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
