Knowledge Base - Annotation Properties

You can get the annotation's author using the following method:

/**
* get annotation's popup text, mostly it means the author.
* if this annotation is popup annotation, it get parent annotation's label.
* this method require professional or premium license.
* @return text string or null if failed.
*/

final public String GetPopupLabel() {} 

If you have a premium license, you can use the advanced properties to get more data about the annotation, like the creation date, modification date...etc.

To use the advanced properties, you can do something like the following, and call checkAnnotAdvancedProp:

static private String m_types[] = new String[]{"null", "boolean", "int", "real", "string", "name", "array", "dictionary", "reference", "stream"};
static private String get_type_name(int type)
{
if(type >= 0 && type < m_types.length) return m_types[type];
else return "unknown";
}


private void checkAnnotAdvancedProp(Annotation annot) {
if(annot == null) return;

handleRef(annot.Advance_GetRef());
}

private void handleRef(Ref ref) {
if(ref != null) {
Obj obj = m_doc.Advance_GetObj(ref);
handleDictionary(obj);
}
}

private void handleDictionary(Obj obj) {
int count = obj.DictGetItemCount();
for(int cur = 0; cur < count; cur++) {
String tag = obj.DictGetItemTag(cur);
Obj item = obj.DictGetItem(cur);
int type = item.GetType();
String type_name = get_type_name(type);

Log.i("--ADV--","tag:" + cur + "---" + tag + ":" + type_name + " ->");

if(type == 1) //boolean
Log.i("--ADV--"," value = " + item.GetBoolean());
else if(type == 2) //int
Log.i("--ADV--"," value = " + item.GetInt());
else if(type == 3) //real
Log.i("--ADV--"," value = " + item.GetReal());
else if(type == 4) //string
Log.i("--ADV--"," value = " + item.GetTextString());
else if(type == 5) //name
Log.i("--ADV--"," value = " + item.GetName());
else if(type == 6) { //array
int arraycount = item.ArrayGetItemCount();
for(int k = 0; k < arraycount; k++) {
Obj array_obj = item.ArrayGetItem(k);
Log.i("--ADV--","array item " + k + ": value = " + array_obj.GetReal());
}
}
else if (type == 7) //dictionary
handleDictionary(item);
}
}
