    Since:
    
    0.9.7

java.util.Map<java.lang.String,java.lang.Object> toProperties(boolean storeDefaults)
```
    A properties representation of this Configuration. Note that changes made to this properties object will not be automatically reflected in this Configuration object.
    
    Parameters:
    
    storeDefaults - if true, then properties will be written out even if they match the default value for a property
  - getPropertyKeys
```
java.util.List<java.lang.String> getPropertyKeys(java.lang.String propertyName)

void fromProperties(java.util.Map map)
```
    Set this Configuration via the given map. Any keys missing from the given map will not be set. Note that changes made to this map will not be automatically reflected in this Configuration object. IMPORTANT: If the map contains instantiated objects(rather than string values), only the string representation of those objects are considered in this configuration's equals and hashCode methods. If the object's property has no string form(such as an ObjectValue), the object is not part of the equality and hashing calculations.
  - addPropertyChangeListener
```
void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

```
void removePropertyChangeListener(java.beans.PropertyChangeListener listener)
```
    Removes a listener for any property changes.
    
    Parameters:
    
    listener - the listener to remove
  - setReadOnly
```
void setReadOnly(int readOnly)
```
    Lock down the configuration's state. Attempting to set state on a read-only configuration results in an exception.
  - isReadOnly
```
boolean isReadOnly()
```
    Return true if this configuration is immutable.
  - instantiateAll
```
void instantiateAll()
```
    Call the instantiating get methods for all values. Up-front instantiation allows one to avoid the synchronization necessary with lazy instantiation.
  - close
```
void close()
```
    Free the resources used by this object.
    
    Specified by:
    
    close in interface Closeable
  - clone
```
java.lang.Object clone()
```
    Return a copy of this configuration.

```
java.lang.ClassLoader getUserClassLoader()
```
    Gets a class loader that can be additionally used to load custom plugin values.
    
    Returns:
    
    an additional classloader for loading custom plugins. Can be null.
    
    Since:
    
    2.3.0
    
    See Also:
    
    Configurations.newInstance(String, ClassLoader)
  - setUserClassLoader
```
void setUserClassLoader(java.lang.ClassLoader loader)
```
    Sets an additional classloader to load custom plugin values. In OSGi environment, we internally set the bundle class loader as the user class loader.
    
    Parameters:
    
    loader - a class loader to load custom plugin values
    
    Since:
    
    2.3.0
