Additional Inherited Members | |
Protected Member Functions inherited from seqan3::file_validator_base | |
bool | case_insensitive_string_ends_with (std::string_view str, std::string_view suffix) const |
Helper function that checks if a string is a suffix of another string. Case insensitive. | |
std::string | valid_extensions_help_page_message () const |
Returns the information of valid file extensions. | |
void | validate_filename (std::filesystem::path const &path) const |
Validates the given filename path based on the specified extensions. | |
void | validate_readability (std::filesystem::path const &path) const |
Checks if the given path is readable. | |
void | validate_writeability (std::filesystem::path const &path) const |
Checks if the given path is writable. | |
Protected Attributes inherited from seqan3::file_validator_base | |
std::vector< std::string > | extensions {} |
Stores the extensions. | |
Related Symbols inherited from validator | |
using | option_value_type |
The type of value on which the validator is called on. | |
void | operator() (option_value_type const &cmp) const |
Validates the value 'cmp' and throws a seqan3::validation_error on failure. | |
A validator that checks if a given path is a valid output directory.
The class acts as a functor that throws a seqan3::validation_error exception whenever a given path (std::filesystem::path) is not writable. This can happen if either the parent path does not exists, or the path doesn't have the proper write permissions.

Returns a message that can be appended to the (positional) options help page info.
Implements validator.
|
inlineoverridevirtual |
Tests whether path is writable.
dir | The input value to check. |
seqan3::validation_error | if the validation process failed. Might be nested with std::filesystem::filesystem_error on unhandled OS API errors. |
Implements seqan3::file_validator_base.
