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 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:
toString in class java.lang.Object
