- Method Detail
  - getText
```
java.lang.String getText()
```
    Returns a textual representatio of the span, suitable for XML output, e.g.
  - intersection
```
Span intersection(Span r)
```
    Returns a new span that is the intersection of this span and another.
  - getDocument
```
java.lang.Object getDocument()
```
  - intersects
```
boolean intersects(Span r)
```
  - isSubspan
```
boolean isSubspan(Span r)
```
  - getStartIdx
```
int getStartIdx()
```
    Returns an integer index identifying the start of this span. Beware that in some cases (e.g., for images), this may not correspond directly to a sequence index.
  - getEndIdx
```
int getEndIdx()
```
    Returns an integer index identifying the end of this span. Beware that in some cases (e.g., for images), this may not correspond directly to a sequence index.
