Queries¶

Osid Query¶

class dlkit.osid.queries.OsidQuery¶

Bases: dlkit.osid.markers.Suppliable

The OsidQuery is used to assemble search queries.

An OsidQuery is available from an OsidQuerySession and defines methods to match objects. Once the desired parameters are set, the OsidQuery is given to the designated search method. The same OsidQuery returned from the session must be used in the search as the provider may utilize implementation-specific data wiithin the object.

If multiple data elements are set in this interface, the results matching all the given data (eg: AND) are returned.

Any match method inside an OsidQuery may be invoked multiple times. In the case of a match method, each invocation adds an element to an OR expression. Any of these terms may also be negated through the match flag.

OsidQuery { OsidQuery.matchDisplayName AND (OsidQuery.matchDescription OR OsidQuery.matchDescription)}

OsidObjects allow for the definition of an additonal records and the OsidQuery parallels this mechanism. An interface type of an OsidObject record must also define the corresponding OsidQuery record which is available through query interfaces. Multiple requests of these typed interfaces may return the same underlying object and thus it is only useful to request once.

An OsidQuery may be used to query for set or unset values using the “match any” methods. A field that has not bee explicitly assigned may default to a value. If multiple language translations exist and the query session is placed in a non-default locale, fields that have not been explicitly assigned in the non-default locale are considered unset even if the values from the default locale appear in the objects.

A string match type specifies the syntax of the string query, such as matching a word or including a wildcard or regular expression.

Returns:	a list containing the supported string match types
Return type:	`osid.type.TypeList`

Parameters:	keyword (`string`) – keyword to match string_match_type (`osid.type.Type`) – the string match type match (`boolean`) – `true` for a positive match, `false` for a negative match
Raise:	`InvalidArgument` – `keyword` is not of `string_match_type`

The OsidObjectQuery is used to assemble search queries.

An OsidObjectQuery is available from an OsidSession and defines methods to query for an OsidObject that includes setting a display name and a description. Once the desired parameters are set, the OsidQuery is given to the designated search method. The same OsidQuery returned from the session must be used in the search as the provider may utilize implementation-specific data wiithin the object.

If multiple data elements are set in this interface, the results matching all the given data (eg: AND) are returned.

Any match method inside an OsidObjectQuery may be invoked multiple times. In the case of a match method, each invocation adds an element to an OR expression. Any of these terms may also be negated through the match flag.

OsidObjectQuery { OsidQuery.matchDisplayName AND (OsidQuery.matchDescription OR OsidObjectQuery.matchDescription)}

OsidObjects allow for the definition of an additonal records and the OsidQuery parallels this mechanism. An interface type of an OsidObject record must also define the corresponding OsidQuery record which is available through query interfaces. Multiple requests of these typed interfaces may return the same underlying object and thus it is only useful to request once.

String searches are described using a string search Type that indicates the type of regular expression or wildcarding encoding. Compatibility with a strings search Type can be tested within this interface.

As with all aspects of OSIDs, nulls cannot be used. Separate tests are available for querying for unset values except for required fields.

An example to find all objects whose name starts with “Fred” or whose name starts with “Barney”, but the word “dinosaur” does not appear in the description and not the color is not purple. ColorQuery is a record of the object that defines a color.

ObjectObjectQuery query; query = session.getObjectQuery(); query.matchDisplayName(“Fred*”, wildcardStringMatchType, true); query.matchDisplayName(“Barney*”, wildcardStringMatchType, true); query.matchDescriptionMatch(“dinosaur”, wordStringMatchType, false);
