For the BrailleBlaster project, the editor and user interface are
written in Java. The braille knowledge needed for translating annd
formatting is in the C library liblouisutdml. The two communicate by
method calls and xml documents. We would like to pass the documennts
back and forth inn a memory buffer, if possible. However, some
doccuments can be quite large, up to 6 megabytes. After UTDML (Unified
Tactile Document Markup Language) has been added to them they can be 20
MB or more. Such large buffers seem impractical, so we will probably
have to pass documents of that size as files. However, we would like to
be able to pass smaller documents, say up to 100k, in memory. How can
this best be done on the Java end? liblouisutdml expects xml documents
in UTF-8 in an array of 8-bit charactors.
Thanks,
John
