public class TreeList
extends AbstractSequence<Object>
implements Appendable, XConsumer, PositionConsumer, Consumable
```
A compact representation of a tree, that is a nested list structure. The data structure can store anything that can be emitted to a Consumer. This data structure is optimized for efficient forwards traversal through the data structure, not random access. It does have an "insertion point"; insertions and deletions are efficient through the use of a buffer gap. It is a reasonable choice for a "DOM" for XML data.

    See Also:
    
    Constant Field Values
  - BEGIN_ATTRIBUTE_LONG
```
protected static final int BEGIN_ATTRIBUTE_LONG
```
    The beginning of an attribute. [BEGIN_ATTRIBUTE_LONG] [index], 2 shorts, where objects[index] is the attribute type name and objects[index+1] is the attribute type object. [end_offset], 2 shorts, giving the location of the following END_ATTRIBUTE. If the attribute straddles the gap, then end_offset is a negative offset relative to data.length. (Therefore allocating more space for the gap does not require adjusting end_offset.) Otherwise, the end_offset is relative to the BEGIN_ATTRIBUTE_LONG word.

```
protected static final int BEGIN_DOCUMENT
```
    Beginning of a document (or top-level value). Used to distinguish a document from its element node. [end_offset], 2 shorts, giving the location of the following END_DOCUMENT. If the attribute straddles the gap, then end_offset is a negative offset relative to data.length. (Therefore allocating more space for the gap does not require adjusting end_offset.) Otherwise, the end_offset is relative to the BEGIN_DOCUMENT word. [parent_offset], in 2 shorts. The parent node, or -1 if no parent. Otherwise, a negative value is a relative offset, while a non-negative value is absolute. (Use the latter when gap is between this node and its parent. The parent would normally be a BEGIN_ENTITY.

    Constant Field Values
  - END_DOCUMENT
```
protected static final int END_DOCUMENT
```
    End of a document.

```
    See Also:
    
    Constant Field Values
  - DOCUMENT_URI
```
protected static final int DOCUMENT_URI
```
    The document-uri property of a node. This is not an actual value, but it is a property of the previous document node, or the surrounding node just after a BEGIN_XXX entry. [DOCUMENT_URI] [index]. 2 shorts, where objects[index] is the document-uri value.
    
    See Also:
    
    Constant Field Values
  - BEGIN_ELEMENT_SHORT
```
protected static final int BEGIN_ELEMENT_SHORT
```
    Beginning of an element, compact form. [BEGIN_ELEMENT_SHORT + index], where objects[index] is the element's type name and objects[index+1] is the type object. [end_offset], the unsigned offset (from the initial word) to the corresponding END_ELEMENT_SHORT. [parent_offset], the (unsigned absolute value of the) offset to the outer BEGIN_ELEMENT_SHORT/BEGIN_ELEMENT_LONG/BEGIN_DOCUMENT. . (If these is no parent, then parent_offset==0.) This should is used when index < BEGIN_ELEMENT_SHORT_INDEX_MAX, both end_offset and parent_offset fit in 16 bits, and the element does not straddle the gap.
    
    See Also:
    
    Constant Field Values
  - BEGIN_ELEMENT_SHORT_INDEX_MAX
```
protected static final int BEGIN_ELEMENT_SHORT_INDEX_MAX
```
    See Also:
    
    Constant Field Values
  - END_ELEMENT_SHORT
```
protected static final int END_ELEMENT_SHORT
```
    End of an element, compact form. [END_ELEMENT_SHORT] [begin_offset], the unsigned absolute value of the offset to the matching BEGIN. (This is the same as the matching end_offset.)
    
    See Also:
    
    Constant Field Values
  - BEGIN_ELEMENT_LONG
```
protected static final int BEGIN_ELEMENT_LONG
```
    Begin of an element, non-compact form. [BEGIN_ELEMENT_LONG] [end_offset], in 2 shorts. The position of the matching END_ELEMENT_LONG. If the element straddles the gap, then end_offset is a negative offset relative to data.length. (Therefore allocating more space for the gap does not require adjusting any end_offset.) If the element and and its children are all on the same side of the gap, then end_offset is a positive offset relative to the BEGIN_ELEMENT_LONG word. (Hence shifting an entire element when the gap is moved does not require changing its end_offset.) Note that the space taken by a BEGIN_ELEMENT_LONG is the same that needed for a BEGIN_ELEMENT_SHORT (but a END_ELEMENT_LONG takes much more space than a END_ELEMENT_SHORT). This is to make it easier to convert a BEGIN_ELEMENT_LONG to a BEGIN_ELEMENT_SHORT or vice versa, as needed.
    
    See Also:
    
    Constant Field Values
  - END_ELEMENT_LONG
```
protected static final int END_ELEMENT_LONG
```
    End of n element, non-compact form. [END_ELEMENT_LONG] [index], 2 shorts where objects[index] is the element's type name and objects[index+1] is the type object. [begin_offset], in 2 shorts. The position of the matching BEGIN_ELEMENT_LONG. If the element straddles the gap, then begin_offset is the actual index (i.e. relative to the start of data) of the matching BEGIN_ELEMENT_LONG. (Therefore allocating more space for the gap does not require adjusting begin_offset.) If the element does not straddle the gap, then begin_offset is a negative offset relative to the END_ELEMENT_LONG word. (Hence shifting an entire element when the gap is moved does not require changing its begin_offset.) relative to data.length. [parent_offset], in 2 shorts. The position of the outer BEGIN_ELEMENT_LONG, BEGIN_ELEMENT_SHORT or BEGIN_DOCUMENT. If the difference straddles the gap (i.e. either this element straddles the gap or the parent element does and the gap precedes this element), then parent_offset is the actual index of the parent element. Otherwise, then parent_offset is a negative offset relative to the END_ELEMENT_LONG word.
