public abstract class AbstractFormattedWalker
extends java.lang.Object
implements Walker
```
This Walker implementation walks a list of Content in a Formatted form of some sort.
The JDOM content can be loosely categorised in to 'Text-like' content (consisting of Text, CDATA, and EntityRef), and everything else. This distinction is significant for for this class and it's sub-classes.
There will be text manipulation, and some (but not necessarily all) Text-like content will be returned as text() instead of next().
The trick in this class is that it deals with the regular content, and delegates the Text-like content to the sub-classes.
Subclasses are tasked with analysing chunks of Text-like content in the analyzeMultiText(MultiText, int, int) method. The subclasses are responsible for adding the relevant text content to the suppliedMultiText instance in such a way as to result in the correct format.
The Subclass needs to concern itself with only the text portion because this abstract class will ensure the Text-like content is appropriately indented.

`boolean`	`hasNext()` Behaves similarly to to a regular Iterator
`boolean`	`isAllText()` If all the content in this walker is empty, or if whatever content is available is Text-like.
`boolean`	`isAllWhitespace()` If all the content is Text-like (`Walker.isAllText()` returns true), and additionally that any content is either Text or CDATA, and that the values of these Text/CDATA members are all XML Whitespace.
`boolean`	`isCDATA()` If the previous next() method returned null, then this will indicate whether the current text() value is CDATA or regular Text.
`Content`	`next()` Similar to an Iterator, but null return values need special treatment.
`java.lang.String`	`text()` If the previous call to next() returned null, then this will return the required text to be processed.

public AbstractFormattedWalker(java.util.List<? extends Content> xx,
                               FormatStack fstack,
                               boolean doescape)
```
    Create a Walker that preserves all content in its raw state.
    
    参数:
    
    xx - the content to walk.
    
    fstack - the current FormatStack
    
    doescape - Whether Text values should be escaped.

  - next
```
public final Content next()
```
    从接口复制的说明: Walker
    
    Similar to an Iterator, but null return values need special treatment.
    
    指定者:
    
    next 在接口中 Walker
    
    返回:
    
    the next content to be processed, perhaps null if the next content is re-formatted text of some sort (Text / CDATA).
  - isAllText
```
public final boolean isAllText()
```
    从接口复制的说明: Walker
    
    If all the content in this walker is empty, or if whatever content is available is Text-like.
    Text-like content is considered to be Text, CDATA, EntityRef, or any (potentially mixed) sequence of these types, but no other types.
    
    指定者:
    
    isAllText 在接口中 Walker
    
    返回:
    
    true if there is no content, or all content is Text
  - hasNext
```
public final boolean hasNext()
```
    从接口复制的说明: Walker
    
    Behaves similarly to to a regular Iterator
    
    指定者:
    
    hasNext 在接口中 Walker
    
    返回:
    
    true if there is more content to be processed
  - text
```
public final java.lang.String text()
```
    从接口复制的说明: Walker
    
    If the previous call to next() returned null, then this will return the required text to be processed. Check to see whether this text is CDATA by calling the isCDATA() method.
    
    指定者:
    
    text 在接口中 Walker
    
    返回:
    
    The current text value (null if the previous invocation of next() returned a non-null value).
  - isCDATA
```
public final boolean isCDATA()
```
    从接口复制的说明: Walker
    
    If the previous next() method returned null, then this will indicate whether the current text() value is CDATA or regular Text.
    
    指定者:
    
    isCDATA 在接口中 Walker
    
    返回:
    
    true if the current text() is valid, and is CDATA.
  - isAllWhitespace
```
public final boolean isAllWhitespace()
```
    从接口复制的说明: Walker
    
    If all the content is Text-like (Walker.isAllText() returns true), and additionally that any content is either Text or CDATA, and that the values of these Text/CDATA members are all XML Whitespace.
    
    指定者:
    
    isAllWhitespace 在接口中 Walker
    
    返回:
    
    true
