Methods

Modifier and Type	Method and Description
int	getArity() Get the node's child count.
ICSSCombinator	getCombinator() Get the combinator of this selector if it exists.
static com.google.common.collect.ImmutableList<ICSSSelector>	getCombinedSelectorList(ICSSSelector selector) Convert the selectors chained by combinators into a list of simple selectors ordering from ancestors to descendants.
com.google.common.collect.ImmutableList<ICSSSelectorCondition>	getConditions() Get selector conditions.
String	getCSSSyntax() This API is explicitly added so that no CSS compilation logic will depend on toString() value of an ICSSNode.
String	getElementName() Get the element name.
String	getNamespacePrefix() Get the namespace prefix.
ICSSNode	getNthChild(int index) Get the node's nth child.
CSSModelTreeType	getOperator() Get the node's type.

Field Detail

children

protected final List<ICSSNode> children

A list of children nodes. The sub-classes can add nodes to this list in their constructors.

Constructor Detail

CSSSelector

protected CSSSelector(CSSCombinator combinator,
           String elementName,
           String namespacePrefix,
           List<CSSSelectorCondition> conditions,
           org.antlr.runtime.tree.CommonTree tree,
           org.antlr.runtime.TokenStream tokenStream)

Method Detail

getElementName

public String getElementName()

Description copied from interface: ICSSSelector

Get the element name. For example, Label is the element name for "s|Label.noBorder".

Specified by:

getElementName in interface ICSSSelector

Returns:

Element name or null.

getNamespacePrefix

public String getNamespacePrefix()

Description copied from interface: ICSSSelector

Get the namespace prefix. For example, mx is the namespace prefix for "mx|Button".

Specified by:

getNamespacePrefix in interface ICSSSelector

Returns:

Namespace prefix or null.

getConditions

public com.google.common.collect.ImmutableList<ICSSSelectorCondition> getConditions()

Description copied from interface: ICSSSelector

Get selector conditions.

Example: selector conditions.

 s|Button.rounded#main:up
 

In this selector, the conditions are ".rounded", "#main" and ":up".

Specified by:

getConditions in interface ICSSSelector

Returns:

A list of conditions.

toString

public String toString()

Description copied from class: SourceLocation

Displays line, column, start, end, and sourcepath in a format such as

 "17:5 160-188 C:\test.as"
 

Overrides:

toString in class SourceLocation

getCSSSyntax

public String getCSSSyntax()

Description copied from interface: ICSSSelector

This API is explicitly added so that no CSS compilation logic will depend on toString() value of an ICSSNode.

Specified by:

getCSSSyntax in interface ICSSSelector

Returns:

The CSS text from which this selector is generated.

getCombinator

public ICSSCombinator getCombinator()

Description copied from interface: ICSSSelector

Get the combinator of this selector if it exists. A combinator is the selector on the left-hand side of the current selector.

Specified by:

getCombinator in interface ICSSSelector

Returns:

A combinator or null;

getCombinedSelectorList

public static com.google.common.collect.ImmutableList<ICSSSelector> getCombinedSelectorList(ICSSSelector selector)

Convert the selectors chained by combinators into a list of simple selectors ordering from ancestors to descendants.

For example: s|HBox s|VBox s|Label
will be converted to:
List { HBox, VBox, Label }

Parameters:

selector - The subject selector in a descendant selector chain.

Returns:

A list of selectors.

isAdvanced

public boolean isAdvanced()

This implementation is based on mx.styles::CSSStyleDeclaration.isAdvanced() in Flex SDK 4.5.2.

Specified by:

isAdvanced in interface ICSSSelector

Returns:

True if the selector has advanced syntax.

toStringTree

public String toStringTree()

Recursively print out the text representation of the tree.

Specified by:

toStringTree in interface ICSSNode

Returns:

Tree structure in text.

getArity

public int getArity()

Description copied from interface: ICSSNode

Get the node's child count. This method will be used by JBurg's DefaultAdapter.

Specified by:

getArity in interface ICSSNode

Returns:

Child count.

getNthChild

public ICSSNode getNthChild(int index)

Description copied from interface: ICSSNode

Get the node's nth child. This method will be used by JBurg's DefaultAdapter.

Specified by:

getNthChild in interface ICSSNode

Parameters:

index - Child index.

Returns:

The nth child node.

getOperator

public CSSModelTreeType getOperator()

Description copied from interface: ICSSNode

Get the node's type. This method will be used by JBurg's DefaultAdapter.

Specified by:

getOperator in interface ICSSNode

Returns:

Node type.
