- Enclosing class:
public static interface BigSegmentStoreTypes.MembershipA query interface returned by
It is associated with a single user, and provides the ability to check whether that user is included in or excluded from any number of Big Segments.
This is an immutable snapshot of the state for this user at the time
BigSegmentStore.getMembership(String)was called. Calling
checkMembership(String)should not cause the state to be queried again. Implementations should be safe for concurrent access by multiple threads.
All Methods Instance Methods Abstract Methods Modifier and Type Method Description
checkMembership(java.lang.String segmentRef)Tests whether the user is explicitly included or explicitly excluded in the specified segment, or neither.
java.lang.Boolean checkMembership(java.lang.String segmentRef)Tests whether the user is explicitly included or explicitly excluded in the specified segment, or neither.
The segment is identified by a
segmentRefwhich is not the same as the segment key: it includes the key but also versioning information that the SDK will provide. The store implementation should not be concerned with the format of this.
If the user is explicitly included (regardless of whether the user is also explicitly excluded or not-- that is, inclusion takes priority over exclusion), the method returns a
If the user is explicitly excluded, and is not explicitly included, the method returns a
If the user's status in the segment is undefined, the method returns
segmentRef- a string representing the segment query
- boolean for explicit inclusion/exclusion, null for unspecified
