## [Java] Class CompareIdentityExpression

- org.codehaus.groovy.transform.sc.transformers.CompareIdentityExpression

- All Implemented Interfaces and Traits:
    org.objectweb.asm.Opcodes

      public class CompareIdentityExpression
      extends BinaryExpression

  Compares two objects using identity comparison. This expression will generate bytecode using the IF_ACMPNE instruction, instead of using the "equals" method that is currently mapped to "==" in Groovy. This expression should only be used to compare to objects, not primitives, and only in the context of reference equality check.
