Member Function Documentation

canHandleData()

bool ExtractorDocumentProcessor::canHandleData ( const QByteArray &  encodedData, QStringView  fileName  ) const

virtual

Fast check whether the given encoded data can possibly be processed by this instance.

The default implementation returns false, relying on QMimeDatabase for detection.

Reimplemented in KItinerary::HarDocumentProcessor, KItinerary::SsbDocumentProcessor, KItinerary::PdfDocumentProcessor, KItinerary::ExternalProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::JsonLdDocumentProcessor, KItinerary::Uic9183DocumentProcessor, KItinerary::ElbDocumentProcessor, KItinerary::IataBcbpDocumentProcessor, KItinerary::IcalCalendarProcessor, KItinerary::MimeDocumentProcessor, KItinerary::PkPassDocumentProcessor, KItinerary::PListDocumentProcessor, KItinerary::TextDocumentProcessor, and KItinerary::VdvDocumentProcessor.

Definition at line 20 of file extractordocumentprocessor.cpp.

contentToScriptValue()

QJSValue ExtractorDocumentProcessor::contentToScriptValue ( const ExtractorDocumentNode &  node, QJSEngine *  engine  ) const

virtual

Create a QJSValue for the node content.

The default implementation is sufficient if the content is a QObject pointer, QGadget value, or any built-in type.

Reimplemented in KItinerary::IcalEventProcessor, KItinerary::PdfDocumentProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::PkPassDocumentProcessor, and KItinerary::BinaryDocumentProcessor.

Definition at line 107 of file extractordocumentprocessor.cpp.

createNodeFromContent()

ExtractorDocumentNode ExtractorDocumentProcessor::createNodeFromContent ( const QVariant &  decodedData ) const

virtual

Create a document node from an already decoded data type.

The default implementation just sets decodedData on the resulting node.

Reimplemented in KItinerary::PdfDocumentProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::MimeDocumentProcessor, and KItinerary::PkPassDocumentProcessor.

Definition at line 30 of file extractordocumentprocessor.cpp.

createNodeFromData()

ExtractorDocumentNode ExtractorDocumentProcessor::createNodeFromData ( const QByteArray &  encodedData ) const

virtual

Create a document node from raw data.

The default implementation produces in invalid node.

Reimplemented in KItinerary::HarDocumentProcessor, KItinerary::SsbDocumentProcessor, KItinerary::PdfDocumentProcessor, KItinerary::ExternalProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::JsonLdDocumentProcessor, KItinerary::Uic9183DocumentProcessor, KItinerary::ElbDocumentProcessor, KItinerary::IataBcbpDocumentProcessor, KItinerary::IcalCalendarProcessor, KItinerary::MimeDocumentProcessor, KItinerary::PkPassDocumentProcessor, KItinerary::PListDocumentProcessor, KItinerary::TextDocumentProcessor, KItinerary::VdvDocumentProcessor, KItinerary::BinaryDocumentProcessor, and KItinerary::ImageDocumentProcessor.

Definition at line 25 of file extractordocumentprocessor.cpp.

destroyNode()

void ExtractorDocumentProcessor::destroyNode ( ExtractorDocumentNode &  node ) const

virtual

Destroys type-specific data in node.

The default implementation does nothing.

Reimplemented in KItinerary::PdfDocumentProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::PkPassDocumentProcessor, and KItinerary::MimeDocumentProcessor.

Definition at line 112 of file extractordocumentprocessor.cpp.

expandNode()

void ExtractorDocumentProcessor::expandNode ( ExtractorDocumentNode &  node, const ExtractorEngine *  engine  ) const

virtual

Create child nodes for node, as far as that's necessary for this document type.

Reimplemented in KItinerary::HarDocumentProcessor, KItinerary::IcalEventProcessor, KItinerary::PdfDocumentProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::MimeDocumentProcessor, KItinerary::PkPassDocumentProcessor, KItinerary::Uic9183DocumentProcessor, KItinerary::IcalCalendarProcessor, KItinerary::PListDocumentProcessor, KItinerary::ImageDocumentProcessor, and KItinerary::HttpResponseProcessor.

Definition at line 37 of file extractordocumentprocessor.cpp.

matches()

bool ExtractorDocumentProcessor::matches ( const ExtractorFilter &  filter, const ExtractorDocumentNode &  node  ) const

virtual

Checks whether the given filter matches node.

The default implementation can handle QObject and Q_GADGET types via Qt's property system.

Reimplemented in KItinerary::IcalEventProcessor, KItinerary::MimeDocumentProcessor, KItinerary::IataBcbpDocumentProcessor, KItinerary::TextDocumentProcessor, and KItinerary::BinaryDocumentProcessor.

Definition at line 55 of file extractordocumentprocessor.cpp.

postExtract()

void ExtractorDocumentProcessor::postExtract ( ExtractorDocumentNode &  node, const ExtractorEngine *  engine  ) const

virtual

Called after extractors have been applied to node.

This can be used for applying document type specific data to the extracted result. The default implementation does nothing.

Reimplemented in KItinerary::IcalEventProcessor, KItinerary::PdfDocumentProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::PkPassDocumentProcessor, and KItinerary::TextDocumentProcessor.

Definition at line 103 of file extractordocumentprocessor.cpp.

preExtract()

void ExtractorDocumentProcessor::preExtract ( ExtractorDocumentNode &  node, const ExtractorEngine *  engine  ) const

virtual

Called before extractors are applied to node.

This can be used for performing document type specific extraction steps. The default implementation does nothing.

Reimplemented in KItinerary::IcalEventProcessor, KItinerary::SsbDocumentProcessor, KItinerary::ExternalProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::JsonLdDocumentProcessor, KItinerary::PkPassDocumentProcessor, KItinerary::Uic9183DocumentProcessor, KItinerary::IataBcbpDocumentProcessor, and KItinerary::VdvDocumentProcessor.

Definition at line 51 of file extractordocumentprocessor.cpp.

reduceNode()

void ExtractorDocumentProcessor::reduceNode ( ExtractorDocumentNode &  node ) const

virtual

Propagate results from child nodes up to node.

The default implementation just appends results.
