Class Initializer

  +--org.omg.CORBA.Initializer
All Implemented Interfaces:
IDLEntity, Serializable

public final class Initializer
extends Object
implements IDLEntity

This is the mapping for an IDL structure which specifies an initializer for a value type. A value can contain all the elements that an interface can as well as the definition of state members, and initializers for that state. In order to ensure portability of value implementations, designers may also define the signatures of initializers (or constructors) for non abstract value types. Syntactically these look like local operations except that they use the keyword init for the "name" of the operation, have no return type, and must use only in parameters. There may be any number of init declarations, as long as the signatures of all the initializers declared within the same scope are unique. Using the same signature as one found in a less-derived type is allowed. The mapping of initializers is language specific and may not always result in a one to one correspondence between initializer signatures and the programming language constructs into which they map. This is because the mapping from IDL types into programming language types is not isomorphic; several different IDL types may map to the same programming language type. Hence defining initializers with the same number of parameters with types that are "similar" (e.g. char and wchar, signed and unsigned integers, etc.) should be done with care. Value types may also be abstract. They are called abstract because an abstract value type may not be instantiated. No or may be specified. However, local operations may be specified. Essentially they are a bundle of operation signatures with a purely local implementation. Note that a concrete value type with an empty state is not an abstract value type. The following shows an example of defining a value type with an initializer. Example: valuetype EmployeeRecord { private string name; private string email; private string SSN; init(in string name, in string SSN); }; Value types do not map to org.omg.CORBA.Object's.
