Abstract

A method and apparatus for implementing object-transparent invocation operates in conjunction with a data processing system having a memory, a sender and at least one method capable of performing a function to advantageously deliver a message to the at least one method capable of performing a function, thereby (i) delivering the message without requiring the sender to have specific knowledge of the identity, address, name or existence of the at least one method capable of servicing the message, (ii) delivering the message to the at least one method capable of servicing the message, and/or (iii) delivering the message to the at least one method capable of servicing the message, without the use of identity, address or name information provided by the sender.

Claims

1. In a data processing system having a memory, a sender and at least one method capable of performing a function, a process of delivering a message to the at least one method capable of performing a function, comprising the steps of:

storing, in the memory, an application specific registry having a method identifier corresponding to at least one method capable of performing a function;

receiving a message from the sender;

selecting a method identifier in the registry based upon information contained in the registry; and

,

repeating the steps of selecting and sending until a termination condition is reached, thereby delivering the message to the at least one method capable of servicing the message, without requiring the sender to have specific knowledge of the identity, address, name or existence of the at least one method capable of servicing the message.

2. The process claimed in claim 1, wherein the termination condition of the repeating step is reached when each method identifier in the registry has been selected and the message is sent to the method corresponding to each selected method.

3. The process claimed in claim 1, wherein the termination condition of the repeating step is reached when the method corresponding to the selected method identifier performs a function.

4. The process claimed in claim 1, wherein the termination condition of the repeating step is reached when the method corresponding to the selected method identifier performs a prespecified function.

5. The process claimed in claim 1, wherein the termination condition of the repeating step is reached when the method corresponding to the selected method identifier provides a prespecified indication.

6. The process claimed in claim 1, wherein the message does not contain an identifier uniquely corresponding to any one of the at least one methods.

7. The process claimed in claim 1, wherein the registry further comprises a plurality of rankings, and each of the rankings corresponds to one or more method identifiers, and wherein the process of selecting, selects a method identifier based upon the plurality of rankings.

8. The process claimed in claim 1, further comprising the steps of:

receiving a return value from the method corresponding to the method identifier; and

adding the return value to the message; and

wherein the step of repeating further includes repeating the steps of receiving the return value and adding the return value.

9. In a data processing system having a memory, a sender and at least one method capable of performing a function, a process of delivering a message to the at least one method capable of performing a function, comprising the steps of:

storing, in the memory, an application specific registry having a method identifier corresponding to at least one method capable of performing a function;

receiving a message from the sender;

selecting a method identifier in the registry based solely upon information contained in the registry; and

,

repeating the steps of selecting and sending until a termination condition is reached, thereby delivering the message to the at least one method capable of servicing the message.

10. In a data processing system having a memory, a sender and at least one method capable of performing a function, a process of delivering a message to the at least one method capable of performing a function, comprising the steps of:

storing, in the memory, an application specific registry having a method identifier corresponding to at least one method capable of performing a function;

receiving a message from the sender;

selecting a method identifier in the registry based upon information contained in the registry; and

,

repeating the steps of selecting and sending until a termination condition is reached, thereby delivering the message to the at least one method capable of servicing the message, without the use of identity, address or name information provided by the sender.
