Detailed Description

Global variable that states whether the type and operator Oid caches have been initialized.

• Global array that enables the mapping MeosType -> Oid
• Global hash table that enables the mapping Oid -> MeosType
• Global hash table that enables the mapping meosOper -> Oid
• Global 3-dimensional array that enables the mapping meosOper -> Oid in MobilityDB. The first dimension corresponds to the operator class (e.g., <=), the second and third dimensions correspond, respectively, to the left and right arguments of the operator. A value 0 is stored in the cell of the array if the operator class is not defined for the left and right types.
