public static String[] parseNamespaceIdent(String attrName)
Parses a single namespace identifier. This simply splits the given attribute name when a namespace separator is encountered ('|').

Parameters: attrName the attribute name

Returns: the parsed attribute.

parseSelector

public SelectorList parseSelector(Map namespaces, String selector, ResourceManager resourceManager, ResourceKey baseURL)
Parses a single style value for the given key. Returns null, if the key denotes a compound definition, which has no internal representation.

Parameters: namespaces an optional map of known namespaces (prefix -> uri) selector the selector text that should be parsed. resourceManager an optional resource manager baseURL an optional base url

Returns: the parsed selector or null

parseStyleRule

public CSSDeclarationRule parseStyleRule(Map namespaces, String styleText, ResourceManager resourceManager, ResourceKey baseURL, CSSDeclarationRule baseRule)
Parses a style rule.

Parameters: namespaces an optional map of known namespaces (prefix -> uri) styleText the css text that should be parsed resourceManager an optional resource manager baseURL an optional base url baseRule an optional base-rule to which the result gets added.

public CSSStyleRule parseStyles(Map namespaces, StyleKey key, String value, ResourceManager resourceManager, ResourceKey baseURL)
Parses a style value. If the style value is a compound key, the corresonding style entries will be added to the style rule.

Parameters: namespaces an optional map of known namespaces (prefix -> uri) key the stylekey to which the value should be assigned. value the value text resourceManager an optional resource manager baseURL an optional base url

Returns: the CSS-Style-Rule that contains all values for the given text.

parseStyles

public CSSStyleRule parseStyles(Map namespaces, String name, String value, ResourceManager resourceManager, ResourceKey baseURL)
