    the Blob value or null.
  - getDate
```
public Date getDate(String key)
```
    Gets a property's value as a Date. JSON does not directly support dates, so the actual property value must be a string, which is then parsed according to the ISO-8601 date format (the default used in JSON.) Returns null if the value doesn't exist, is not a string, or is not parseable as a date. NOTE: This is not a generic date parser! It only recognizes the ISO-8601 format, with or without milliseconds.
    
    Overrides:
    
    getDate in class ReadOnlyDictionary
    
    Parameters:
    
    key - the key

    the Date value or null.
  - toMap
```
public Map<String,Object> toMap()
```
    Gets content of the current object as an Map. The values contained in the returned Map object are all JSON based values.
    
    Overrides:
    
    toMap in class ReadOnlyDictionary
    
    Returns:
    
    the Map object representing the content of the current object in the JSON format.
  - contains
```
public boolean contains(String key)
```
    Tests whether a property exists or not. This can be less expensive than getObject(String), because it does not have to allocate an Object for the property value.
    
    Overrides:
    
    contains in class ReadOnlyDictionary
    
    Parameters:
    
    key - the key
    
    Returns:
    
    the boolean value representing whether a property exists or not.

```
    Overrides:
    
    setC4Doc in class ReadOnlyDocument
    
    Throws:
