Constructor Summary

RowLayout(Widget widget, WidgetDef parent)

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.
protected String	getAxisId()
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.

Constructor Detail

RowLayout

public RowLayout(Widget widget,
                 WidgetDef parent)

Method Detail

getAxisId

protected String getAxisId()

getLanguage

public final String getLanguage()

Description copied from class: WidgetDef

Accessor method for the Widget language.

Specified by:

getLanguage in class WidgetDef

Returns:

language

preamble

public String preamble()

Description copied from class: WidgetDef

Get the chunk of initialization code to be run first. Typically this code will declare a local variable for the widget.

Note that, by its nature, a preamble should only be called once; therefore the preamble is not inherited.

Specified by:

preamble in class WidgetDef

Returns:

Instatiation code.

getDefaults

public final Map<String,List<String>> getDefaults()

Description copied from class: WidgetDef

Every attribute in our language has to have a default setting. This returns all the defaults in a map of Strings to Lists of Strings.

Specified by:

getDefaults in class WidgetDef

Returns:

Map of attribute defaults

addAttributes

public final String addAttributes(GUIAttributes attrs)
                           throws BadAttributeException

Description copied from class: WidgetDef

The addAttributes code does two things; it creates the lib.java code necessary for the attributes and it type checks for all attributes. A BadAttributeException is thrown if the names or the values are erroneous. If an attribute is not found in the GUIAttributes, a BadAttributeNameException is thrown from GUIAttributes.

Specified by:

addAttributes in class WidgetDef

Parameters:

attrs - The attributes to set for the widget.

Returns:

The generated code to set the attributes.

Throws:

BadAttributeException

addChild

public final String addChild(String childType,
                             String childId,
                             GUIAttributes attrs)

Description copied from class: WidgetDef

Check to make sure the childType is legal for the widget, then add it.

Overrides:

addChild in class WidgetDef

Parameters:

childType - 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.

Returns:

The generated code to add the child to this widget.

getImports

public final Set<String> getImports()

Description copied from class: WidgetDef

getImports keeps a Set of import lines that are pertinent to the code generated in the other methods.

Specified by:

getImports in class WidgetDef

Returns:

Set of import strings.

getModifiers

public final List<String> getModifiers()

Description copied from class: WidgetDef

getModifiers returns a list of methods designed to modify various attributes of the widget type in question. When getModifiers is called, the accessors and mutators for all attributes are returned.

Specified by:

getModifiers in class WidgetDef

Returns:

List of mutators and accessors for the widget type.

getVariables

public final List<String> getVariables()

Description copied from class: WidgetDef

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.

Specified by:

getVariables in class WidgetDef

Returns:

Variable Declaration for the widget.
