  - TYPE_MASK_UNIVERSAL_CLASS
```
public static final byte TYPE_MASK_UNIVERSAL_CLASS
```
    A mask that may be used when building a BER type in the universal class. To build the type, perform a bitwise OR with one of the TYPE_MASK_*_CLASS constants, one of the TYPE_MASK_PC_* constants, and a byte that represents the desired tag number. Note that this method only works for tag numbers between zero and thirty, since tag numbers greater than thirty require a multi-byte type, but none of the LDAP specifications attempt to use a tag number greater than twenty-five, so it is highly unlikely that you will ever encounter the need for a multi-byte type in LDAP.
