Examples of org.pdf4j.saxon.value.SequenceExtent

org.pdf4j.saxon.value.SequenceExtent
A sequence value implemented extensionally. That is, this class represents a sequence by allocating memory to each item in the sequence.

                AtomicValue[] values = new AtomicValue[children.length];
                for (int c=0; c<children.length; c++) {
