```
public AbstractProperty()
```
- Method Detail
  - isReadOnly
```
public boolean isReadOnly()
```
    Tests if the Property is in read-only mode. In read-only mode calls to the method setValue will throw ReadOnlyException and will not modify the value of the Property. Override for additional restrictions on what is considered a read-only property.
    
    Specified by:
    
    isReadOnly in interface Property<T>
    
    Returns:
    
    true if the Property is in read-only mode, false if it's not
  - setReadOnly
```
public void setReadOnly(boolean newStatus)
```
    Description copied from interface: Property
    
    Sets the Property's read-only mode to the specified status. This functionality is optional, but all properties must implement the isReadOnly mode query correctly.
    
    Specified by:
    
    setReadOnly in interface Property<T>
    
    Parameters:
    
    newStatus - new read-only status of the Property
  - toString
```
@Deprecated
public String toString()
```
    Deprecated. As of 7.0. To get the property value, use Property.getValue() instead (and possibly toString on that)
    
    Returns a string representation of this object. The returned string representation depends on if the legacy Property toString mode is enabled or disabled.
    If legacy Property toString mode is enabled, returns the value of the Property converted to a String.
    
    If legacy Property toString mode is disabled, the string representation has no special meaning
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    A string representation of the value value stored in the Property or a string representation of the Property object.
