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.

clone
public java.lang.Object clone()
- Overrides:
clone
in classjava.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.
