public ConstraintDescriptorList()
```
- Method Detail
  - setScanned
```
public void setScanned(boolean scanned)
```
    Mark whether or not the underlying system table has been scanned. (If a table does not have any constraints then the size of its CDL will always be 0. We used these get/set methods to determine when we need to scan the table.
    
    Parameters:
    
    scanned - Whether or not the underlying system table has been scanned.
  - getScanned
```
public boolean getScanned()
```
    Return whether or not the underlying system table has been scanned.
    
    Returns:
    
    Where or not the underlying system table has been scanned.
  - getConstraintDescriptor
```
public ConstraintDescriptor getConstraintDescriptor(UUID indexUUID)
```
    Get the ConstraintDescriptor with the matching UUID String for the backing index.
    
    Parameters:
    
    indexUUID - The UUID for the backing index.
    
    Returns:
    
    The matching ConstraintDescriptor.
  - getConstraintDescriptorById
```
public ConstraintDescriptor getConstraintDescriptorById(UUID uuid)
```
    Get the ConstraintDescriptor with the matching constraint id.
    
    Parameters:
    
    uuid - The constraint id.
    
    Returns:
    
    The matching ConstraintDescriptor.
  - dropConstraintDescriptorById
```
public ConstraintDescriptor dropConstraintDescriptorById(UUID uuid)
```
    Drop the constraint with the given UUID.
    
    Parameters:
    
    uuid - The constraint id.
    
    Returns:
    
    The matching ConstraintDescriptor.
  - getConstraintDescriptorByName
```
public ConstraintDescriptor getConstraintDescriptorByName(SchemaDescriptor sd,
                                                          java.lang.String name)
```
    Get the ConstraintDescriptor with the matching constraint name.
    
    Parameters:
    
    sd - The constraint schema descriptor.
    
    name - The constraint name.
    
    Returns:
    
    The matching ConstraintDescriptor.
  - getPrimaryKey
```
public ReferencedKeyConstraintDescriptor getPrimaryKey()
```
    Get the ConstraintDescriptor with the matching constraint name.
    
    Returns:
    
    The matching ConstraintDescriptor.
  - getConstraintDescriptorList
```
public ConstraintDescriptorList getConstraintDescriptorList(boolean enforced)
```
    Return a list of constraints where enforced is as passed in.
    
    Parameters:
    
    enforced - true or false
    
    Returns:
    
    a constraint descriptor list built from this. Always a new list even if all the elements in this were of the correct type (i.e. not optimized for the case where every element is desired).
  - elementAt
```
public ConstraintDescriptor elementAt(int n)
```
    Return the nth (0-based) element in the list.
    
    Parameters:
    
    n - Which element to return.
    
    Returns:
    
    The nth element in the list.
  - getSubList
```
public ConstraintDescriptorList getSubList(int type)
```
    Return a ConstraintDescriptorList containing the ConstraintDescriptors of the specified type that are in this list.
    
    Parameters:
    
    type - The constraint type.
    
    Returns:
    
    A ConstraintDescriptorList containing the ConstraintDescriptors of the specified type that are in this list.
