Abstract

A system and process for ensuring the smooth flow of electronic ink is described. Dynamic rendering is give priority over other event handlers. Priority may be the use of one or more queues to order when events occur and may be performing dynamic rendering prior to other steps.

Claims

1. A system for processing information comprising:

a storage; and

a processor exchanging information with said a storage, said processor hosting a first component and a second component,

said first component including;

an input that receives information;

a synchronous interface to which a first plug-in object is attached, said first plug-in object processing information received by said first component via said input synchronously with the receipt of said information by said first component;

an output queue receiving information from said first plug-in object; and

an asynchronous interface to which an input of said second component is attached, said second component accessing information in said output queue; and

said second component including a synchronous interface to which a second plug-in object is attached and an asynchronous interface to which a third plug-in object is attached such that said first plug-in object is a dynamic renderer object and such that said third plug-in object is an ink collection object.

2. The system according to claim 1, wherein at least one of said first plug-in object and said second plug-in object form part of a list attached to said component.

3. The system according to claim 1, wherein at least one of said first plug-in object and said second plug-in object form part of a chain attached to said component.

4. The system according to claim 1, wherein said synchronous interface of second component allows said second plug-in object to access information in said output queue.

5. The system according to claim 1, said second component further comprising:

an input queue that temporarily stores information received over said asynchronous interface from said first component, said input queue being accessed by said synchronous interface of said second component.
