out to do conversions.

Parameters:

attributePDP - The PDP for the attribute conversions.

attributeMetaAttrPDP - The PDP for Attribute meta-attribute conversions.

attributeValueMetaAttrPDP - The PDP for Attribute Value meta-attribute conversions.

attribute - The object we will wrap, it is the unmapped value, this could be provider or consumer value

isProviderAttr - indicates if the value passed is provider or consumer. Pass true if the value is provider based.

Throws:

org.eclipse.higgins.idas.api.IdASException
