Constructor & Destructor Documentation

libdar::tronc::tronc	(	generic_file *	f,
		const infinint &	offset,
		const infinint &	size,
		bool	own_f = false
	)

constructor

Parameters:

f	is the file to take the segment from
offset	is the position of the beginning of the segment
size	is the size of the segment
own_f	is true if this object has to owns and may destroy the 'f' object at tronc's destruction time

libdar::tronc::tronc	(	generic_file *	f,
		const infinint &	offset,
		bool	own_f = false
	)

other constructor, the end of the segment is the end of the underlying generic_file only data before offset is inaccessible

Member Function Documentation

void libdar::tronc::inherited_sync_write

(

)

[inline, protected, virtual]

write down any pending data

Note:

this method is called after read/write mode checking from sync_write() public method;

Implements libdar::generic_file.

Definition at line 84 of file tronc.hpp.

References libdar::generic_file::sync_write().

void libdar::tronc::inherited_terminate

(

)

[inline, protected, virtual]

destructor-like call, except that it is allowed to throw exceptions

Note:

this method must never be called directly but using terminate() instead, generic_file class manages it to never be called more than once

Implements libdar::generic_file.

Definition at line 85 of file tronc.hpp.

References libdar::generic_file::terminate().
