`void` `initializers(Initializer[] value)` The initializers attribute lists the initializers this value type supports.
`boolean` `is_a(java.lang.String id)` The is_a operation returns TRUE if the value on which it is invoked either is identical to or inherits, directly or indirectly, from the interface or value identified by its id parameter.
`boolean` `is_abstract()` The is_abstract attribute is TRUE if the value is an abstract value type.
`void` `is_abstract(boolean value)` The is_abstract attribute is TRUE if the value is an abstract value type.
`boolean` `is_custom()` The is_custom attribute is TRUE if the value uses custom marshaling.
`void` `is_custom(boolean value)` The is_custom attribute is TRUE if the value uses custom marshaling.
`boolean` `is_truncatable()` The is_truncatable attribute is TRUE if the value inherits "safely" (i.e., supports truncation) from another value.
`void` `is_truncatable(boolean value)` The is_truncatable attribute is TRUE if the value inherits "safely" (i.e., supports truncation) from another value.
`InterfaceDef[]` `supported_interfaces()` The supported_interfaces attribute lists the interfaces which this value type supports.
`void` `supported_interfaces(InterfaceDef[] value)` The supported_interfaces attribute lists the interfaces which this value type supports.

  The is_abstract attribute is TRUE if the value is an abstract value type.

### is_custom

    public boolean is_custom()

  The is_custom attribute is TRUE if the value uses custom marshaling.

### is_custom

    public void is_custom(boolean value)

  The is_custom attribute is TRUE if the value uses custom marshaling.
