Abstract

A method is described which provides a common architected solution for "flowing" revisable object data around areas that have claimed space from the area into which the flowed data is to reside. The Data Flow Sequence (DFS) Data Structure is shown on the next page. The DFS Data Structure specifies the object Data Flow sequence within the object Area whenever overlapping object Areas have Claimed space from the object Area described by the Structured Field. The selection of various Data Flow Sequence values determines how object data flows within an object Area. There may be 1, 2, 3, 4, or 5 Data Flow Sequence Values. These values may be specified in any order since vertical object data flow occurs in a top to bottom direction while horizontal data flows either left to right or right to left.

Method for Controlling the Flow of Data Around Claimed Space

A method is described which provides a common architected solution for "flowing" revisable object data around areas that have claimed space from the area into which the flowed data is to reside.

The Data Flow Sequence (DFS) Data Structure is shown on the next page. The DFS Data Structure specifies the object Data Flow sequence within the object Area whenever overlapping object Areas have Claimed space from the object Area described by the Structured Field. The selection of various Data Flow Sequence values determines how object data flows within an object Area. There may be 1, 2, 3, 4, or 5 Data Flow Sequence Values. These values may be specified in any order since vertical object data flow occurs in a top to bottom direction while horizontal data flows either left to right or right to left. These Data Flow Sequence values are acted upon whenever the condition within a Claimed Object Area is encountered that matches a Data Flow Sequence Definition. This single triplet specification is valid for all + occurrences of determining data flow within a Claimed Area that may have one or more overlapping Claiming Areas. The valid data flow sequence COD value combinations are listed below. 1 TOP, and/or BOT Not Order sensitive 2 TOP, SKIPV, and/or BOT Not Order sensitive 3 TOP, and/or BOT, LEFTRIGHT Not Order sensitive 4 TOP, SKIPV, SKIPH, and/or BOT, LEFTRIGHT Not Order Sensitive 5 TOP, SKIPV, and/or BOT, LEFTRIGHT Not Order Sensitive 6 TOP, SKIPH, and/or BOT, LEFTRIGHT Not Order Sensitive 7 TOP, and/or BOT, RIGHTLEFT Not Order Sensitive 8 TOP, SKIPV, SKIPH, and/or BOT, RIGHTLEFT Not Order Sensitive 9 TOP, SKIPV, and/or BOT, RIGHTLEFT Not Order Sensitive 10 TOP, SKIPH, and/or BOT, RIGHTLEFT Not Order Sensitive 11 TOP, and/or BOT, LEFTFILL, RIGHTFILL Order Sensitive 12 TOP, SKIPV, and/or BOT, LEFTFILL, RIGHTFILL Order Sensitive 13 TOP, and/or BOT, LEFTFILL Not Order Sensitive 14 TOP, SKIPV, and/or BOT, LEFTFILL Not Order Sensitive 15 TOP, and/or BOT, RIGHTFILL Not Order Sensitive 16 TOP, SKIPV, and/or BOT, RIGHTFILL Not Order Sensitive 17 LEFTRIGHT Not Order Sensitive 18 LEFTRIGHT, SKIPH Not Order Sensitive 19 RIGHTLEFT Not Order Sensitive 20 RIGHTLEFT, SKIPH Not Order Sensitive 21 LEFTFILL Not Order Sensitive 22 RIGHTFILL Not Order Sensitive 23 LEFTFILL, RIGHTFILL Order Sensitive. Note that the only "order" sensitive parameter specification is when LEFTFILL and RIGHTFILL are both specified. Thus, if LEFTFILL is specified before RIGHTFILL, the data flow process places data in all LEFTFILL Area(s) first before proceeding to the RIGHTFILL Area(s). The definition of the data flow sequence parameters is as follows.

The Unclaimed Area between the top X extent of the Claimed Area and the top X extent of the 1st Claiming Area encountered in a top to bottom vertical scan. The Unclaimed Area between the bottom X extent
