    Modifier and Type
    Method
    Description
    TriplePattern
    applySolMapToGraphPattern(SolutionMapping sm)
    Applies the given solution mapping to this graph pattern and returns the resulting graph pattern in which all occurrences of the variables bound by the given solution mapping are replaced by the RDF terms that the solution mappings assigns to these variables.
    org.apache.jena.graph.Triple
    asJenaTriple()
    Returns a representation of this triple pattern as an object of the class Triple of the Jena API.
    boolean
    equals(Object o)
     
    Set<TriplePattern>
    getAllMentionedTPs()
    Returns a set of all triple patterns that are contained within this graph pattern.
    Set<org.apache.jena.sparql.core.Var>
    getAllMentionedVariables()
    Returns the set of all variables mentioned in this graph pattern, except for the variables that occur only in expressions (in FILTER or in BIND).
    Set<org.apache.jena.sparql.core.Var>
    getCertainVariables()
    Returns the variables that are guaranteed to be bound in every solution mapping produced for this graph pattern.
    int
    getNumberOfTermMentions()
    Returns the number of times any RDF term is mentioned in this graph pattern (if the same term is mentioned multiple times, then each of these mentions is counted), but ignores terms mentions in expressions (in FILTER or in BIND).
    int
    getNumberOfVarMentions()
    Returns the number of times any variable is mentioned in this graph pattern (if the same variable is mentioned multiple times, then each of these mentions is counted), but ignores variable mentions in expressions (in FILTER or in BIND).
    Set<org.apache.jena.sparql.core.Var>
    getPossibleVariables()
    Returns the variables that may be bound in solution mappings produced for this graph pattern, but that are not guaranteed to be bound in every such solution mapping.
    int
    hashCode()
     
    static SPARQLGraphPattern
    merge(TriplePattern tp, org.apache.jena.sparql.syntax.Element elmt)
    Merges the given triple pattern into the given graph pattern.
    BGP
    mergeWith(BGP bgp)
    Return a BGP that contains this triple pattern plus all triple patterns of the given BGP.
    SPARQLGraphPattern
    mergeWith(SPARQLGraphPattern other)
    Merges this graph pattern with the given graph pattern, using join semantics, and returns the resulting, merged pattern.
    BGP
    mergeWith(TriplePattern other)
    Returns a BGP that contains this triple pattern plus all triple patterns of the given BGP.
    int
    numberOfVars()
    Returns the number of distinct variables in this triple pattern.
    String
    toString()
    Returns a string representation of the triple
