Examples of serp.bytecode.Code.constant()

serp.bytecode.Code.constant()
Load some constant onto the stack. The {@link ConstantInstruction}type takes any constant and correctly translates it into the proper opcode, depending on the constant type and value. For example, if the constant value is set to 0L, the opcode will be set to lconst0.

        // awhite: the above should work, but I'm seeing a messed up situation
        // all of a sudden where when a subclass calls this method, it somehow
        // happens before <clinit> is ever invoked, and so our
        // pcInheritedFieldCount field isn't initialized!  so instead,
        // return <fields> + <superclass>.pcGetManagedFieldCount ()
        code.constant().setValue(_meta.getDeclaredFields().length);
        if (_meta.getPCSuperclass() != null) {
            Class superClass = getType(_meta.getPCSuperclassMetaData());
            String superName = getCreateSubclass() ?
                PCEnhancer.toPCSubclassName(superClass) :
                superClass.getName();
