Detailed Description

makes an AND operator between two or more masks

Definition at line 216 of file mask.hpp.

Constructor & Destructor Documentation

et_mask()

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 225 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 259 of file mask.hpp.

References libdar::dar_gettext().

is_covered()

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

inlinevirtual

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 243 of file mask.hpp.

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)
