Class DefaultMembershipCache

java.lang.Object

com.atlassian.confluence.user.crowd.DefaultMembershipCache

All Implemented Interfaces:

MembershipCache

public final class DefaultMembershipCache
extends Object
implements MembershipCache

The cache maps a CachedCrowdMembershipCacheKey representing a user (or group) in a particular directory to a Map<String, String> where each entry in the map represents a group that the user (or group) is a member of. The key of each Map entry is the lowercase name of the user or child group. The value is the case-preserved actual name of the entity.
