INTERNAL: TransformationAccessor. Transformation annotation may or may not be present on the accessible object. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - any metadata mapped from XML to this class must be handled in the merge method. (merging is done at the accessor/mapping level) - any metadata mapped from XML to this class must be initialized in the initXMLObject method. - methods should be preserved in alphabetical order.

public List<WriteTransformerMetadata> getWriteTransformers()

INTERNAL: Used for OX mapping.

hashCodeback to summary
public int hashCode()

Overrides org.eclipse.persistence.internal.jpa.metadata.accessors.mappings.BasicAccessor.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object.
