      Adds a collections of triple paths to the where clause.
      Parameters:
      collection - The collection of triple paths to add
      Returns:
      This Builder for chaining.

    • addWhere

      T addWhere(FrontsTriple t)
      Adds a triple to the where clause.
      Parameters:
      t - The triple to add
      Returns:
      This Builder for chaining.

    • addWhere

      T addWhere(Object s, Object p, Object o)
      Adds a triple or triple path to the where clause. See AbstractQueryBuilder.makeTriplePath(java.lang.Object, java.lang.Object, java.lang.Object) for conversion of the param values.
      Parameters:
      s - The subject.
      p - The predicate.
      o - The object.
      Returns:
      This Builder for chaining.

    • addWhere

      T addWhere(AbstractQueryBuilder<?> whereClause)
      Adds the elements from the whereClause to this where Clause.
      Parameters:
      whereClause - The whereClause to add to this statement.
      Returns:
      This Builder for chaining.

    • addWhereValueVar

      T addWhereValueVar(Object var)
      Add a variable or variable and values to the value statement. The first var (or first item in a collection) is converted to a variable using the makeVar strategy. A variable may be added multiple times, doing so will append values to the list of variable values. The order in which variables are added to the values table is preserved. Adding a collection as the var will use the first object in the collection as the var and the remaining objects as values. Values are created using makeNode() strategy except that null values are converted to UNDEF.
      Parameters:
      var - The variable or collection to add.
      Returns:
      The builder for chaining.
      See Also:

    • addWhereValueVar

      T addWhereValueVar(Object var, Object... values)
      Add a variable and values to the value statement. The var is converted to a variable using the makeVar strategy. A variable may be added multiple times, doing so will append values to the list of variable values. The order in which variables are added to the values table is preserved. Values are created using makeNode() strategy except that null values are converted to UNDEF.
      Parameters:
      var - The variable to add.
      values - The values for the variable
      Returns:
      The builder for chaining.
      See Also:

    • addWhereValueVars

      <K extends Collection<?>> T addWhereValueVars(Map<?,K> dataTable)
      Add a data table to the value statement. Each key in the map is used converted into a variable using the makeVar strategy. The order in which variables are added to the values table is preserved. Variables are added in the iteration order for the map. It may be advisable to use a LinkedHashMap to preserver the insert order.
      Parameters:
      dataTable - The data table to add.
      Returns:
      The builder for chaining.
      See Also:

Variables will always be in the order added to the values table.
      Parameters:
      values - the collection of values to add.
      Returns:
      The builder for chaining.
      See Also:

There must be sufficient entries in the list to provide data for each variable in the table. Values objects are converted to nodes using the makeNode strategy. Variables will always be in the order added to the values table.
      Parameters:
