  • Method Summary

    Modifier and Type
    Method
    Description
    AuthenticationInformation
    getAuthenticationInformation()
    Returns the authentication information of this federation member or null if there is no authentication information for this federation member (in which case it can be assumed that this federation member can be accessed without authentication).
    int
    getID()
    Returns an identifier of this federation member, which should be unique (independent of the type of federation member).
    String
    getServiceURI()
    Returns the (unique) service URI of this federation member.
    boolean
    isSupportedPattern(SPARQLGraphPattern p)
    Returns true if this federation member supports answering the given graph patterns in a single request.
    boolean
    supportsMoreThanTriplePatterns()
    Returns false if the only types of graph patterns that can be answered by a single request to this federation member are triple patterns.

  • Method Details

    • getID

      int getID()
      Returns an identifier of this federation member, which should be unique (independent of the type of federation member).

    • getServiceURI

      String getServiceURI()
      Returns the (unique) service URI of this federation member. The service URI is the URI via which the federation member is referred to in the SERVICE clauses.

    • getAuthenticationInformation

      AuthenticationInformation getAuthenticationInformation()
      Returns the authentication information of this federation member or null if there is no authentication information for this federation member (in which case it can be assumed that this federation member can be accessed without authentication).

    • supportsMoreThanTriplePatterns

      boolean supportsMoreThanTriplePatterns()
      Returns false if the only types of graph patterns that can be answered by a single request to this federation member are triple patterns.

      Notice that a return value of true does not mean that the federation member supports arbitrary graph patterns, but only that it supports more than only triple patterns. For a more specific way of checking, use isSupportedPattern(SPARQLGraphPattern).

    • isSupportedPattern

      boolean isSupportedPattern(SPARQLGraphPattern p)
      Returns true if this federation member supports answering the given graph patterns in a single request.
