Examples with XMLNullRepresentationType org.eclipse.persistence.oxm.mappings.nullpolicy.XMLNullRepresentationType used on opensource projects

Example 1 with XMLNullRepresentationType

use of org.eclipse.persistence.oxm.mappings.nullpolicy.XMLNullRepresentationType in project eclipselink by eclipse-ee4j.

the class XmlBindingsGenerator method isDefaultNullPolicy.

/**
 * Indicates is a given AbstractNullPolicy is the default.  This is useful
 * if it is not desirable to write out the default policy in the oxm
 * metadata file.
 *
 * The default policy is NullPolicy, with the following set:
 * <ul>
 * <li>isNullRepresentedByXsiNil = false
 * <li>isNullRepresentedByEmptyNode = true
 * <li>isSetPerformedForAbsentNode = true
 * <li>marshalNullRepresentation = XMLNullRepresentationType.ABSENT_NODE
 * </ul>
