Detailed Description

Member Function Documentation

exists()

static bool Common::File::exists ( const Path &  filename )

static

Check if a given file exists in any of the current default paths, as defined by SearchMan.

Parameters

filename

The file to check for.

Returns

True if the file exists, false otherwise.

open() [1/4]

virtual bool Common::File::open ( const Path &  filename )

virtual

Try to open the file with the given file name, by searching SearchMan.

Note

Must not be called if this file is already open (i.e. if isOpen returns true).

Parameters

filename

Name of the file to open.

Returns

True if the file was opened successfully, false otherwise.

Reimplemented in Pink::BroFile, MM::Shared::Xeen::File, Pink::OrbFile, Ultima::Shared::File, Titanic::File, and Got::File.

open() [2/4]

virtual bool Common::File::open ( const Path &  filename, Archive &  archive  )

virtual

Try to open the file with the given file name from within the given archive.

Note

Must not be called if this file is already open (i.e. if isOpen returns true).

Parameters

filename	Name of the file to open.
archive	Archive in which to search for the file.

Returns

True if the file was opened successfully, false otherwise.

Reimplemented in MM::Shared::Xeen::File, and Ultima::Shared::File.

open() [3/4]

virtual bool Common::File::open ( const FSNode &  node )

virtual

Try to open the file corresponding to the given node. Will check whether the node actually refers to an existing file (and not a directory), and handle those cases gracefully.

Note

Must not be called if this file already is open (i.e. if isOpen returns true).

Parameters

node	The node to consider.

Returns

True if the file was opened successfully, false otherwise.

Reimplemented in MM::Shared::Xeen::File, and Ultima::Shared::File.

open() [4/4]

virtual bool Common::File::open ( SeekableReadStream *  stream, const String &  name  )

virtual

Try to 'open' the given stream. That is, wrap around it, and if the stream is a NULL pointer, gracefully treat this as if opening failed.

Note

Must not be called if this file already is open (i.e. if isOpen returns true).

Parameters

stream	Pointer to a SeekableReadStream, or 0.
name	String describing the 'file' corresponding to the stream.

Returns

True if the stream was non-zero, false otherwise.

close()

virtual void Common::File::close ( )

virtual

Close the file, if open.

Reimplemented in Ultima::Shared::File.

isOpen()

bool Common::File::isOpen

(

)

const

Check if the object opened a file successfully.

Returns

True if any file is opened, false otherwise.

getName()

const char* Common::File::getName ( ) const

inline

Return the file name of the opened file for debugging purposes.

Returns

The file name of the opened file.

err()

bool Common::File::err ( ) const

overridevirtual

Implement abstract Stream method.

Reimplemented from Common::Stream.

clearErr()

void Common::File::clearErr ( )

overridevirtual

Implement abstract Stream method.

Reimplemented from Common::Stream.

eos()

bool Common::File::eos ( ) const

overridevirtual

Implement abstract SeekableReadStream method.

Implements Common::ReadStream.

pos()

int64 Common::File::pos ( ) const

overridevirtual

Implement abstract SeekableReadStream method.

Implements Common::SeekableReadStream.

size()

int64 Common::File::size ( ) const

overridevirtual

Implement abstract SeekableReadStream method.

Implements Common::SeekableReadStream.

seek()

bool Common::File::seek ( int64  offs, int  whence = SEEK_SET  )

overridevirtual

Implement abstract SeekableReadStream method.

Implements Common::SeekableReadStream.

read()

uint32 Common::File::read ( void *  dataPtr, uint32  dataSize  )

overridevirtual

Implement abstract SeekableReadStream method.

Implements Common::ReadStream.

Reimplemented in MutationOfJB::EncryptedFile.

Member Data Documentation

_handle

SeekableReadStream* Common::File::_handle

protected

File handle to the actual file; 0 if no file is open.

_name

String Common::File::_name

protected

The name of this file, kept for debugging purposes.
