ucar.ma2.ArraySequenceNested

public class ArraySequenceNested
extends ArrayStructure

Handles nested sequences: a 1D array of variable length 1D arrays of StructureData. Uses same technique as ArrayStructureMA for the inner fields; data storage is in member arrays. Used only by opendap internals. Example use:

    ArraySequence aseq = new ArraySequence( members, outerLength);
    for (int seq=0; seq < outerLength; seq++) {
      aseq.setSequenceLength(seq, seqLength);
    }
    aseq.finish();
