Package com.rubecula.spreadsheet Description

Spreadsheet Package: sample application for JQuantity.

This spreadsheet application is designed and implemented solely as a sample application for the JQuantity package. It does not purport to be a particularly good nor useful spreadsheet, although it does work. The quality of the Javadoc and adherence to good programming practices are distinctly sub-par.

Use at your own risk.

It is implemented in Swing.

Invoking the spreadsheet

The SampleApplication.main method takes four optional string run-time arguments:

1. "debug": if this argument is present, various debug statements are turned on, especially in the area of expression parsing and evaluation.
2. "JEP": if this argument is present, the JEP expression parser will be used to parse expressions which cannot be parsed by the native parser of the spreadsheet package. The com.rubecula.jep package must be available, as must the jep.jar.
3. This is the name of a spreadsheet file which will be automatically opened at startup, assuming it exists.
4. If the previous argument is present, this is the name of a file to which the opened spreadsheet will be immediately saved after startup.

Dependencies

This package requires Java 1.3.1 or above.

The following non-standard packages are required at compile time:

• com.rubecula.util

The following classes will be loaded at runtime:

• com.rubecula.jquantity.PresentationFactory;
• com.rubecula.math.MillFactory;
• com.rubecula.jep.ExpressionParser (if JEP is used).
