Detailed Description

Common subclass of DataStream for handling data from C-style file handles.

Remarks:: Use of this class is generally discouraged; if you want to wrap file access in a DataStream, you should definitely be using the C++ friendly FileStreamDataStream. However, since there are quite a few applications and libraries still wedded to the old FILE handle access, this stream wrapper provides some backwards compatibility.

Constructor & Destructor Documentation

Ogre::FileHandleDataStream::FileHandleDataStream	(	FILE *	handle,
		uint16	accessMode = `READ`
	)

Create stream from a C file handle.

Ogre::FileHandleDataStream::FileHandleDataStream	(	const String &	name,
		FILE *	handle,
		uint16	accessMode = `READ`
	)

Create named stream from a C file handle.

Ogre::FileHandleDataStream::~FileHandleDataStream ( )

Member Function Documentation

void Ogre::FileHandleDataStream::close ( void ) [virtual]

Close the stream; this makes further operations invalid.

Implements Ogre::DataStream.

bool Ogre::FileHandleDataStream::eof ( void ) const [virtual]

Returns true if the stream has reached the end.

Implements Ogre::DataStream.

uint16 Ogre::DataStream::getAccessMode ( ) const [inherited]

Gets the access mode of the stream.

Definition at line 202 of file OgreDataStream.h.

virtual String Ogre::DataStream::getAsString ( void ) [virtual, inherited]

Returns a String containing the entire stream.

Remarks:: This is a convenience method for text streams only, allowing you to retrieve a String object containing all the data in the stream.

virtual String Ogre::DataStream::getLine ( bool trimAfter = true ) [virtual, inherited]

Returns a String containing the next line of data, optionally trimmed for whitespace.

Remarks:: This is a convenience method for text streams only, allowing you to retrieve a String object containing the next line of data. The data is read up to the next newline character and the result trimmed if required.

Note:: If you used this function, you must open the stream in binary mode, otherwise, it'll produce unexpected results.

Parameters:

trimAfter If true, the line is trimmed for whitespace (as in String.trim(true,true))

const String& Ogre::DataStream::getName ( void ) [inherited]

Returns the name of the stream, if it has one.

Definition at line 200 of file OgreDataStream.h.

virtual bool Ogre::DataStream::isReadable ( ) const [virtual, inherited]

Reports whether this stream is readable.

Definition at line 204 of file OgreDataStream.h.

virtual bool Ogre::DataStream::isWriteable ( ) const [virtual, inherited]

Reports whether this stream is writeable.

DataStream& Ogre::DataStream::operator>> ( T & val ) [inherited]

size_t Ogre::FileHandleDataStream::read	(	void *	buf,
		size_t	count
	)		`[virtual]`

Read the requisite number of bytes from the stream, stopping at the end of the file.

Parameters:

buf	Reference to a buffer pointer
count	Number of bytes to read

Returns:: The number of bytes read

Implements Ogre::DataStream.

virtual size_t Ogre::DataStream::readLine	(	char *	buf,
		size_t	maxCount,
		const String &	delim = `"\n"`
	)		`[virtual, inherited]`

Get a single line from the stream.

Remarks:: The delimiter character is not included in the data returned, and it is skipped over so the next read will occur after it. The buffer contents will include a terminating character.

Note:: If you used this function, you must open the stream in binary mode, otherwise, it'll produce unexpected results.

Parameters:

buf	Reference to a buffer pointer
maxCount	The maximum length of data to be read, excluding the terminating character
delim	The delimiter to stop at

Returns:: The number of bytes read, excluding the terminating character

Reimplemented in Ogre::FileStreamDataStream, and Ogre::MemoryDataStream.

void Ogre::FileHandleDataStream::seek ( size_t pos ) [virtual]

Repositions the read point to a specified byte.

Implements Ogre::DataStream.

size_t Ogre::DataStream::size ( void ) const [inherited]

Returns the total size of the data to be read from the stream, or 0 if this is indeterminate for this stream.

Definition at line 297 of file OgreDataStream.h.

void Ogre::FileHandleDataStream::skip ( long count ) [virtual]

Skip a defined number of bytes.

This can also be a negative value, in which case the file pointer rewinds a defined number of bytes.

Implements Ogre::DataStream.

virtual size_t Ogre::DataStream::skipLine ( const String & delim = "\n" ) [virtual, inherited]

Skip a single line from the stream.

Note:: If you used this function, you must open the stream in binary mode, otherwise, it'll produce unexpected results.

Parameters:

delim The delimiter(s) to stop at

Returns:: The number of bytes skipped

Reimplemented in Ogre::MemoryDataStream.

size_t Ogre::FileHandleDataStream::tell ( void ) const [virtual]

Returns the current byte offset from beginning.

Implements Ogre::DataStream.

size_t Ogre::FileHandleDataStream::write	(	const void *	buf,
		size_t	count
	)		`[virtual]`

Write the requisite number of bytes from the stream (only applicable to streams that are not read-only)

Parameters:

buf	Pointer to a buffer containing the bytes to write
count	Number of bytes to write

Returns:: The number of bytes written

Reimplemented from Ogre::DataStream.
