public interface ADQLObject
```
This class gathers all main behaviors of any ADQL object (query, clause, columns, condition, etc...):
- to have a name in ADQL
- to be written in ADQL
- to offer a way to search any ADQL item (included itself)
- to get its position in the original ADQL query.

- Method Detail
  - getName
```
java.lang.String getName()
```
    Gets the name of this object in ADQL.
    
    Returns:
    
    The name of this ADQL object.
  - getPosition
```
TextPosition getPosition()
```
    Gets the position of this object/token in the ADQL query.
    
    By default, no position should be set.

  - toADQL
```
java.lang.String toADQL()
```
    Gets the ADQL expression of this object.
    
    Returns:
    
    The corresponding ADQL expression.
  - getCopy
```
ADQLObject getCopy()
            throws java.lang.Exception
```
    Gets a (deep) copy of this ADQL object.
    
    Returns:
    
    The copy of this ADQL object.
    
    Throws:
    
    java.lang.Exception - If there is any error during the copy.
  - adqlIterator
```
ADQLIterator adqlIterator()
```
    Gets an iterator on the intern ADQL objects.
    
    Note:The returned iterator is particularly used by a ISearchHandler extension to browse a whole ADQL tree.
    
    Returns:
    
    An ADQL objects iterator.
