Detailed Description

Abstract base class for OSM file format readers.

Constructor & Destructor Documentation

AbstractReader()

AbstractReader::AbstractReader ( OSM::DataSet * dataSet )

explicitprotected

Definition at line 72 of file abstractreader.cpp.

Member Function Documentation

addNode()

void AbstractReader::addNode ( OSM::Node && node )

protected

Add read elements to the merge buffer if set, or the dataset otherwise.

Definition at line 121 of file abstractreader.cpp.

addRelation()

void AbstractReader::addRelation ( OSM::Relation && relation )

protected

Definition at line 131 of file abstractreader.cpp.

addWay()

void AbstractReader::addWay ( OSM::Way && way )

protected

Definition at line 126 of file abstractreader.cpp.

errorString()

QString AbstractReader::errorString

(

)

const

Error message in case parsing failed for some reason.

Definition at line 116 of file abstractreader.cpp.

read() [1/2]

void AbstractReader::read	(	const uint8_t *	data,
		std::size_t	len )

Read the given data.

Useful e.g. for working on memory-mapped data.

Definition at line 85 of file abstractreader.cpp.

read() [2/2]

void AbstractReader::read

(

QIODevice *

io

)

Read data from the given QIODevice.

Definition at line 93 of file abstractreader.cpp.

readFromData()

void AbstractReader::readFromData ( const uint8_t * data, std::size_t len )

protectedvirtual

Implement for actual parsing.

The default implementation convert into the respective other form, so implementing one is enough.

Definition at line 101 of file abstractreader.cpp.

readFromIODevice()

void AbstractReader::readFromIODevice ( QIODevice * io )

protectedvirtual

Definition at line 109 of file abstractreader.cpp.

setMergeBuffer()

void AbstractReader::setMergeBuffer

(

OSM::DataSetMergeBuffer *

buffer

)

Sets a merge buffer.

When set, the parser will insert all elements into that buffer rather than in the OSM::DataSet specified in the constructor. It is then your responsibility to properly integrate those.

Note

The OSM::DataSet is used for generating tag keys and for memory managing strings in this case as well. So the generated elements are tied to the OSM::DataSet in any case.
