All Implemented Interfaces:

java.lang.Cloneable
```
public class SpaceSpecifier
extends java.lang.Object
implements java.lang.Cloneable
```
Accumulate a sequence of space-specifiers (XSL space type) on areas with a stacking constraint. Provide a way to resolve these into a single MinOptMax value.

- Constructor Detail
  - SpaceSpecifier
```
public SpaceSpecifier(boolean startsReferenceArea)
```
    Creates a new SpaceSpecifier.
    
    Parameters:
    
    startsReferenceArea - true if it starts a new reference area
- Method Detail
  - clone
```
public java.lang.Object clone()
```
    Overrides:
    
    clone in class java.lang.Object
  - clear
```
public void clear()
```
    Clear all space specifiers
  - hasSpaces
```
public boolean hasSpaces()
```
    Indicates whether any space-specifiers have been added.
    
    Returns:
    
    true if any space-specifiers have been added.
  - addSpace
```
public void addSpace(SpaceVal space)
```
    Add a new space to the sequence. If this sequence starts a reference area, and the added space is conditional, and there are no non-conditional values in the sequence yet, then ignore it. Otherwise add it to the sequence.
    
    Parameters:
    
    space - the space to add.
  - resolve
```
public MinOptMax resolve(boolean endsReferenceArea)
```
    Resolve the current sequence of space-specifiers, accounting for forcing values.
    
    Parameters:
    
    endsReferenceArea - whether the sequence should be resolved at the trailing edge of reference area.
    
    Returns:
    
    the resolved value as a min/opt/max triple.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
