Constructor & Destructor Documentation

proland::FileWriter::FileWriter	(	const string &	file,
		bool	binary = true
	)

Creates a new FileWriter.

Parameters:

	file	the path/name of the file to write into.
	binary	If true, will write in binary mode. Otherwise, in ASCII.

proland::FileWriter::~FileWriter

Member Function Documentation

void proland::FileWriter::magicNumber

(

int

i

)

[inline]

Writes the magic Number into the file.

Magic Number determines if the file is indexed or not.

Parameters:

i

the magic number. If 0 -> basic saving. If 1, indexed saving.

void proland::FileWriter::seekp	(	streamoff	off,
		ios_base::seekdir	dir
	)

Sets the position of the put pointer.

Parameters:

	off	integral value of type streamoff representing the offset to be applied relative to an absolute position specified in the dir parameter.
	dir	seeking direction. It is an object of type ios_base::seekdir that specifies an absolute position from where the offset parameter off is applied. It can take any of the following member constant values: ios_base::beg | ios_base::cur | ios_base::end.

streampos proland::FileWriter::tellp

(

)

Returns the position of the put pointer.

void proland::FileWriter::width

(

streamsize

wide

)

Sets a new field width for the output stream.

template<typename T >

void proland::FileWriter::write

(

T

t

)

[inline]

Write method.

Allows to write all sorts of data in the file.

Parameters:

t

the data to write.
