Example 1 with Element

use of org.eclipse.persistence.internal.oxm.schema.model.Element in project eclipselink by eclipse-ee4j.

the class SchemaGenerator method buildSchemaComponentsForXPath.

/**
 * This method will build element/complexType/typedefparticle components for a given xml-path,
 * and return an XmlPathResult instance containg the sequence that the target should be added
 * to, as well as the current schema - which could be different than the working schema used
 * before calling this method in the case of a prefixed path element from a different namespace.
 * Regarding the path 'target', if the xml-path was "contact-info/address/street", "street"
 * would be the target.  In this case the sequence containing the "address" element would be
 * set in the XmlPathResult to be returned.
 *
 * The exception case is an 'any', where we want to process the last path element before
 * returning - this is necessary due to the fact that an Any will be added to the sequence
 * in place of the last path element by the calling method.
