How to find all uses of an EDataType/eClassifier [message #901728]

I've search around and haven't found any comments on this, so appologies if I am missing something and have asked a repeat question.

I have the case where I have an ecore with the following:

    <eClassifiers xsi:type="ecore:EDataType" name="AddressType" instanceClassName="java.lang.String">
      <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
        <details key="name" value="address_._type"/>
        <details key="baseType" value="http://www.eclipse.org/emf/2003/XMLType#string"/>
        <details key="maxLength" value="50"/>
      </eAnnotations>
    </eClassifiers>

This is used within the ePackage some-where.

What is the best/easiest way given:

1. An eClassifier/EDataType
2. An ePackage

To find all occurances/uses of the given eClassifier in the ePackage.

i.e.

      <eStructuralFeatures xsi:type="ecore:EAttribute" name="address" eType="/0/AddressType">
        <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
          <details key="kind" value="element"/>
          <details key="name" value="address"/>
        </eAnnotations>
      </eStructuralFeatures>

Any help or suggested code snippets would be greatly appreciated!

Thanks,
Rob

Rob,

EcoreUtil.UsageCrossReferencer.find(eClassifier, ePackage) should do the
trick.
