Detailed Description

An ISO9660 parser.

This class is a simple ISO9660 parser. It is not meant to be a full implementation, but rather a simple parser that can be used to find the files to be loaded.

Constructor & Destructor Documentation

ISO9660Parser()

psyqo::ISO9660Parser::ISO9660Parser ( CDRom *  cdrom )

inline

The ISO9660Parser constructor.

This constructor takes a CDRom device as a parameter. It will use that device to read the structure of the ISO9660 filesystem.

Parameters

cdrom

The CDRom device to use.

Member Function Documentation

getCDRom()

CDRom * psyqo::ISO9660Parser::getCDRom ( )

inline

Returns the CDRom object used by the parser.

Returns

The CDRom object.

getDirentry() [1/2]

GetDirentryAwaiter psyqo::ISO9660Parser::getDirentry ( eastl::string_view  path, DirEntry *  entry  )

inline

getDirentry() [2/2]

void psyqo::ISO9660Parser::getDirentry	(	eastl::string_view	path,
		DirEntry *	entry,
		eastl::function< void(bool success)>	callback
	)

Get the Direntry object for a given path.

This method looks up the directory entry for a given path. It will fail if the CDRom device fails reading the disk, or if the parser hasn't been initialized yet. If the directory entry is not found, the callback or task will still be successful, but the directory entry will be invalid.

Parameters

[in]	path	The path to look for.
[out]	entry	The DirEntry object to fill.

initialize() [1/2]

InitializeAwaiter psyqo::ISO9660Parser::initialize ( )

inline

initialize() [2/2]

void psyqo::ISO9660Parser::initialize

(

eastl::function< void(bool success)>

callback

)

Initializes the parser.

This method initializes the basic internal structures of the parser. It must be called before any other method. If the underlying CDRom device fails reading, or if the filesystem is not an ISO9660, the callback or task will fail. It can be called multiple times, and has to be called when the user changes the disc in the drive.

initialized()

bool psyqo::ISO9660Parser::initialized ( )

inline

Returns the state of the parser.

This method returns true if the parser was initialized successfully, and false otherwise.

Returns

The root directory entry.

scheduleGetDirentry()

psyqo::TaskQueue::Task psyqo::ISO9660Parser::scheduleGetDirentry	(	eastl::string_view	path,
		DirEntry *	entry
	)

scheduleInitialize()

psyqo::TaskQueue::Task psyqo::ISO9660Parser::scheduleInitialize

(

)

scheduleReadRequest()

psyqo::TaskQueue::Task psyqo::ISO9660Parser::scheduleReadRequest

(

ReadRequest *

request

)

Read a file asynchronously.

This method reads a file asynchronously. It will read the file from the given entry in the ReadRequest, and will read the number of sectors corresponding to the entry's size. The buffer is specified by the buffer field in the ReadRequest, and must be large enough to hold the whole file. This method is mainly a helper around the CDRom device's readSectors method.

Parameters

[in]

request

The request to fill.
