INTERNAL: Object to hold onto an attribute override meta data. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - when loading from annotations, the constructor accepts the metadata accessor this metadata was loaded from. Used it to look up any 'companion' annotation needed for processing. - methods should be preserved in alphabetical order.

hashCodeback to summary
public int hashCode()

Overrides org.eclipse.persistence.internal.jpa.metadata.columns.OverrideMetadata.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.
