Member Function Documentation

◆ beginEntryList()

IteratorUniquePtr AndroidAbstractFileEngine::beginEntryList	(	const QString &	path,
		QDir::Filters	filters,
		const QStringList &	filterNames )

inlineoverridevirtual

Returns a QAbstractFileEngine::IteratorUniquePtr, that can be used to iterate over the entries in path, using filters for entry filtering and filterNames for name filtering.

This function is called by QDirListing to initiate directory iteration.

Reimplemented from QAbstractFileEngine.

Definition at line 355 of file qandroidassetsfileenginehandler.cpp.

References filters, and AssetItem::type.

◆ caseSensitive()

bool AndroidAbstractFileEngine::caseSensitive ( ) const

inlineoverridevirtual

Should return true if the underlying file system is case-sensitive; otherwise return false.

Reimplemented from QAbstractFileEngine.

Definition at line 266 of file qandroidassetsfileenginehandler.cpp.

◆ close()

bool AndroidAbstractFileEngine::close ( )

inlineoverridevirtual

Closes the file, returning true if successful; otherwise returns false.

The default implementation always returns false.

Reimplemented from QAbstractFileEngine.

Referenced by ~AndroidAbstractFileEngine(), open(), and setFileName().

Here is the caller graph for this function:

◆ fileFlags()

FileFlags AndroidAbstractFileEngine::fileFlags ( FileFlags type = FileInfoAll ) const

inlineoverridevirtual

This function should return the set of OR'd flags that are true for the file engine's file, and that are in the type's OR'd members.

In your reimplementation you can use the type argument as an optimization hint and only return the OR'd set of members that are true and that match those in type; in other words you can ignore any members not mentioned in type, thus avoiding some potentially expensive lookups or system calls.

◆ fileName()

QString AndroidAbstractFileEngine::fileName ( FileName file = DefaultName ) const

inlineoverridevirtual

Return the file engine's current file name in the format specified by file.

If you don't handle some FileName possibilities, return the file name set in setFileName() when an unhandled format is requested.

Here is the call graph for this function:

◆ open()

bool AndroidAbstractFileEngine::open	(	QIODevice::OpenMode	openMode,
		std::optional< QFile::Permissions >	permissions )

inlineoverridevirtual

Opens the file in the specified mode.

Returns true if the file was successfully opened; otherwise returns false.

The mode is an OR combination of QIODevice::OpenMode and QIODevice::HandlingMode values.

If the file is created as a result of this call, its permissions are set according to permissision. Null value means an implementation- specific default.
