  - addPropertyChangeListener
```
void addPropertyChangeListener(PropertyChangeListener l)
```
    Adds property listener.
  - removePropertyChangeListener
```
void removePropertyChangeListener(PropertyChangeListener l)
```
    Removes property listener.
  - addVetoableChangeListener
```
void addVetoableChangeListener(VetoableChangeListener l)
```
    Adds veto listener.
  - removeVetoableChangeListener
```
void removeVetoableChangeListener(VetoableChangeListener l)
```
    Removes veto listener.
  - isValid
```
boolean isValid()
```
    Test whether the support is in valid state or not. It could be invalid after deserialization when the object it referenced to does not exist anymore.
    
    Returns:
    
    true or false depending on its state
  - isModified
```
boolean isModified()
```
    Test whether the object is modified or not.
    
    Returns:
    
    true if the object is modified
  - markModified
```
void markModified()
           throws IOException
```
    Support for marking the environement modified.
    
    Throws:
    
    IOException - if the environment cannot be marked modified (for example when the file is readonly), when such exception is the support should discard all previous changes
  - unmarkModified
```
void unmarkModified()
```
    Reverse method that can be called to make the environment unmodified.
  - findCloneableOpenSupport
```
CloneableOpenSupport findCloneableOpenSupport()
```
    Method that allows environment to find its cloneable open support.
