Example 11 with WonMessageType

use of won.protocol.message.WonMessageType in project webofneeds by researchstudio-sat.

the class LinkedDataWebController method readConnectionsOfAtom.

/**
 * Get the RDF for the connections of the specified atom.
 *
 * @param request
 * @param identifier
 * @param deep If true, connection data is added to the model (not only
 * connection URIs). Default: false.
 * @param page taken into account only if client supports paging; in that case
 * the specified page is returned
 * @param resumeBefore taken into account only if client supports paging; in
 * that case the page with connections URIs that precede the connection having
 * resumeBefore is returned
 * @param resumeAfter taken into account only if client supports paging; in that
 * case the page with connections URIs that follow the connection having
 * resumeAfter are returned
 * @param type only connection events of the given type are considered when
 * ordering returned connections. Default: all event types.
 * @param timestamp only connection events that where created before the given
 * time are considered when ordering returned connections. Default: current
 * time.
 * @return
