Types ¶
type IJoinPolicy ¶
type IJoinPolicy interface {
Join(left, right field.IFilterField) bson.D
// contains filtered or unexported methods
}
IJoinPolicy is used to build bson filter which joins two fields (IFilterField) from different collections. It is moved to a separate interface to ensure that the IFilterField interface is not polluted with the logic related to joining fields, since there are different types of joins (left, right, inner, etc.) and each of them has its own logic. It is injected into the IFilterField as a dependency to perform the join.
func NewLeftOuterJoinPolicy ¶
func NewLeftOuterJoinPolicy() IJoinPolicy
type IMergePolicy ¶
type IMergePolicy interface {
Merge(left, right field.IFilterField) bson.D
}
IMergePolicy is used to define the way of merging two fields (IFilterField). It is moved to a separate interface to ensure that the IFilterField interface is not polluted with the logic related to merging fields, since there are different types of merging (override, and, or, etc.) and each of them has its own logic. It is injected into the IFilterField as a dependency to perform different merge operations.
