bool | operator== (const entrepot &ref) const |
says whether two entrepot objects points to the same location | |

defines the root to use if set_location is given a relative path | |

this operator is called by the compiler if an exception is throw from the constructor of the allocated objects | |
void | operator delete (void *ptr) |
this is the usual delete operator, modified to handle allocated objects allocated on a memory pool or not | |

this is the usual delete[] operator, modified to handle allocated objects allocated on a memory pool or not | |

) | const |
defines the way to open a file and return a "class fichier_global" object as last argument upon success
[in] | dialog | for user interaction |
[in] | filename | is the full path+name of the file to open (read/create/write to) |
[in] | mode | defines which way to open the file (read-only, read-write or write-only) |
[in] | force_permission | whether to set the file permission to the value given in the permission argument |
[in] | permission | if force_permission is set, change the file permission to that value |
[in] | fail_if_exists | tells whether the underlying implementation have to fail throwing Erange("exists") if the file already exist when write access is required |
[in] | erase | tells whether the underlying implementation will empty an existing file before writing to it |
[in] | algo | defines the hash file to create, other value than hash_none are accepted only in writeonly mode with erase or fail_if_exist set |
