Example 1 with GraphWithPerform

use of org.apache.jena.graph.impl.GraphWithPerform in project jena by apache.

the class GraphUtil method deleteIteratorWorkerDirect.

/**
     * Delete the triples supplied by an iterator. This function is not "concurrent
     * modification" safe; it assumes it can use the iterator while deleting from the
     * graph.
