Constructor & Destructor Documentation

◆ ZipDataStream() [1/2]

Ogre::ZipDataStream::ZipDataStream ( ZZIP_FILE zzipFile,
size_t  uncompressedSize 
)

Unnamed constructor.

◆ ZipDataStream() [2/2]

Ogre::ZipDataStream::ZipDataStream ( const String name,
ZZIP_FILE zzipFile,
size_t  uncompressedSize 
)

Constructor for creating named streams.

◆ ~ZipDataStream()

Ogre::ZipDataStream::~ZipDataStream ( )

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
trimAfterIf 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,
const char ,
int  ,
const char  
)
inlineinherited

◆ operator delete() [3/3]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete ( void ptr,
void  
)
inlineinherited

◆ operator delete[]() [1/2]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete[] ( void ptr)
inlineinherited

◆ operator delete[]() [2/2]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete[] ( void ptr,
const char ,
int  ,
const char  
)
inlineinherited

◆ operator new() [1/3]

template<class Alloc >
void * Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz)
inlineinherited

◆ operator new() [2/3]

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

operator new, with debug line info

◆ operator new() [3/3]

template<class Alloc >
void * Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz,
void ptr 
)
inlineinherited

placement operator new

◆ operator new[]() [1/2]

template<class Alloc >
void * Ogre::AllocatedObject< Alloc >::operator new[] ( size_t  sz)
inlineinherited

◆ operator new[]() [2/2]

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

array operator new, with debug line info

◆ operator>>()

template<typename T >
DataStream & Ogre::DataStream::operator>> ( T &  val)
inherited

◆ 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
bufReference to a buffer pointer
countNumber 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,
const String delim = "\n" 
)
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
bufReference to a buffer pointer
maxCountThe maximum length of data to be read, excluding the terminating character
delimThe delimiter to stop at
Returns
The number of bytes read, excluding the terminating character

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

◆ 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 ( const String delim = "\n")
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
delimThe 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
bufPointer to a buffer containing the bytes to write
countNumber of bytes to write
Returns
The number of bytes written

Reimplemented from Ogre::DataStream.
