The Dictionary Parser is defined by the VvidgetCodeDictionaryParser class. An instance of that class is used to aid in the construction of a dictionary which defines a graph.
Add the Dictionary Parser functionality to your project by adding all the headers in /Library/Vvidget/ios/include to your project and one of the libraries referenced below for a specific build Configuration.
| Definition: | /Library/Vvidget/ios/include/VvidgetCodeDictionaryParser.h |
| Device Implementation: | /Library/Vvidget/ios/lib/device/libVvidget.a |
| Simulator Implementation: | /Library/Vvidget/ios/lib/simulator/libVvidget.a |
The following defines each method that is used with an object (instance) of the VvidgetCodeDictionaryParser type.
- (id)init
|
You will need to make at least one dictionary parser for your application. The following makes a dictionary parser:
The newly constructed object is assigned to the symbol |
- (void)VC_associate_with_view:(id)the_view
|
The parser translates a dictionary state to an object graph whose root is an element of the_view. This method associates this parser with the_view. the_view is an instance of class VvidgetCodeView. See View.
|
- (void)VC_update_using_dictionary_constructor:(VvidgetCodeDictionaryConstructor *)the_constructor
|
This method parses the_constructor to the view associated with the receiver. Once this method is called the dictionary state is mapped to a "live" object graph state and the view is ready for display and other interactions.
Before using this method you must have associated the receiver with a view. |
- (void)dealloc
| This method deallocates the parser. |
The following is a complete calling sequence of a dictionary parser and makes graphical representation of constructor in graph_view.
parser = [[VvidgetCodeDictionaryParser alloc] init];
/* graph_view is typically an outlet set in a nib file. */
[parser VC_associate_with_view:graph_view];
/* ... Load the constructor here ... */
[parser VC_update_using_dictionary_constructor:constructor];
The parser associates a Dictionary Constructor with a Vvidget Code View object and causes the association to synchronize using the VC_update_using_dictionary_constructor method. Consult the Dictionary Constructor and View sections for the associated features.
