Detailed Description

A node in the extracted document object tree.

Essentially this models a tree of variants representing the input document, Each node being associated with and managed by the KItinerary::ExtractorDocumentProcessor for its corresponding type. Each nodes also carries the result of data extraction on itself and/or its children. This is meant for consumption in both C++ and JS code.

Property Documentation

childNodes

const std::vector< ExtractorDocumentNode > & ExtractorDocumentNode::childNodes

read

Child nodes, for QJSEngine access.

Definition at line 57 of file extractordocumentnode.h.

content

QVariant ExtractorDocumentNode::content

read

The decoded content of this node.

The exact type in here depends on the MIME type, adapted for QJSEngine consumption.

Definition at line 64 of file extractordocumentnode.h.

contextDateTime

QDateTime ExtractorDocumentNode::contextDateTime

read

The best known context date/time at this point in the document tree.

If not set on this node, the context date/time of the parent node is returned.

Definition at line 68 of file extractordocumentnode.h.

location

QVariant ExtractorDocumentNode::location

read

Information about the location of this node in relation to one of its ancestors.

The exact meaning of this depends on the type of the node, one example would be a page number an image is found on in a PDF document.

Definition at line 76 of file extractordocumentnode.h.

mimeType

QString ExtractorDocumentNode::mimeType

read

The MIME type of this node.

Definition at line 60 of file extractordocumentnode.h.

parent

ExtractorDocumentNode ExtractorDocumentNode::parent

read

The parent node, or a null node if this is the root node.

Definition at line 55 of file extractordocumentnode.h.

result

ExtractorResult ExtractorDocumentNode::result

read

Result access for QJSEngine.

Definition at line 70 of file extractordocumentnode.h.

Constructor & Destructor Documentation

content() [1/2]

QVariant KItinerary::ExtractorDocumentNode::content

(

)

const

Returns the decoded content of this node.

The content of the QVariant depends on the MIME type.

content() [2/2]

Definition at line 124 of file extractordocumentnode.h.

contextDateTime()

QDateTime KItinerary::ExtractorDocumentNode::contextDateTime

(

)

const

The best known context date/time at this point in the document tree.

findChildNodes()

QVariantList ExtractorDocumentNode::findChildNodes

isA()

template<typename T >

bool KItinerary::ExtractorDocumentNode::isA ( ) const

inline

Checks if the content of this node is of type T.

Definition at line 116 of file extractordocumentnode.h.

isNull()

bool KItinerary::ExtractorDocumentNode::isNull

(

)

const
