Constructor Detail

ArrayStructureBBpos

public ArrayStructureBBpos(StructureMembers members,
                           int[] shape,
                           ByteBuffer bbuffer,
                           int[] positions)

Construct an ArrayStructureBB with the given ByteBuffer.

Parameters:

members - the list of structure members.

shape - the shape of the structure array

bbuffer - the data is stored in this ByteBuffer. bbuffer.order must already be set.

positions - offset from the start of the ByteBufffer to each record. must have length = with shape.getSize()
