Generate CFI from html in Java

[romaingiard]

Hello,

Is it possible to generate CFI in java ? I want to develop a search function for epubs in Android Side (the html/xhtml content are in a SQL Lite FTS table), generate CFI for results and highlights results found.

• I've seen in SDK a class CFI.java which is empty.

Thank you for your help.

There is some native C++ code in ReadiumSDK, but you would need to write JNI wrappers yourself I am afraid.

Note that the Javascript Readium implementation of CFI is actively used ( https://github.com/readium/readium-cfi-js + https://github.com/readium/readium-shared-js/blob/develop/js/views/cfi_navigation_logic.js ), but I am not so sure about the status / usage / relevance of the C++ implementation.
