Example 17 with BindingBuilder

use of org.apache.jena.sparql.engine.binding.BindingBuilder in project jena by apache.

the class TransformFilterInequality method buildTable.

    Table table = TableFactory.create();
    // Although each filter condition must apply for a row to be accepted
    // they are actually independent since only one condition needs to fail
    // for the filter to reject the row. Thus for each unique variable/value
    // combination a single row must be produced
    BindingBuilder builder = Binding.builder();
