This class class provides a default implementation ignoring warnings and recoverable errors and throwing a SAXParseException for fatal errors. If a CSS application needs to implement customized error handling, it must extend this class and then register an instance with the CSS parser using the parser's setErrorHandler method. The parser will then report all errors and warnings through this interface. The parser shall use this class instead of throwing an exception: it is up to the application whether to throw an exception for different types of errors and warnings. Note, however, that there is no requirement that the parser continue to provide useful information after a call to fatalError (in other words, a CSS driver class could catch an exception and report a fatalError). cCst|_dSN)rr_logselfr @/var/www/html/myenv/lib/python3.10/site-packages/cssutils/sac.py__init__szErrorHandler.__init__NcC|jj||dddSNT) neverraise)rerrorr exceptiontokenr r r rzErrorHandler.errorcCs|j||dSr)rfatalrr r r r"szErrorHandler.fatalcCrr)rwarnrr r r r%rzErrorHandler.warnr)__name__ __module__ __qualname____doc__r rrrr r r r r s   rc@speZdZdZddZdddZddZdd d Zdd d Zdd dZ dddZ dddZ dddZ dddZ dS)DocumentHandlera void endFontFace() Receive notification of the end of a font face statement. void endMedia(SACMediaList media) Receive notification of the end of a media statement. void endPage(java.lang.String name, java.lang.String pseudo_page) Receive notification of the end of a media statement. void importStyle(java.lang.String uri, SACMediaList media, java.lang.String defaultNamespaceURI) Receive notification of a import statement in the style sheet. void startFontFace() Receive notification of the beginning of a font face statement. void startMedia(SACMediaList media) Receive notification of the beginning of a media statement. void startPage(java.lang.String name, java.lang.String pseudo_page) Receive notification of the beginning of a page statement. cCsdd}||_dS)NcSstjd|dS)NzINFO %s )sysstderrwrite)msgr r r log=z%DocumentHandler.__init__..logr)r r!r r r r <s zDocumentHandler.__init__Nc C"|d|d|d|ddS)z"Receive notification of a comment.zcomment  at [, ]Nr#)r textlinecolr r r commentB"zDocumentHandler.commentcCs|d|dS)z7Receive notification of the beginning of a style sheet.zstartDocument encoding=%sNr#r encodingr r r startDocumentFszDocumentHandler.startDocumentcCs|ddS)z.Receive notification of the end of a document.zendDocument EOFNr#)r sourcer)r*r r r endDocumentKszDocumentHandler.endDocumentcCs|d|d|ddS)>Receive notification of a import statement in the style sheet.zimportStyle at [r&r'Nr#r urimedianamer)r*r r r importStyleOzDocumentHandler.importStylecCs|d|d|ddS)LReceive notification of an unknown rule t-rule not supported by this parser.znamespaceDeclaration at [r&r'Nr#r prefixr4r)r*r r r namespaceDeclarationTr8z$DocumentHandler.namespaceDeclarationcC|d|d|ddS)z:Receive notification of the beginning of a rule statement.zstartSelector at [r&r'Nr#r selectorsr)r*r r r startSelectorYr8zDocumentHandler.startSelectorcCr=)z4Receive notification of the end of a rule statement.zendSelector at [r&r'Nr#r>r r r endSelector^szDocumentHandler.endSelectorTODOFc Cs"|d|d|d|ddS)z&Receive notification of a declaration.z property r%r&r'Nr#r r6value importantr)r*r r r propertybs"zDocumentHandler.propertyc Cr$)r9zignorableAtRule r%r&r'Nr#)r atRuler)r*r r r ignorableAtRulegr,zDocumentHandler.ignorableAtRuleNNNNN)rBFNN)rrrrr r+r/r1r7r<r@rArFrHr r r r r)s       rcszeZdZdZfddZeddZfddZdfd d Zdfd d Z dfd d Z dddZ dfdd ZZ S) EchoHandlerz!Echos all input to property `out`cstg|_dSr)superr _outr  __class__r r r os  zEchoHandler.__init__cCs d|jS)N)joinrMr r r r ss zEchoHandler.cs,t|d|kr|jd|dSdS)Nutf-8z@charset "%s"; )rLr/rMappendr-rNr r r/us zEchoHandler.startDocumentNcsLt||||||jdt||rd|nd|rd|ndfdS)r2z@import %s%s%s; %s rPN)rLr7rMrTrstringr3rNr r r7zszEchoHandler.importStylecs<t|||||jd|rd|ndt|fdS)Nz@namespace %s%s; rUrP)rLr<rMrTrrVr:rNr r r<s z EchoHandler.namespaceDeclarationcs6t||||r|jd||jddS)Nr&z { )rLr@rMrTrQr>rNr r r@szEchoHandler.startSelectorcCs|jddS)Nz })rMrTr>r r r rAszEchoHandler.endSelectorFcs4t|||||jd|||rdnddS)Nz {}: {}{}; z !importantrP)rLrFrMrTformatrCrNr r rFszEchoHandler.propertyrIrJ)FNN) rrrrr rFoutr/r7r<r@rA __classcell__r r rNr rKls     rKc@s4eZdZdZd ddZd ddZddZd d ZdS) Parsera java.lang.String getParserVersion() Returns a string about which CSS language is supported by this parser. boolean parsePriority(InputSource source) Parse a CSS priority value (e.g. LexicalUnit parsePropertyValue(InputSource source) Parse a CSS property value. void parseRule(InputSource source) Parse a CSS rule.
