Operator Classes¶

The operclass module defines two classes: class OperatorClass derived from DbSchemaObject and class OperatorClassDict derived from DbObjectDict.

Operator Class¶

OperatorClass is derived from DbSchemaObject and represents a Postgres operator class.

class pyrseas.dbobject.operclass.OperatorClass(name, schema, index_method, description, owner, family, type, default=None, storage=None, oid=None)¶: An operator class

OperatorClass.extern_key()¶

Return the key to be used in external maps for this operator

Returns:	string

OperatorClass.identifier()¶

Return a full identifier for an operator class

Returns:	string

OperatorClass.to_map(db, no_owner)¶

Convert operator class to a YAML-suitable format

Returns:	dictionary

OperatorClass.create(dbversion=None)¶

Return SQL statements to CREATE the operator class

Returns:	SQL statements

Operator Class Dictionary¶

OperatorClassDict is derived from DbObjectDict. It is a dictionary that represents the collection of operator classes in a database.

class pyrseas.dbobject.operclass.OperatorClassDict(dbconn=None)¶: The collection of operator classes in a database

OperatorClassDict.from_map(schema, inopcls)¶

Initialize the dictionary of operator classes from the input map

Parameters:	schema – schema owning the operator classes inopcls – YAML map defining the operator classes
