| <div class="block">Only the values of like types are permitted to be compared. A type is like another type if they |
| correspond to the same Java language type, or if one is a primitive Java language type and the |
| other is the wrapped Java class type equivalent (e.g., int and Integer are like types in this |
| sense). |
| <p> |
| There is one exception to this rule: it is valid to compare numeric values for which the rules of |
| numeric promotion apply. Conditional expressions attempting to compare non-like type values are |
| disallowed except for this numeric case. |
| <p> |
| Note that the arithmetic operators and comparison operators are permitted to be applied to |
| state-fields and input parameters of the wrapped Java class equivalents to the primitive numeric |
| Java types. Two entities of the same abstract schema type are equal if and only if they have the |
| same primary key value. Only equality/inequality comparisons over enumeration constants are |
| required to be supported. |
