## Detailed Description

implementation for entrepot to access to local filesystem

entrepot_local generates objects of class "fichier_local" inherited class of fichier_global

Definition at line 47 of file entrepot_local.hpp.

## Constructor & Destructor Documentation

## ◆ entrepot_local() [1/3]

libdar::entrepot_local::entrepot_local | ( | const std::string & | user,
|  | const std::string & | group,
|  | bool | x_furtive_mode )

constructor

Parameters

  [in] | user | defines the default user ownership of files created by the entrepot::open() method
  [in] | group | defines the default group ownership of files created by the entrepot::open() method
  [in] | x_furtive_mode | whether to ask the operating system to make furtive read access (no mtime/atime/ctime modification)

## Member Function Documentation

## ◆ clone()

virtual entrepot * libdar::entrepot_local::clone | ( |  | ) | const
| inlineoverridevirtual

done this way for homogeneity with open/inherited_open

generate a clone of "this"

Deprecated
  this method will disapear in the future it is only kept there to allow the APIv5 adaptation layer to work over APIv6

Implements libdar::entrepot.

Definition at line 74 of file entrepot_local.hpp.

## ◆ copy_from()

void libdar::entrepot_local::copy_from | ( | const entrepot_local & | ref | ) |
| inlineprivate

Definition at line 95 of file entrepot_local.hpp.

## ◆ create_dir()

virtual void libdar::entrepot_local::create_dir | ( | const std::string & | dirname,
|  | U_I | permission )
| overridevirtual

create a new directory in the current directory

Parameters

  [in] | dirname | is the name of the subdirectory to create (not its path!) It is created in as sub-directory of the directory given to set_location()
  [in] | permission | is the usual POSIX user/group/other permission bits to set to the directory to create

Note
  the operation fails if an entry of that name already exists
  the implementation should set the user and group ownership according to the argument provided to set_user_ownership() and set_group_ownership(), if this feature is supported in the underlying implementation

Implements libdar::entrepot.

## ◆ detruit()

void libdar::entrepot_local::detruit | ( |  | ) | const
| inlineprivate

Definition at line 97 of file entrepot_local.hpp.

## ◆ get_url()

virtual std::string libdar::entrepot_local::get_url | ( |  | ) | const
| inlineoverridevirtual

full path of current directory + anything necessary to provide URL formated information

Implements libdar::entrepot.

Definition at line 63 of file entrepot_local.hpp.

## ◆ inherited_open()

|  | const std::string & | filename,
|  | gf_mode | mode,
|  | bool | force_permission,

Definition at line 60 of file entrepot_local.hpp.

## ◆ read_dir_flush()

virtual void libdar::entrepot_local::read_dir_flush | ( |  | ) | const
| inlineoverrideprotectedvirtual

ends the read_dir_next, (no more entry available)

Implements libdar::entrepot.

Definition at line 88 of file entrepot_local.hpp.

## ◆ read_dir_next()

virtual bool libdar::entrepot_local::read_dir_next | ( | std::string & | filename | ) | const
| overridevirtual

read the next filename of the current directory

Parameters

  [out] | filename | name of the next entry in the directory, (valid only if this method returned true)

Returns
  false if no more filename could be fould

Note
  either use read_dir_reset() followed by read_dir_next() calls, or call read_dir_reset_dirinfo() followed by read_dir_next_dirinfo() calls

Implements libdar::entrepot.

## ◆ read_dir_next_dirinfo()

virtual bool libdar::entrepot_local::read_dir_next_dirinfo | ( | std::string & | filename,
|  | inode_type & | tp ) const
| overridevirtual

alternative to the method read_dir_next, should be implemented also

Parameters

  [out] | filename | name of the next entry in the directory, (valid only if this method returned true)
  [out] | tp | gives the nature of the entry

Note
  a call to read_dir_reset_dirinfo() should be done before the first call to this method
  either use read_dir_reset() followed by read_dir_next() calls, or call read_dir_reset_dirinfo() followed by read_dir_next_dirinfo() calls

Implements libdar::entrepot.

## ◆ read_dir_reset()

virtual void libdar::entrepot_local::read_dir_reset | ( |  | ) | const
| inlineoverridevirtual

Note
  dir_details does not matter for this implementation, both read_dir_next() can be used anytime.

Implements libdar::entrepot.

Definition at line 67 of file entrepot_local.hpp.

References read_dir_reset_dirinfo().

## ◆ read_dir_reset_dirinfo()

virtual void libdar::entrepot_local::read_dir_reset_dirinfo | ( |  | ) | const
| overridevirtual

routines to read existing files with dir information

to be used before calling read_dir_next_dirinfo().

Note
  after calling read_dir_reset_dirinfo() calling read_dir_next() gives undefined result, you first need to call read_dir_reset() or continue using read_dir_next_dirinfo()
