Detailed Description

chunk stream buffer.

Constructor & Destructor Documentation

Chunkstreambuf() [1/4]

Chunkstreambuf::Chunkstreambuf	(	std::streambuf *	streambuf,
		bool	own = false )

create the chunk stream buffer instance.

Parameters

streambuf	concrete stream buffer.
own	is the decorator owning inner stream buffer.

Chunkstreambuf() [2/4]

Chunkstreambuf::Chunkstreambuf	(	std::streambuf *	streambuf,
		std::streamsize	chunksize,
		bool	own = false )

create the chunk stream buffer instance.

Parameters

streambuf	concrete stream buffer.
chunksize	chunk size.
own	is the decorator owning inner stream buffer.

Member Function Documentation

operator=() [1/2]

Chunkstreambuf & Chunkstreambuf::operator=

(

Chunkstreambuf &&

other

)

Parameters

other

other object to assign.

Returns

current object.

overflow()

Chunkstreambuf::int_type Chunkstreambuf::overflow ( int_type c = traits_type::eof () )

overrideprotectedvirtual

writes characters to the associated output sequence from the put area.

Parameters

c	the character to store in the put area.

Returns

EOF on failure, some other value on success.

sync()

Chunkstreambuf::int_type Chunkstreambuf::sync ( )

overrideprotectedvirtual

synchronizes the buffers with the associated character sequence.

Returns

EOF on failure, some other value on success.

underflow()

overrideprotectedvirtual

reads characters from the associated input sequence to the get area.

Returns

the value of the character pointed to by the get pointer after the call on success, EOF otherwise.
