parseSelector

public org.w3c.css.sac.SelectorList parseSelector(java.util.Map namespaces,
                                                  java.lang.String selector,
                                                  org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,

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

parseStyleValue

public CSSValue parseStyleValue(java.util.Map namespaces,
                                StyleKey key,
                                java.lang.String value,
                                org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,
                                org.pentaho.reporting.libraries.resourceloader.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)

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 parsed value or null, if the value was not valid.

parseLexicalStyleValue

public org.w3c.css.sac.LexicalUnit parseLexicalStyleValue(java.lang.String value)

Parses an single lexical unit. This returns the un-interpreted tokenized value. The only use this method has is to parse performance critical tokens.

Parameters:

value - the value as string.

Returns:

the parsed value or null, if the string was unparseable.

parseStyles

public CSSStyleRule parseStyles(java.util.Map namespaces,
                                StyleKey key,

                                org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,
                                org.pentaho.reporting.libraries.resourceloader.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.

parseStyleRule

public CSSDeclarationRule parseStyleRule(java.util.Map namespaces,
                                         java.lang.String styleText,
                                         org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,
                                         org.pentaho.reporting.libraries.resourceloader.ResourceKey baseURL,
