Class MethodEquals

java.lang.Object

io.ebean.enhance.entity.MethodEquals

All Implemented Interfaces:

Opcodes, EnhanceConstants

public class MethodEquals
extends Object
implements Opcodes, EnhanceConstants

Generate the equals hashCode method using the identity.

This will add a _ebean_getIdentity() equals() and hashCode() methods based on having a single ID property and no existing equals() or hashCode() methods.

Method Detail

addMethods

public static void addMethods(ClassVisitor cv,
                              ClassMeta meta,
                              int idFieldIndex,
                              FieldMeta idFieldMeta)

Adds equals(), hashCode() and _ebean_getIdentity() methods.

If the class already has a equals() or hashCode() method defined then these methods are not added (its a noop).

Parameters:

idFieldIndex - the index of the id field

addIdentityField

public static void addIdentityField(ClassVisitor cv)

The identity field used for implementing equals via the _ebean_getIdentity() method.
