Abstract

As to an object-oriented programming, reuse of softwares is enhanced and running speed is improved. There are made up a data element list in which pointers to data storage areas of object A are arranged and a pointer element list in which pointers to pointer storage areas of object B are arranged. A combination of the data element list and the pointer element list makes it possible to directly refer to data of the object A from the object B.

Claims

1. A component builder apparatus, comprising:

a first handler to selectively indicate making of methods and messages;

a second handler to designate a desired event of existing software; and

a component builder to build a component which serves as one object in combination with the existing software, the component including a method in response to an indication of making of the method by said first handler and designation of a first event of the existing software by said second handler, the method firing in response to a first message issued by another object to issue the first event, and the component including a message in response to an indication of making of a second message by said first handler and designation of a second event of the existing software by said second handler, the second message issuing in response to occurrence of the second event, to inform other objects that the second event occurred.

2. An object-oriented programming supporting apparatus, comprising:

a component file to store components, each component serving as one object in combination with corresponding existing software, and including a method of issuing an event of the corresponding existing software through firing in response to a message issued by another object, and a message for informing other objects that the event has issued through executing the method;

a handler to input an instruction to issue the event of the corresponding existing software;

an event log file to store a list of the events of the existing software, to be sequentially issued in accordance with an operation of said handler; and

a component coupler to take out sequentially the events from said event log file, to combine the message of a first component issuing the message for informing the other objects that the event is issued and the method of a second component for issuing the event.
