| typedef GVariant* Glib::VariantStringBase::CType |
| Glib::VariantStringBase::VariantStringBase | ( | ) |
Default constructor.
|
explicit |
GVariant constructor.
| castitem | The GVariant to wrap. |
| take_a_reference | Whether to take an extra reference of the GVariant or not (not taking one could destroy the GVariant with the wrapper). |
|
static |
Creates a D-Bus object path variant with the contents of string.
string must be a valid D-Bus object path. Use is_object_path() if unsure.
| output | A location in which to store the new object path variant instance. |
| object_path | A normal nul-terminated string. |
|
static |
Creates a D-Bus type signature variant with the contents of string.
string must be a valid D-Bus type signature. Use is_signature() if unsure.
| output | A location in which to store the new signature variant instance. |
| signature | A normal nul-terminated string. |
|
static |
Determines if a given string is a valid D-Bus object path.
You should ensure that a string is a valid D-Bus object path before passing it to g_variant_new_object_path().
A valid object path starts with '/' followed by zero or more sequences of characters separated by '/' characters. Each sequence must contain only the characters "[A-Z][a-z][0-9]_". No sequence (including the one following the final '/' character) may be empty.
| string | A normal C nul-terminated string. |
true if string is a D-Bus object path.
|
static |
Determines if a given string is a valid D-Bus type signature.
You should ensure that a string is a valid D-Bus type signature before passing it to g_variant_new_signature().
D-Bus type signatures consist of zero or more definite VariantType strings in sequence.
| string | A normal C nul-terminated string. |
true if string is a D-Bus type signature.
