The ISOApplet has four type of data structure:
- 1 ElementaryFileTransparent;
2 ElementaryFileLinearFixed;
3 ElementaryFileLinearVariable;
4 ElementaryFileCyclicFixed;
Coding for your needs:
- 1 Reserve the data structure your need, others can be removed.
2 Reserve code in IsoApplet.java for your need, delete unused codes.
sense and simplicity
