Detailed Description

Provides metadata extracted from files.

The reading of the metadata is done asynchronously in a process. This assures that the caller won't get blocked and also prevents that the caller crashes in case if a metadata-analyzer plugin is instable.

Member Function Documentation

void KFileMetaDataReader::finished ( )

signal

Is emitted if the reading of the metadata inside a custom process has been finished.

The method metaData() can be used afterwards to access the metadata.

QHash< KUrl, Nepomuk::Variant > KFileMetaDataReader::metaData

(

)

const

Returns

The read metadata of the given files. The method provides valid values after the signal finished() has been emitted. If it is invoked before an empty hash-table will be returned.

bool KFileMetaDataReader::readContextData

const

Definition at line 126 of file kfilemetadatareader.cpp.

void KFileMetaDataReader::setReadContextData

(

bool

read

)

If read is set to true also metadata that is persisted outside the files itself (like e.g.

rating, comments or tags) are read. Per default the reading of context data is enabled. Pass false if only the metadata persisted inside the file should be read.

Definition at line 121 of file kfilemetadatareader.cpp.

void KFileMetaDataReader::start

(

)

Starts the reading of the metadata inside a custom process.

The signal finished() will get emitted if the reading has been finished. Use metaData() to access the read metadata.
