Method Detail

hasNext

boolean hasNext()
                throws IOException

See if theres more StructureData in the iteration

Returns:

true if more records are available

Throws:

IOException - on read error

next

StructureData next()
                   throws IOException

Get the next StructureData in the iteration.

Returns:

next StructureData record.

Throws:

IOException - on read error

setBufferSize

void setBufferSize(int bytes)

Hint to use this much memory in buffering the iteration. No guarentee that it will be used by the implementation.

Parameters:

bytes - amount of memory in bytes

reset

StructureDataIterator reset()

Start the iteration over again.

Returns:

a new or reset iterator.

getCurrentRecno

int getCurrentRecno()
