```
    Parameters:
    
    constraints - List of strings representing the constraints we want to set (empty means ALL).
    
    deferred - Encodes IMMEDIATE (false) or DEFERRED (true)
    
    cm - The context manager

    Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.
    
    Overrides:
    
    toString in class StatementNode
    
    Returns:
    
    This object as a String
  - formatList

    Create the Constant information that will drive the guts of Execution.
    
    Overrides:
    
    makeConstantAction in class QueryTreeNode
    
    Throws:
    
    StandardException - Thrown on failure
  - bindStatement
```
public void bindStatement()
                   throws StandardException
```
    Description copied from class: StatementNode
    
    Perform the binding operation statement. Binding consists of permissions checking, view resolution, datatype resolution, and creation of a dependency list (for determining whether a tree or plan is still up to date). This bindStatement() method does nothing. Each StatementNode type that can appear at the top of a tree can override this method with its own bindStatement() method that does "something".
    
    Overrides:
    
    bindStatement in class StatementNode
    
    Throws:
    
    StandardException - Thrown on error
  - acceptChildren
```
void acceptChildren(Visitor v)
             throws StandardException
```
    Description copied from class: QueryTreeNode
    
    Accept a visitor on all child nodes. All sub-classes that add fields that should be visited, should override this method and call accept(v) on all visitable fields, as well as super.acceptChildren(v) to make sure all visitable fields defined by the super-class are accepted too.
    
    Overrides:
    
    acceptChildren in class QueryTreeNode
    
    Parameters:
    
    v - the visitor
    
    Throws:
    
    StandardException - on errors raised by the visitor
