- Method Detail
  - belongsTo
```
float belongsTo(Area node)
```

    Parameters:
    
    node - The examined area node.
    
    Returns:
    
    the relevance of the assignment (0.0 = not assigned, 0.1 = hopefully possible, >0.5 quite possible, 1.0 absolutely sure)
  - allowsContinuation
```
boolean allowsContinuation(Area node)
```
    Checks whether the area may be a continuation of a previously started area tagged with this tag.
    
    Parameters:

    Returns:
    
    true if the area may be a continuation of a tagged area
  - allowsJoining
```
boolean allowsJoining()
```
    Checks whether the tag may be used for joining the areas in the visual area tree.

    true if the tag may be used for joining.
  - mayCoexistWith
```
boolean mayCoexistWith(Tag other)
```
    Check if the area tagged with this tag may be tagged with another tag. If not, this tag won't be used for the areas already tagged with another tag.
  - extract
```
List<TagOccurrence> extract(String src)
```
    Extracts the parts of a source string that correspond to this tag.
