    • isEquivalentTo

      public boolean isEquivalentTo(Expression other)
      Description copied from interface: Expression
      Returns whether this expression will accept the same values as another.

      If this returns true, the expressions are guaranteed to return the same evaluation for the same input. However, if this returns false the expressions may return the same evaluation for the same input. That is, expressions may be equivalent even if this returns false.

      For best results, rewrite not and bind expressions before calling this method.

      Specified by:
      isEquivalentTo in interface Expression
      Parameters:
      other - another expression
      Returns:
      true if the expressions are equivalent
