SpaceSpecifier
public SpaceSpecifier(boolean startsReferenceArea)
- Creates a new SpaceSpecifier.
- Parameters:
startsReferenceArea
- true if it starts a new reference area
clone
public java.lang.Object clone()
- Overrides:
clone
in class java.lang.Object
- See Also:
Object.clone()
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 moreSpace)
- 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.
resolve
public MinOptMax resolve(boolean endsReferenceArea)
- Resolve the current sequence of space-specifiers, accounting for
forcing values.
- Parameters:
endsReferenceArea
- True if 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:
