The `print_jvm_class` Command

Usage

`print_jvm_class [options] <Path>[.class]`

Command `print_jvm_class` prints a human readable version of the <Path> class file. Printing is done on standard output. This command was developed to check the byte code produced by command `compile_to_jvm`. It is useful only if you want to have a close look at the generated Java byte code.

This command may also be used to print Java byte code you obtained with Java compilers, such as `javac`. We find the output of `print_jvm_class` more readable than the output of `javap`.

Options

-help:
  Display a brief summary of the command-line syntax and a complete list of print_jvm_class options.
-verbose:
  Print additional informations.
-version:
  Show the number of the version of SmartEiffel you're using.

Examples

First, you have to produce some class files using command `compile_to_jvm`:

  `compile_to_jvm -boost hello_world`

Then, using command `print_to_jvm_class` you can print on standard output a readable view of any produced class file. The following command prints the main class:

  `print_jvm_class hello_world.class`

You can also print any class file of the hello_world directory. For example, under Unix, you can print the byte code produced for class INTEGER using command:

  `print_jvm_class hello_world/integer.class`
