solve()

UICoord solve ( LocationRule const &  rule, size_t  depth, Literal  elementTypeID  )

inline

Solve for a location according to the given location rule.

Parameters

depth	desired kind of UI element (and thus the depth in the UI topology tree)
elementType	designator of the specific element to be created at that level

Returns

an explicit location, resolved against the current UI topology. May be empty

Remarks

the returned path is either empty (no solution exists), or it is "partially covered" by the existing UI; here, the "covered" part are the already existing UI elements, while the remaining, uncovered extension describes additional elements to be created. When the resolution process found an already existing UI element, the returned path is completely covered. The degree of coverage of a path can be found out with the help of a UICoordResolver, which also needs a LocationQuery (service) to discover the currently existing UI topology.

preprocess()

void preprocess ( UICoordResolver &  builder, LocationClause const &  clause  )

inlineprivate

perform adjustments on the current pattern to support some very specific situations

• when we want to create a new panel (or re-use an existing of the same name), on top of an existing (but irrelevant) perspective, we mark this perspective as "just there". This allows to get a new path as solution, which is just covered up to and including that perspective; without special treatment, such a match would otherwise be rejected.
