Configuring a Unique Attributes Recognizer

The ro.sync.ecss.extensions.api.UniqueAttributesRecognizer interface can be implemented if you want to provide for your framework the following features:

• Automatic ID generation - You can automatically generate unique IDs for newly inserted elements. Implementations are already available for the DITA and DocBook frameworks. The following methods can be implemented to accomplish this: assignUniqueIDs(int startOffset, int endOffset), isAutoIDGenerationActive()
• Avoiding copying unique attributes when "Split" is called inside an element - You can split the current block element by pressing the "Enter" key and then choosing "Split". This is a very useful way to create new paragraphs, for example. All attributes are by default copied on the new element but if those attributes are IDs you sometimes want to avoid creating validation errors in the editor. Implementing the following method, you can decide whether or not an attribute should be copied during the split: boolean copyAttributeOnSplit(String attrQName, AuthorElement element)

  Tip

  The ro.sync.ecss.extensions.commons.id.DefaultUniqueAttributesRecognizer class is an implementation of the interface that can be extended by your customization to provide easy assignation of IDs in your framework. You can also check out the DITA and DocBook implementations of ro.sync.ecss.extensions.api.UniqueAttributesRecognizer to see how they were implemented and connected to the extensions bundle.
