Detailed Description

MetaInfoJob is a KIO Job to retrieve meta information from files.

KIO Job to retrieve meta information from files.

Deprecated:: use Nepomuk or Strigi Note: this job doesn't even work as before, KFileItem::setMetaInfo doesn't exist anymore.

Definition at line 40 of file metainfojob.h.

Constructor & Destructor Documentation

◆ MetaInfoJob()

MetaInfoJob::MetaInfoJob	(	const KFileItemList &	items,
		KFileMetaInfo::WhatFlags	w = `KFileMetaInfo::Everything`,
		int	iocost = `3`,
		int	cpucost = `6`,
		const QStringList &	requiredfields = `QStringList()`,
		const QStringList &	requestedfields = `QStringList()`
	)

explicit

Creates a new MetaInfoJob.

Parameters

items	A list of KFileItems to get the metainfo for
w	Flags which serve as a preset which can be customized with other parameters.
iocost	The allowed cost in terms of io to retrieve the metainfo. The approximate maximum number of bytes to be read is 10^iocost. Negative values mean that there is no limit on the cost. 0 means that no fields other than the required fields will be retrieved. The default value of 3 means about 1024 bytes per file may be read. This is merely a suggestion and not a hard limit.
cpucost	The allowed cost in terms of cpu to determine the information in the fields. The number mean the amount of instructions allowed is 10^cpucost and is a suggestion only. The default value of 6 means that about a million instructions (10^6) are allowed. This is useful for expensive fields like md5 or thumbnails.
requiredfields	The names of fields or groups of fields that should be retrieved regardless of cost.
requestedfields	The names of fields or groups of fields that should be retrieved first.

Member Function Documentation

◆ failed

void KIO::MetaInfoJob::failed ( const KFileItem & item )

signal

Emitted when metainfo for item could not be extracted, either because a plugin for its MIME type does not exist, or because something went wrong.

Parameters

item	the KFileItem of the file that failed

◆ gotMetaInfo

void KIO::MetaInfoJob::gotMetaInfo ( const KFileItem & item )

signal

Emitted when the meta info for item has been successfully retrieved.

Parameters

item	the KFileItem describing the fetched item

◆ removeItem()

void MetaInfoJob::removeItem ( const KFileItem & item )

Removes an item from metainfo extraction.

Parameters

item	the item that should be removed from the queue
