Reason/Goals

Performance of Load/Save will be improved if we got an efficient handling of automatic styles.

The Plan

We will create a property pool which contains all used combinations of hard attributes.

The Steps

Character properties
 Load: Construction of property sets during loading of documents
 Edit: Construction/destruction of property sets during editing the document (manually or by API).
 Format: Use of the property sets for formatting.
 Status: Use of property sets for status reporting(?). 
 Save: Save automatic styles during XML-export.
Ruby properties
 Use of a property pool for ruby attributes
Paragraph properties
 Use of a property pool for paragraph attributes
Other properties
 Use of property pool for other attributes (e.g. tables, graphic objects...)

ToDo

Possible Optimizations

The following list shows some possible future tasks. But they will only implemented if our measurement shows that it is worth to do so.

  • Faster access by name of styles from style pool (cache, hashmap)
  • Remove unused styles from style pool
  • Automatic styles for header/footer content
  • Do not insert all automatic styles into Writer (CopyAutoStylesToDoc) at once, insert every needed style during loading of <body>

More

Automatic paragraph styles could contain properties (for EditEngine) which are unknown in Writer, e.g.

  • IsNumbering
