Abstract

A build object of build class Builder has build method build (Object resolved) for building reference relations among construction-element objects by calling a field setting method owned by construction-element object resolved. A get object of class Getter has get method get object ( ) for acquiring a construction-element object and is also allowed to own a build object. In the get object, construction-element object resolved is acquired by calling get method get object ( ). In a build object owned by the get object, construction-element object resolved acquired by the get object is initialized by build method build (Object resolved). By adopting the procedure described above, construction-element objects required for constructing desired software such as an application program can be collected for constructing the desired software.

Claims

1. An information processing apparatus for carrying out processing to construct desired software by acquiring a plurality of construction-element objects required for constructing said desired software and initializing said construction-element objects, said information processing apparatus comprising:

build objects each owning a build method which is used for constructing reference relations among said construction-element objects by calling a field setting method if said construction-element objects each have said field setting method for setting a field of said construction-element object in order to initialize said construction-element object; and

get objects which each own a get method for acquiring a construction-element object and are each capable of owning one of said build objects,

wherein said get objects are each used for acquiring a construction-element object by using said get method of said get object;

said build object owned by said get object is used for initializing a construction-element object acquired by said get object by using said build method owned by said build object; and

each of said construction-element objects is capable of owning one of said field setting method or a plurality of said field setting methods.

2. An information processing apparatus according to claim 1,

wherein said build objects are each capable of owning one of said get objects; and

said get object owned by said build object used for initializing a construction-element object is used for acquiring another construction-element object required for initializing said construction-element object.

3. An information processing apparatus according to claim 2 further comprising a bind object owning a method for cataloging a construction-element object acquired by any of said get objects wherein, if said other construction-element object required for initializing said construction-element object has been cataloged by said bind method, said get object acquires said cataloged construction-element object.

4. An information processing apparatus according to claim 1,

wherein each of said construction-element objects is capable of owning a build object for building a new reference relation with said construction-element object.

5. An information processing apparatus according to claim 1,

wherein said get method or said build method is a polymorphic method.

6. An information processing apparatus according to claim 1,

wherein said get object is capable of owning one said build object or a plurality of said build objects;

and

said build objects of said get object are each used for initializing one of fields of a construction-element object acquired by said get object by using said build method of said build object.

7. An information processing apparatus according to claim 1,

wherein said construction-element objects are distributed among geographically scattered sites or distributed along a time axis.

8. An information processing method adopted in an information processing apparatus for carrying out processing to construct desired software by acquiring a plurality of construction-element objects required for constructing said desired software and initializing said construction-element objects, said information processing apparatus comprising:

build objects each owning a build method which is used for constructing reference relations among said construction-element objects by calling a field setting method if said construction-element objects each have said field setting method for setting a field of said construction-element object in order to initialize said construction-element object; and

get objects which each own a get method for acquiring a construction-element object and are each capable of owning one of said build objects,

wherein said get objects are each used for acquiring a construction-element object by using said get method of said get object;

said build object owned by said get object is used for initializing a construction-element object acquired by said get object by using said build method owned by said build object and

wherein each of said construction-element objects is capable of owning one of said field setting method or a plurality of said field setting methods.

9. A recording medium for recording a computer program to be executed by a computer to carry out processing of constructing desired software by acquiring a plurality of construction-element objects required for constructing said desired software and initializing said construction-element objects,

wherein said computer program comprises:

build objects each owning a build method which is used for constructing reference relations among said construction-element objects by calling a field setting method if said construction-element objects each have said field setting method for setting a field of said construction-element object in order to initialize said construction-element object,

each of said construction-element objects being capable of owning one of said field setting method or a plurality of said field setting methods; and

get objects which each own a get method for acquiring a construction-element object and are each capable of owning one of said build objects,

said processing comprising the steps of

letting each of said get objects acquire a construction-element object by using said get method of said get object; and

letting said build object owned by said get object initialize a construction-element object acquired by said get object by using said build method owned by said build object.
