/** @file view-locator.cpp
|
|
** Implementation details of a machinery to allocate UI global component views.
|
|
** Essentially this compilation unit hosts the implementation backing the [ViewSpec-DSL](view-spec-dsl.hpp)
|
|
** and the [Location Solver](ui-location-solver.hpp) to drive evaluation of the standard location defaults,
|
|
** which are [hard-wired into the UI](\ref id-scheme.hpp). For this integration of various facilities and
|
|
** frameworks we rely on actual definitions for the DSL-tokens, which themselves are functors and tied by
|
|
** lambda-binding into the implementation side of ViewLocator; which both acts as a front-end to access
|
|
** the service to "get or create" a component and also holds the UILocationSolver component to perform
|
|
** the actual location solving mechanism. The DSL thus sits between both poles, since _resolving a view_
|
|
** draws upon the default locating configuration encoded as DSL tokens, which in turn call back into
|
|
** the implementation services within ViewLocator to resolve those partial location specifications
|
|
** against the currently existing UI topology and then to access or create new UI components as
|
|
** laid out through those definitions.
