Member Function Documentation
Creates a new file attribute matcher, which matches attributes against a given string.
The attribute string should be formatted with specific keys separated from namespaces with a double colon. Several "namespace::key" strings may be concatenated with a single comma (e.g. "standard::type,standard::is-hidden"). The wildcard "*" may be used to match all keys and namespaces, or "namespace::*" will match all keys in a given namespace.
- Parameters:
-
| attributes | The attributes string. |
- Returns:
- a new FileAttributeMatcher.
| bool Gio::FileAttributeMatcher::enumerate_namespace |
( |
const std::string & |
ns | ) |
|
Checks if the matcher will match all of the keys in a given namespace.
This will always return true if a wildcard character is in use (e.g. if matcher was created with "standard::*" and ns is "standard", or if matcher was created using "*" and namespace is anything.)
TODO: this is awkwardly worded.
- Parameters:
-
| ns | A string containing a file attribute namespace. |
- Returns:
true if the matcher matches all of the entries in the given ns, false otherwise.
| std::string Gio::FileAttributeMatcher::enumerate_next |
( |
| ) |
|
Gets the next matched attribute from a FileAttributeMatcher.
- Returns:
- A string containing the next attribute or
0 if no more attribute exist.
| GFileAttributeMatcher* Gio::FileAttributeMatcher::gobj |
( |
| ) |
|
Provides access to the underlying C instance.
| const GFileAttributeMatcher* Gio::FileAttributeMatcher::gobj |
( |
| ) |
const |
Provides access to the underlying C instance.
| GFileAttributeMatcher* Gio::FileAttributeMatcher::gobj_copy |
( |
| ) |
const |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| bool Gio::FileAttributeMatcher::matches |
( |
const std::string & |
full_name | ) |
const |
Checks if an attribute will be matched by an attribute matcher.
If the matcher was created with the "*" matching string, this function will always return true.
- Parameters:
-
| attribute | A file attribute key. |
- Returns:
true if attribute matches matcher. false otherwise.
| bool Gio::FileAttributeMatcher::matches_only |
( |
const std::string & |
full_name | ) |
const |
Checks if a attribute matcher only matches a given attribute.
Always returns false if "*" was used when creating the matcher.
- Parameters:
-
| attribute | A file attribute key. |
- Returns:
true if the matcher only matches attribute. false otherwise.

const |
Increment the reference count for this object.
You should never need to do this manually - use the object via a RefPtr instead.
| void Gio::FileAttributeMatcher::unreference |
( |

const |
Decrement the reference count for this object.

- Parameters:
-
| object | The C instance. |
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
- Returns:
- A C++ instance that wraps this C instance.
