C++ (Cpp) referenceTypeTag Examples

Example #1

File: ClassObjectReferenceImpl.c Project: Spencerx/ManagedRuntimeInitiative

static jboolean
reflectedType(PacketInputStream *in, PacketOutputStream *out)
{
    jbyte tag;
    jobject object;
    JNIEnv *env;

    env = getEnv();

    object = inStream_readObjectRef(env, in);
    if (inStream_error(in)) {
        return JNI_TRUE;
    }

    /*
     * In our implementation, the reference type id is the same as the
     * class object id, so we bounce it right back.
     *
     */

    tag = referenceTypeTag(object);
    (void)outStream_writeByte(out, tag);
    (void)outStream_writeObjectRef(env, out, object);

    return JNI_TRUE;
}

Example #2

static void 
writeFieldAccessEvent(JNIEnv *env, PacketOutputStream *out, EventInfo *evinfo)
{
    jbyte fieldClassTag;

    fieldClassTag = referenceTypeTag(evinfo->u.field_access.field_clazz);

    (void)outStream_writeObjectRef(env, out, evinfo->thread);
    writeCodeLocation(out, evinfo->clazz, evinfo->method, evinfo->location);
    (void)outStream_writeByte(out, fieldClassTag);
    (void)outStream_writeObjectRef(env, out, evinfo->u.field_access.field_clazz);
    (void)outStream_writeFieldID(out, evinfo->u.field_access.field);
    (void)outStream_writeObjectTag(env, out, evinfo->object);
    (void)outStream_writeObjectRef(env, out, evinfo->object);
}

Example #3

static void 
writeFieldModificationEvent(JNIEnv *env, PacketOutputStream *out, 
                            EventInfo *evinfo)
{
    jbyte fieldClassTag;

    fieldClassTag = referenceTypeTag(evinfo->u.field_modification.field_clazz);

    (void)outStream_writeObjectRef(env, out, evinfo->thread);
    writeCodeLocation(out, evinfo->clazz, evinfo->method, evinfo->location);
    (void)outStream_writeByte(out, fieldClassTag);
    (void)outStream_writeObjectRef(env, out, evinfo->u.field_modification.field_clazz);
    (void)outStream_writeFieldID(out, evinfo->u.field_modification.field);
    (void)outStream_writeObjectTag(env, out, evinfo->object);
    (void)outStream_writeObjectRef(env, out, evinfo->object);
    (void)outStream_writeValue(env, out, (jbyte)evinfo->u.field_modification.signature_type, 
                         evinfo->u.field_modification.new_value);
}

Example #4

writeClassEvent(JNIEnv *env, PacketOutputStream *out, EventInfo *evinfo)
{
    jbyte classTag;
    jint status;
    char *signature = NULL;
    jvmtiError error;

    classTag = referenceTypeTag(evinfo->clazz);

    if (error != JVMTI_ERROR_NONE) {
        EXIT_ERROR(error,"signature");
    }
    status = classStatus(evinfo->clazz);

    (void)outStream_writeObjectRef(env, out, evinfo->thread);
    (void)outStream_writeByte(out, classTag);
