+ (Object) add_classpath

Rjb::add_classpath(jarname)




# File 'ext/rjb.c'

static VALUE rjb_s_add_classpath(VALUE self, VALUE jarname)
{
    VALUE cpath = rb_cvar_get(self, cvar_classpath);
    SafeStringValue(jarname);
    rb_ary_push(cpath, jarname);
    return cpath;
}

+ (Object) add_jar

Rjb::add_jar(jarname)




# File 'ext/rjb.c'

static VALUE rjb_s_add_jar(VALUE self, VALUE jarname)
{
size_t i;

+ (Object) bind

jclass Rjb::bind(rbobj, interface_name)




# File 'ext/rjb.c'

static VALUE rjb_s_bind(VALUE self, VALUE rbobj, VALUE itfname)
{
VALUE result = Qnil;

if (!ptr->bridge)
{
    free(ptr);
    rjb_check_exception(jenv, 1);
    return Qnil;
}

+ (Object) classes

return all classes that were already loaded. this method simply returns the global hash, but it's safe because the hash was frozen.




# File 'ext/rjb.c'

static VALUE rjb_s_classes(VALUE self)
{
    return rjb_loaded_classes;
}

+ (Object) import

Jclass Rjb::import(classname)




# File 'ext/rjb.c'

static VALUE rjb_s_import(VALUE self, VALUE clsname)
{
JNIEnv* jenv;
jclass jcls;
VALUE v = rb_hash_aref(rjb_loaded_classes, clsname);
if (v != Qnil)
{
return v;
}

+ (Object) load

load Java Virtual Machine def load(class_path = '', vmargs = []) class_path: passes for the class dir and jar name vmargs: strng array of vmarg (such as -Xrs)

change in rjb 0.1.7, omit first argument for JNI version.

because I misunderstood the number means (JVM but JNI).
