Method Summary | |
---|---|
String |
addAttributes(GUIAttributes attrs)
The addAttributes code does two things; it creates the lib.java code necessary for the attributes and it type checks for all attributes. |
String |
addChild(String childType,
String childId,
GUIAttributes attrs)
Check to make sure the childType is legal for the widget, then add it. |
Map<String,List<String>> |
getChildDefaults()
Specifies the child attributes for the widget. |
Map<String,List<String>> |
getDefaults()
Every attribute in our language has to have a default setting. |
Set<String> |
getImports()
getImports keeps a Set of import lines that are pertinent to the code generated in the other methods. |
String |
getLanguage()
Accessor method for the Widget language. |
List<String> |
getModifiers()
getModifiers returns a list of methods designed to modify various attributes of the widget type in question. |
List<String> |
getVariables()
Returns a chunk of code intended to declare variables which the backend code may need access to and therefore should be declared outside of the constructor code. |
String |
preamble()
Get the chunk of initialization code to be run first. |

- The widget type of the child.childId
- The identifier of the child.attrs
- The child's GUIAttributes map. Child attributes will be
read from this map.
BadChildWidgetException
- If the child is of an inappropriate
type. For instance, a menu can only have certain widgets (items,
submenus, etc.) as children.
BadAttributeException
- If one of the given attributes is
erroneous.public Set<String> getImports()
