Enhancement Request Merge #14
Description
Why? so you can merge two json objects and preserve the previous ones data. Note that JSONObject and JSONArray both Implement ICopy.
Code JSONObject:
public void merge(JSONObject other) { for(java.util.Map.Entry<Object, Object> entry : other.entrySet()) { String key = (String) entry.getKey(); Object otherIndex = entry.getValue(); Object thisIndex = this.get(key); if(thisIndex instanceof JSONObject && otherIndex instanceof JSONObject) { JSONObject json = (JSONObject) thisIndex; json.merge((JSONObject) otherIndex); } else if(thisIndex instanceof JSONArray && otherIndex instanceof JSONArray) { JSONArray arr = (JSONArray) thisIndex; arr.merge((JSONArray) otherIndex); } else { this.put(key, otherIndex instanceof ICopy ? ((ICopy) otherIndex).copy() : otherIndex); } } } @Override public JSONObject copy() { JSONObject json = new JSONObject(this.size() + 3); for(java.util.Map.Entry<Object, Object> entry : this.entrySet()) { String key = (String) entry.getKey(); Object value = entry.getValue(); if(value instanceof ICopy) json.put(key, ((ICopy) value).copy()); else json.put(key, value); } return json; }Code JSONArray:
public void merge(JSONArray other) { int tsize = this.size(); for(int i=0; i< other.size(); i++) { Object otherIndex = other.get(i); if(i < tsize) { Object thisIndex = this.get(i); if(thisIndex instanceof JSONArray && otherIndex instanceof JSONArray) { ((JSONArray)thisIndex).merge((JSONArray) otherIndex); } else if(thisIndex instanceof JSONObject && otherIndex instanceof JSONObject) { ((JSONObject)thisIndex).merge((JSONObject) otherIndex); } else this.set(i, otherIndex instanceof ICopy ? ((ICopy) otherIndex).copy() : otherIndex); } else this.add(otherIndex instanceof ICopy ? ((ICopy) otherIndex).copy() : otherIndex); } } @Override public JSONArray copy() { JSONArray arr = new JSONArray(this.size() + 3); for(int i=0;i<this.size();i++) { Object o = this.get(i); if(o instanceof ICopy) o = ((ICopy) o).copy(); arr.add(o); } return arr; }Code ICopy:
public interface ICopy{ public ICopy copy(); }Current Issue: if the original's data type doesn't match the other's data type it gets replaced with a copy of the other JSON's data. JSONObject != JSONArray and other JSONObject has a JSONArray at that key then JSONArray replaces JSONObject. A possible solution would be to wrap the JSONObject or JSONArray when that happens according to chatgpt. I wouldn't recommend throwing an error as this is SIMPLE JSON and SIMPLE json isn't suppose to be as strict.
