Constructor Detail

CSSRule

public CSSRule(List<CSSMediaQueryCondition> mediaQueries,
       List<CSSSelector> selectorGroup,
       List<CSSProperty> properties,
       org.antlr.runtime.tree.CommonTree tree,
       org.antlr.runtime.TokenStream tokenStream)

Method Detail

getMediaQueryConditions

public com.google.common.collect.ImmutableList<ICSSMediaQueryCondition> getMediaQueryConditions()

Description copied from interface: ICSSRule

Get a list of media query conditions associated with this CSS rule.

Specified by:

getMediaQueryConditions in interface ICSSRule

Returns:

A list of ICSSMediaQueryCondition objects; Null if the rule is not enclosed in a media query.

getSelectorGroup

public com.google.common.collect.ImmutableList<ICSSSelector> getSelectorGroup()

Description copied from interface: ICSSRule

Get all the subjects in the selector group in their declared order.

A CSS rule can have one or many selectors separated by comma(s). Each selector has a subject.

The element of the right most simple selector in an ICSSSelector is the subject of the current selector object.

Example: selector subject.
Subject for "s|HBox s|Button.round s|Label.dark" is "Label".
Subject for "s|Panel .noskin" is "*". (".noskin" is the implicit form of "*.noskin").

The subject selector is the root of the combination of simple selectors in this "chain".

Example: selector combination.
A > B C ~ D E
"E" is the subject. Its linked to "D" as descendant; "D" is linked to "C" as general sibling; "B" is the child of "A".

Starting from the subject, you can walk up the chain right to left.

Example: CSS rule with selector group.

 s|HBox .rounded s|Label.big,
 s|VBox .rounded s|Label.small { fontWeight:bold; }
 

The return value for the above rule would be list [s|Label, s|Label].

Specified by:

getSelectorGroup in interface ICSSRule

Returns:

All the subjects in the selector group in their declared order.

getProperties

public com.google.common.collect.ImmutableList<ICSSProperty> getProperties()
