UICoord Class Reference

#include "stage/interact/ui-coord.hpp"

Description

Describe a location within the UI through structural/topological coordinates.

A UICoord specification is a sequence of Literal tokens, elaborating a path descending through the hierarchy of UI elements down to the specific UI element to refer.

Constructor & Destructor Documentation

◆ UICoord() [1/2]

UICoord ( ARGS &&...  args)
inlineexplicit

UI-Coordinates can be created explicitly by specifying a sequence of Literal tokens, which will be used to initialise and then normalise the underlying PathArray.

Warning
Literal means _"literal"_ with guaranteed storage during the whole execution.
Remarks
- in case you need to construct some part, then use Symbol to intern the resulting string into the global static SymbolTable.
  • usually the Builder API leads to more readable definitions, explicitly indicating the meaning of the coordinate's parts.

Definition at line 154 of file ui-coord.hpp.

References UICoord::currentWindow(), UICoord::firstWindow(), UICoord::path(), UICoord::persp(), and UICoord::window().

+ Here is the call graph for this function:

◆ UICoord() [2/2]

UICoord ( Builder &&  builder)
inline

shortcut to allow init from builder expression

Note
this ctor is used to "fix" and normalise the contents established in the Builder thus far.

Definition at line 667 of file ui-coord.hpp.

Member Function Documentation

◆ currentWindow()

UICoord::Builder currentWindow ( )
inlinestatic

Builder: start definition of UI-Coordinates rooted in the currentWindow

Returns
a minimally defined Builder, allowing to define further parts; to finish the definition, cast / store it into UICoord, which itself is immutable.

Definition at line 678 of file ui-coord.hpp.

References UICoord::window().

Referenced by UICoord::UICoord().

+ Here is the caller graph for this function:

◆ window()

UICoord::Builder window ( Literal  windowID)
inlinestatic

Builder: start definition of UI-Coordinates rooted in given window.

Returns
a Builder with just the windowID defined

Definition at line 691 of file ui-coord.hpp.

Referenced by UICoord::currentWindow(), UICoord::firstWindow(), and UICoord::UICoord().

+ Here is the caller graph for this function:

◆ persp()

UICoord::Builder persp ( Literal  perspectiveID) const
inline
Returns
a Builder holding a clone copy of the original UICoord, with the perspective information set to a new value.
Remarks
This Builder can then be used do set further parts independently of the original. When done, store it as new UICoord object. To achieve real mutation, assign it to the original variable.

+ Here is the caller graph for this function:

◆ path()

UICoord::Builder path ( Literal  pathDefinition) const
inline

convenience builder function so set a full path definition

Note
the given path string will be split at `'/'` and the resulting components will be stored/retrieved as Symbol

Definition at line 745 of file ui-coord.hpp.

References UICoord::Builder.

Referenced by UICoord::UICoord().

+ Here is the caller graph for this function:

◆ isIncomplete()

bool isIncomplete ( ) const
inline
Remarks
incomplete UI-Coordinates have some fragment of the path defined, but lacks the definition of an anchor point, i.e. it has no window ID

Definition at line 215 of file ui-coord.hpp.

Referenced by UICoord::Builder::prepend().

+ Here is the caller graph for this function:

◆ isExplicit()

bool isExplicit ( ) const
inline
Remarks
an explicit coordinate spec does not use wildcards and is anchored in a window spec

Definition at line 234 of file ui-coord.hpp.

◆ isExtendedBelow()

bool isExtendedBelow ( UICoord const &  parent) const
inline

Check if this coordinate spec can be seen as an extension of the given parent coordinates and thus reaches further down towards specific UI elements in comparison to the parent path This constitutes a partial order, since some paths might just be totally unrelated to each other and thus not comparable.

Note
we tolerate (but not demand) expansion/interpolation of the given parent, i.e. parent may be incomplete or contain `'*'` placeholders.
Todo:
10/2017 have to verify suitability of this definition

Definition at line 271 of file ui-coord.hpp.

◆ setTailSequence() [1/2]

void setTailSequence ( size_t  idx,
Literal  newContent 
)
inlineprivate

replace / overwrite existing content starting at given index.

Parameters
idxwhere to start adding content; storage will be expanded to accommodate
newContenteither a single element, or several elements delimited by `'/' @note - a path sequence will be split at'/'` and the components interned
  • any excess elements will be cleared
Warning
need to invoke PathArray::normalise() afterwards

Definition at line 423 of file ui-coord.hpp.

Referenced by UICoord::Builder::path().

+ Here is the caller graph for this function:

◆ setTailSequence() [2/2]

void setTailSequence ( size_t  idx,
std::vector< Literal > &  pathElms 
)
inlineprivate

replace the existing path information with the given elements

Note
- storage will possibly be expanded to accommodate
  • the individual path elements are required to persist
  • any excess elements will be cleared
  • the pathElms can be empty in which case just any content starting from idx will be cleared
Warning
need to invoke PathArray::normalise() afterwards
