Package org.apache.flex.compiler.css Description

This package contains interfaces and classes representing various CSS concepts.

An ICSSDocument represents all the CSS code in a .css file or within a <Style> tag in MXML. It is the root of a tree of objects of type ICSSNode.

For example, CSS such as as

Button { color: red; font-size: 12 }

is represented by an ICSSRule which has one simple ICSSSelector named "Button" and two ICSSProperty objects named "color" and "font-size". Each ICSSProperty has an ICSSPropertyValue; in this case they represent the two values red and 12.

A rule can have a list of selectors, each of which can be a complex combination of simple selectors; they are stored in a linked-list-like data structure, where an ICSSCombinator in the link between between selectors.

Unlike AS and MXML source files, a CSS source file doesn't create a compilation unit in a project. There are three reasons for this:

• The dependency discovery loop for compilation units doesn't work for CSS.
• CSS syntax trees are not used by other sub-systems.
• The output of CSS is different than other compilation units' output. A CSS file does not contribute to a SWF tag of its own, and all of its content does not get generated into ABC code.
