## Detailed Description

makes an AND operator between two or more masks

Definition at line 272 of file mask.hpp.

## Constructor & Destructor Documentation

## et_mask() [1/3]

libdar::et_mask::et_mask | ( |  | ) |

inline

the constructor to be used by libdar external programs

Note
  at this stage the mask is not usable and will throw an exception until some mask are added to the AND thanks to the add_mask() method

Definition at line 281 of file mask.hpp.

Referenced by clone(), et_mask(), et_mask(), operator=(), and operator=().

## et_mask() [2/3]

libdar::et_mask::et_mask | ( | const et_mask & | m | ) |

inline

copy constructor

Definition at line 284 of file mask.hpp.

References et_mask().

## et_mask() [3/3]

libdar::et_mask::et_mask | ( | et_mask && | m | ) |

inline noexcept

move constructor

Definition at line 287 of file mask.hpp.

References et_mask().

## ~et_mask()

libdar::et_mask::~et_mask | ( |  | ) |

inline

destructor

Definition at line 296 of file mask.hpp.

## Member Function Documentation

## add_mask()

void libdar::et_mask::add_mask | ( | const mask & | toadd | ) |

add a mask to the operator

Parameters

  [in] | toadd | a mask to add to the AND operator

Note
  the mask given in argument has not to survive the et_mask to which it has been added a internal copy of the mask has been done.

## clear()

void libdar::et_mask::clear | ( |  | ) |

inline

clear the mask

remove all previously added masks

Note
  that after this call the mask is no more usable as the AND operator cannot be done on any mask

Definition at line 328 of file mask.hpp.

## clone()

mask * libdar::et_mask::clone | ( |  | ) | const

inline override virtual

inherited from the mask class

Implements libdar::mask.

Reimplemented in libdar::ou_mask.

Definition at line 312 of file mask.hpp.

References et_mask().

## dump()

std::string libdar::et_mask::dump | ( | const std::string & | prefix | ) | const

inline override virtual

dump in human readable form the nature of the mask

Parameters

  [in] | prefix | used for indentation withing the output string

Implements libdar::mask.

Reimplemented in libdar::ou_mask.

Definition at line 309 of file mask.hpp.

## get_added()

const mask * libdar::et_mask::get_added | ( | U_I | index | ) | const

inline

return a pointer by index to composing mask (index start at zero and should be strictly less than what size() returns)

Definition at line 321 of file mask.hpp.

## is_covered() [1/2]

bool libdar::et_mask::is_covered | ( | const path & | chemin | ) | const

inline override virtual

check whether the given path is covered by the mask

Parameters

  [in] | chemin | is the path to check

Returns
  true if the given path is covered by the mask

Note
  only libdar internally needs to call this method
  this is an optional method to the previous one, it can be overwritten

Reimplemented from libdar::mask.

Reimplemented in libdar::ou_mask.

Definition at line 308 of file mask.hpp.

## is_covered() [2/2]

bool libdar::et_mask::is_covered | ( | const std::string & | expression | ) | const

inline override virtual

inherited from the mask class

Implements libdar::mask.

Reimplemented in libdar::ou_mask.

Definition at line 307 of file mask.hpp.

## operator=()

et_mask & libdar::et_mask::operator= | ( | et_mask && | m | ) |

inline noexcept

move operator

Definition at line 293 of file mask.hpp.

References et_mask().

## size()

U_I libdar::et_mask::size | ( |  | ) | const

inline

the number of mask on which is done the AND operator

Returns
  the number of mask that has been added thanks to the add_mask() method

Note
  there is no mean to remove a given mask once it has been added (see the clear method)

Definition at line 318 of file mask.hpp.

## t_is_covered()

template<class T>

bool libdar::et_mask::t_is_covered | ( | const T & | expression | ) | const

inline private

Definition at line 340 of file mask.hpp.
