Member Function Documentation

close()

void Ogre::ZipDataStream::close ( void  )

virtual

Close the stream; this makes further operations invalid.

Implements Ogre::DataStream.

eof()

bool Ogre::ZipDataStream::eof ( void  ) const

virtual

Returns true if the stream has reached the end.

Implements Ogre::DataStream.

getAccessMode()

uint16 Ogre::DataStream::getAccessMode ( ) const

inlineinherited

Gets the access mode of the stream.

getAsString()

virtual String Ogre::DataStream::getAsString ( void  )

virtualinherited

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.

getLine()

virtual String Ogre::DataStream::getLine ( bool  trimAfter = true )

virtualinherited

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))

getName()

const String& Ogre::DataStream::getName ( void  )

inlineinherited

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

isReadable()

virtual bool Ogre::DataStream::isReadable ( ) const

inlinevirtualinherited

Reports whether this stream is readable.

isWriteable()

virtual bool Ogre::DataStream::isWriteable ( ) const

inlinevirtualinherited

Reports whether this stream is writeable.

operator delete() [1/3]

template<class Alloc >

void Ogre::AllocatedObject< Alloc >::operator delete ( void *  ptr )

inlineinherited

operator delete() [2/3]

template<class Alloc >

void Ogre::AllocatedObject< Alloc >::operator delete ( void *  ptr, void *    )

operator new() [1/3]

template<class Alloc >

void* Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz, const char *  file, int  line, const char *  func  )

read()

size_t Ogre::ZipDataStream::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.

readLine()

virtual size_t Ogre::DataStream::readLine ( char *  buf, size_t  maxCount  )

virtualinherited

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.

seek()

void Ogre::ZipDataStream::seek ( size_t  pos )

virtual

Repositions the read point to a specified byte.

Implements Ogre::DataStream.

size()

size_t Ogre::DataStream::size ( void  ) const

inlineinherited

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

skip()

void Ogre::ZipDataStream::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.

skipLine()

virtual size_t Ogre::DataStream::skipLine ( )

virtualinherited

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.

tell()

size_t Ogre::ZipDataStream::tell ( void  ) const

virtual

Repositions the read point to a specified byte.

Implements Ogre::DataStream.

write()

size_t Ogre::ZipDataStream::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.
