bool ExtractorDocumentProcessor::canHandleData ( const QByteArray encodedData,
QStringView  fileName 
) const
QJSValue ExtractorDocumentProcessor::contentToScriptValue ( const ExtractorDocumentNode node,
QJSEngine engine 
) const

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 86 of file extractordocumentprocessor.cpp.

ExtractorDocumentNode ExtractorDocumentProcessor::createNodeFromContent ( const QVariant decodedData) const

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 29 of file extractordocumentprocessor.cpp.

void ExtractorDocumentProcessor::destroyNode ( ExtractorDocumentNode node) const

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 91 of file extractordocumentprocessor.cpp.

void ExtractorDocumentProcessor::expandNode ( ExtractorDocumentNode node,
const ExtractorEngine engine 
) const
bool ExtractorDocumentProcessor::matches ( const ExtractorFilter filter,
const ExtractorDocumentNode node 
) const

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 51 of file extractordocumentprocessor.cpp.

void ExtractorDocumentProcessor::postExtract ( ExtractorDocumentNode node) const

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::PkPassDocumentProcessor.

Definition at line 82 of file extractordocumentprocessor.cpp.

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

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::ExternalProcessor, KItinerary::HtmlDocumentProcessor, KItinerary::JsonLdDocumentProcessor, KItinerary::PkPassDocumentProcessor, KItinerary::Uic9183DocumentProcessor, KItinerary::IataBcbpDocumentProcessor, and KItinerary::VdvDocumentProcessor.

Definition at line 47 of file extractordocumentprocessor.cpp.

void ExtractorDocumentProcessor::reduceNode ( ExtractorDocumentNode node) const

Propagate results from child nodes up to node.

The default implementation just appends results.
