Class Details¶

class GData.FreebaseQuery(**kwargs)¶

Bases:: GData.Query
Abstract:: No
Structure:: GData.FreebaseQueryClass

All the fields in the GData.FreebaseQuery structure are private and should never be accessed directly.

New in version 0.15.1.

classmethod new(mql)¶

Parameters:: mql (str) – a MQL query string
Returns:: a new GData.FreebaseQuery
Return type:: GData.FreebaseQuery

Creates a new GData.FreebaseQuery with the MQL query provided in mql. MQL is a JSON-based query language, analogous to SPARQL. To learn more about MQL, see the MQL overview and cookbook.

For detailed information on Freebase schemas, The “Schema” section on the main site allows for natural search and navigation through the multiple data properties and domains.

New in version 0.15.1.

Deprecated since version 0.17.7: Google Freebase has been permanently shut down.

classmethod new_from_variant(variant)¶

Parameters:: variant (GLib.Variant) – a variant containing the MQL query structure
Returns:: a new GData.FreebaseQuery
Return type:: GData.FreebaseQuery

Creates a new GData.FreebaseQuery with the MQL query provided in a serialized form as variant of type “a{smv}” containing the JSON data tree of a MQL query. One convenient way to build the variant is using Json.gvariant_serialize() from a Json.Node. For more information about MQL, see GData.FreebaseQuery.new().

GData.FreebaseQuery takes ownership on variant, if it has a floating reference, it will be sunk. Otherwise an extra reference will be added.

New in version 0.15.1.

Deprecated since version 0.17.7: Google Freebase has been permanently shut down.

Property Details¶

GData.FreebaseQuery.props.variant¶

Name:: variant
Type:: GLib.Variant
Default Value:: None
Flags:: DEPRECATED, READABLE, WRITABLE, CONSTRUCT_ONLY

Variant containing the MQL query. The variant is a very generic container of type “a{smv}”, containing (possibly nested) Freebase schema types and values.

New in version 0.15.1.

Deprecated since version 0.17.7: Google Freebase has been permanently shut down.
