Represents a set of attributes that are stored with an item.

These schemas are used for interoperability between various services storing the same types of items.

Each schema has a name like org.gnome.keyring.NetworkPassword, and defines a set of attributes, and types (string, integer, boolean) for those attributes.

Attributes are stored as strings in the Secret Service, and the attribute types simply define standard ways to store integer and boolean values as strings. Attributes are represented in libsecret via a [structGLib.HashTable] with string keys and values. Even for values that defined as an integer or boolean in the schema, the attribute values in the [structGLib.HashTable] are strings. Boolean values are stored as the strings 'true' and 'false'. Integer values are stored in decimal, with a preceding negative sign for negative integers.

Schemas are handled entirely on the client side by this library. The name of the schema is automatically stored as an attribute on the item.

Normally when looking up passwords only those with matching schema names are returned. If the schema flags contain the SECRET_SCHEMA_DONT_MATCH_NAME flag, then lookups will not check that the schema name matches that on the item, only the schema's attributes are matched. This is useful when you are looking up items that are not stored by the libsecret library. Other libraries such as libgnome-keyring don't store the schema name.

Additional schemas can be defined via the %SecretSchema structure like this:

// in a header:

const SecretSchema * example_get_schema (void) G_GNUC_CONST;

#define EXAMPLE_SCHEMA example_get_schema ()


// in a .c file

const SecretSchema *
example_get_schema (void)
{
static const SecretSchema the_schema = {
"org.example.Password", SECRET_SCHEMA_NONE,
{
{ "number", SECRET_SCHEMA_ATTRIBUTE_INTEGER },
{ "string", SECRET_SCHEMA_ATTRIBUTE_STRING },
{ "even", SECRET_SCHEMA_ATTRIBUTE_BOOLEAN },
{ NULL, 0 },
}
};
return &the_schema;
}

Constructors

  • Using this function is not normally necessary from C code. This is useful for constructing #SecretSchema structures in bindings.

    A schema represents a set of attributes that are stored with an item. These schemas are used for interoperability between various services storing the same types of items.

    Each schema has an name like org.gnome.keyring.NetworkPassword, and defines a set of attributes names, and types (string, integer, boolean) for those attributes.

    Each key in the attributes table should be a attribute name strings, and the values in the table should be integers from the [enumSchemaAttributeType] enumeration, representing the attribute type for each attribute name.

    Normally when looking up passwords only those with matching schema names are returned. If the schema flags contain the %SECRET_SCHEMA_DONT_MATCH_NAME flag, then lookups will not check that the schema name matches that on the item, only the schema's attributes are matched. This is useful when you are looking up items that are not stored by the libsecret library. Other libraries such as libgnome-keyring don't store the schema name.

    Parameters

    • name: string

      the dotted name of the schema

    • flags: SchemaFlags

      the flags for the schema

    • attributeNamesAndTypes: HashTable<string | number | symbol, string | number | boolean>

      the attribute names and types of those attributes

    Returns Secret.Schema

Properties

attributes: SchemaAttribute[]

the attribute names and types of those attributes

field

flags for the schema

name: string

Methods

  • Adds a reference to the #SecretSchema.

    It is not normally necessary to call this function from C code, and is mainly present for the sake of bindings. If the schema was statically allocated, then this function will copy the schema.

    Returns Secret.Schema

  • unref(): void
  • Releases a reference to the #SecretSchema.

    If the last reference is released then the schema will be freed.

    It is not normally necessary to call this function from C code, and is mainly present for the sake of bindings. It is an error to call this for a schema that was statically allocated.

    Returns void

    • name: string

      the dotted name of the schema

      the flags for the schema

    • attributeNamesAndTypes: HashTable<string | number | symbol, string | number | boolean>

      the attribute names and types of those attributes

    Returns Secret.Schema
